Hello, friends!
Today we are analyzing a very hot topic, which is dedicated to online fraud.

In this article I will try to answer such popular questions: “Why can't I go to the social networks“ Odnoklassniki ”and“ VKontakte ”, to the mail and other sites?”.

Such troubles, when a user loses access or cannot enter his page on social networks, as a rule, arise as a result of changing the hosts file. What is this file, where is it located and how to edit it, we have analyzed. I recommend that you read this article.

File hosts can be changed deliberately, for example, by the system administrator of your company (office) or as a result of a virus attack on the computer. Today we will analyze exactly the last case.

I suppose most of you know, or at least have heard of, terms such as phishing or farming. What is the difference between them and how do you know if you have become a victim of a virus attack? Today I will tell you how the infection most often occurs, as a result of which you cannot access social networks, and I will give an example of a simple farming attack.

Let's start with a simpler type of virus attack - phishing (from English fishing - fishing). The purpose of this fraud is to gain access (login and password) to user data. With the help of an e-mail that came to your mail, disguised as a message from various services, for example, from social networks, the user follows the link and gets to a fake site that looks like an official one. Further, on this fake page, he enters his username and password and allows the fraudster to gain access to his account, and sometimes to bank accounts.

Farming - this is disguised phishing or "fishing" according to the new rules. This is a more dangerous and advanced type of fraud, the purpose of which is to automatically redirect to a fake resource. Your vigilance is lulled by a completely "correct" link, and only you click on it - the malicious code does its job and redirects you to a previously prepared copy of the site. While a phishing email can still be ignored, a pharming attack is much more difficult to detect.

To implement pharming attacks, as a rule, two main methods are used - manipulating the hosts file or changing dns information.

How does the virus get infected?

The malicious code is disguised and distributed, for example, in the form of a social media application. These can be applications for opening access to a closed page or for likes, etc. Perhaps you just followed the link and ended up on a suspicious site where a window popped up prompting you to install an update. You download this fake (dummy) application and install it. After installation, the system (and in particular the hosts file itself) undergoes certain changes.

After the virus has changed the hosts file, access to popular websites and resources with antivirus software is blocked, or the user is redirected to fake pages that look like popular resources (social networks, mail services, etc.), where an inattentive user enters his credentials, and thus they get to the attackers.

Let's say your system has been infected and a virus has changed the hosts file. You, suspecting nothing, open your browser and go to your page on the social network, but you get not to the official page, but to a fake one. Fake, as a rule, is not much different from the official one, and you most likely will not notice it. You enter your data, password and send them to the scammer. Congratulations, you are the victim of a farming attack!

I can't log into classmates or my account is blocked

When you go to your page, as a rule, windows appear that say that you need to enter a mobile phone number.

Messages can be different: “Account has been hacked”, “Spam is being sent from your account” and other messages with similar meaning. But in all cases, you are asked about one thing - to enter a phone number to confirm something.

As you may have guessed, this is a basic scam. Entering the number and the subsequent confirmation code will result in the withdrawal of a certain amount of money plus the loss of the password from social network (in this case, from Odnoklassniki).

This attack can be carried out on any page: on social networks (Odnoklassniki, Vkontakte, Facebook, etc.), mail or Sberbank online.

What to do if your account is hacked?

The first step is to check the hosts file. The hosts file is located in the system partition on the disk C: \\ Windows \\ System32 \\ drivers \\ etc \\ hosts

As you can see in the screenshot above, the hosts file has been changed. In this case, when accessing social networks vk. com and ok.ru are redirected to fake pages.

As a reminder, the default hosts file looks like this:

Select the extra lines and delete. We save the changes. By the way, if you have any problems editing the hosts file, I recommend reading.

If you cannot restore the hosts file on your own, then we will use a solution from Microsoft. Just go to link and follow the official instructions on the company page.

Launch command line (in administrator mode), where we enter the following command: and press Enter. Reboot your computer.

These manipulations should help solve your problem with logging into social networks or with the loss of access to social networks, mail and other services. I recommend reading another useful article: “

I can't go to the site classmates. Solution.

Many of our readers write: “I can't go to my classmates. What to do?". Typically, such troubles occur as a result of viruses that modify the contents of the hosts file. The fact is that this file allows you to create a so-called "black list" of sites. For example, if you are an employer and you know that your employees communicate on Odnoklassniki or Vkontakte during the working day instead of working hard for the good of the company, then you can block the ability to visit these sites.

Please note that if you register the Odnoklassniki and Vkontakte sites in the hosts file in a certain way, you will not be able to access them even if you use different browsers (Opera, Google Chrom, Firefox, etc.).

In order to unblock the ability to enter the Odnoklassniki website, do the following:

1. Go to the C: \\ Windows \\ system32 \\ drivers \\ etc \\ folder.
2. Open the hosts file located there with notepad.
3. Bring the hosts file to its original (working) state, depending on the installed operating system:
   • If your computer is running windows management XP, then the hosts file after the comments should contain only one line - 127.0.0.1 localhost... Everything else needs to be removed.
   • If the computer is running Vista - 27.0.0.1 localhost :: 1 localhost.
   • If the computer is running Windows 7 - # 127.0.0.1 localhost # :: 1 localhost.

As the saying goes, everything seems clear, but there may be two or even three files with similar names, as in the case below.

When you look at the etc folder, you can see that there is a hosts file without an extension, as well as the hosts.ics and hosts.txt files. Which file to edit? If you are using a browser Internet Explorer or Mozilla Firefox, then you need to edit the hosts file without the extension. If google browser Chrom, then with the txt extension. In short, it's better to edit both at once.

It may happen that after you open the hosts file (without an extension) using notepad, it looks like everything will be in order, but this is only at first glance. For example, when I opened the hosts file, at the top of the document there was no list of any prohibited site addresses, but scrolling down the document a couple of screens, I saw a "black list", it looked like this:

The red frame marks the addresses related to the Odnoklassniki site, and above, the green frame marks the Vkontakte addresses.

Let me remind you that each site has its own IP address, i.e. perfectly you can go to Yandex by typing in the address line not www.yandex.ru, but its IP address 93.158.134.3. In the same file, the name of the same Yandex is associated with a completely different IP and instead of typing www.yandex.ru in the address bar, you will be taken to a completely different site. If this site does not work (a site with such an IP does not exist), then the browser will give an error when loading the page.

Please note that in the list, besides "in contact", "classmates", there are all the main search engines, and as for "in contact", the addresses are typed with different variations. So everything, as they say, is thoughtful, everything is done so that you cannot get to the most popular sites.

So, see what the contents of the file looks like hosts(Windows XP) if no one tried to make changes to it.

In the first lines you see the # sign - the comment line begins with this sign and everything written in it by the computer is not perceived. In short, in the comments it is written what information and how should be located in the hosts file.

So, what needs to be done to remove the bans from visiting your favorite sites? You must convert the contents of the hosts file to the example shown. Comments can be removed or left - there is no difference.

Everything seems to be clear, but after changing the file it cannot be saved, the following message appears:

If you are working in Total Commander under an administrator account, you can simply select the hosts file and press the F4 (edit) key on your keyboard. Then you can modify the file and save it.

When opening a file with the txt extension, you can launch Notepad with administrator rights (right-click on the icon and select the "Run as administrator" command.

If for some reason you cannot save the file in this way after changing, in extreme cases, you can load a second operating system (if it is on the computer) and make the necessary changes from under it. If the second operating system is not installed, then it can be started from a bootable disk type.

If you have changed the contents of the specified files (hosts and hosts.txt), but still cannot contact other popular sites, then just close your browser and start it again.

Additionally, for site users, the site has a video “I can't go to classmates. Solution"

Attention!Remember to check your computer for viruses. I recommend using the "CureIt" curing utility from the Doctor Web site. Read about how to use the utility.

If you have problems logging into classmates, this article will help you solve the most common problems. Step-by-step instructions with illustrations are designed specifically for self-help troubleshooting when people are looking for an answer " I can not go to classmates on my page».

You can not go to Odnoklassniki for the reason:

Forgot your page address in classmates.

One of the most common cases when people are just starting to learn how to use the Internet and if the browser settings fail, they do not know and, accordingly, cannot enter. Launch the browser: Opera, Mozilla firefox, Chrome.

As a rule, the program shortcut is located on the desktop or taskbar, we double-click on it with the mouse.

In the address bar, enter the address: odnoklassniki.ru or ok.ru

In the window that opens, enter your username and password. If the data was previously saved, then there will be an automatic login to Odnoklassniki without a password.

Forgot your username or password from Odnoklassniki ..

Go to the page of the social network site and click "Forgot your password".

You will be prompted to enter your login, email address or phone number. After entering the data, a message will be sent to your e-mail or phone, which contains the access code for the page. After that, you will need to re-invent the password combination for entering Odnoklassniki.

Access to classmates is closed.

Very often, in offices or companies, social networks are specifically blocked so that employees do not waste their work time. But there are times when you really need to read or send a message, congratulate someone, or just take the necessary information from your page. What to do in this case?

One of the options is to go to the site from the phone or use the special Anonymizer service.

The anonymizer allows you to bypass in most cases the prohibitions of system administrators and installed network filters.
Several services that provide an entrance to Odnoklassniki:
- http://biglu.ru
- kalarupa.com

They ask you to enter a phone number or send an SMS.

You will be asked to enter the phone number if you entered the page from different Ip addresses, and they are very different geographically. This may occur while traveling, using an anonymizer, or your page has been hacked (the attacker lives in another city), sent SPAM. In the first two cases, there is nothing wrong, you need to confirm the phone number and enter the code in the received SMS message.

If you have not traveled and do not use the anonymizer for Odnoklassniki, there is a high probability that your page has been hacked. We strongly recommend that you provide your phone or email number and restore access.

Go to the page settings and check your data (phone number, mail), and then change your password.
If you are asked to enter a phone number, and then send an SMS message to confirm, these are scammers. To restore access, the official website of the social network never requires you to send SMS to any number. It is difficult for a visually unprepared person to distinguish a real page from a fake one, so one of the recommendations is to try to access your wanderer from another computer or via a smartphone (). If the login occurs without problems, it means that there is a virus on your computer or the Host file has been specially modified.
How to deal with the virus in Odnoklassniki, read on.

The virus blocks the Odnoklassniki website.

If a virus blocks a site from your computer or go to the site and you are asked to send an SMS message, and from another you can freely go to your page, then you need to take appropriate measures.

First step. Check Host file.

It is located at C: \\ Windows \\ System32 \\ drivers \\ etc \\ hosts.

We click on it, open it with notepad. The last line should contain:
127.0.0.1 localhost,
After this line there should be no other records, all unnecessary should be deleted. Look carefully to see if there is any scrolling in the notebook, because sometimes the entries are hidden at the very end of the page, with many blank lines added before that. If the hosts file is in order, the next step is to check your computer for viruses.

From the official website, we download a choice of one utility for searching and removing viruses:
- Kaspersky Virus Removal Tool http://www.kaspersky.ua/antivirus-removal-tool
- Dr.Web CureIt! https://free.drweb.ru/cureit/
- Malwarebytes Anti-Malware https://ru.malwarebytes.org/antimalware/

For example, Dr.Web CureIt!

Download the utility and run it.

In the window that appears, click "Start check"

At the end of the scan, the program will display a list of found viruses that have been detected and neutralized (quarantined). After restarting your computer, you can try to go to the Odnoklassniki website.

Remember! In order not to catch the virus again, follow simple rules.

• no need to open suspicious emails from strangers that come by mail;
• enter the username and password from classmates on other sites, except the official one;
• click on suspicious pop-up windows that ask you to perform this or that action;
• be sure to install an antivirus on your computer.

It is interesting:
Grandma prepares croutons for her grandson for dinner. She uses a small skillet to prepare them, which can only hold two slices of bread. It takes one minute to fry each side of a slice of bread. To cook three croutons, grandmother needs only three minutes instead of the obvious four. How does she manage to do this?

Social networks, like the Internet in principle, are a huge mystery to users. Here very often there are various failures and malfunctions that interfere with the comfortable work on a particular service. Recently, users have been complaining and learning from other people the answer to this question: “I can’t go to Odnoklassniki. What should I do?”. There can be a huge number of reasons for this. Some you can fix, but with something you just have to come to terms. In practice, it turns out that the user himself is usually to blame for what is happening. And it is in his power to fix everything. Can't go to Odnoklassniki? Then it is worth finding out the cause of this phenomenon and eliminating it, if this is possible. What options can be at what is happening?

the Internet

The first thing that can be assumed is that your Odnoklassniki malfunctioning is a common complaint. But sometimes a similar phenomenon is observed due to the carelessness of users. Internet failures, as well as various accidents at the station with your provider - this is what can lead to the described situation.

To know for sure that the Internet connection is not the fault here, pay attention to the operation of the browser and applications that need the network to function. Does everything work except the social network? Then the reason is clearly not on the Internet. Can't work with the Internet at all? Quite a different matter - you will need to find the cause of the network failure, fix it and resume connection attempts.

Browser

You are faced with a problem called "I can not go to Odnoklassniki". Writes that the page is unavailable? If the option with a failure of the Internet connection did not work, you can try to change your browser. Sometimes these applications also have various failures and problems, which are simply they block access to websites in an incomprehensible way.The emphasis, as practice shows, is on social networks and blogs.

You can either completely uninstall and reinstall the current browser, or install another application on your computer. Sometimes this technique helps. And a question like: "Why can't I go to the Odnoklassniki page?" disappears by itself. In reality, this happens very rarely. After all, social networks refuse to work for a reason. Most often, the reasons lie either in the operation of the master server, or in your operating system. Pay close attention to these two areas.

Phone

But what if you are faced with a situation called "I can not enter Odnoklassniki from my phone"? This phenomenon can usually be fixed easily and simply - try again to authorize the essence later. In addition, it is advisable to reboot the system. mobile device... Maybe there was some minor glitch that is now interfering with the mobile browser.

Alternatively, try to log in to the social network using another mobile phone. If this succeeds, the problem is with your device. No? Then you do not need to slander on your mobile. Look for the cause of the problem elsewhere. Most likely, you will not be able to fix the situation on your own. Why? Let's try to figure it out.

Server crash

Someone complains "I can not enter Odnoklassniki (from a computer, tablet or phone - it doesn't matter)". How to deal with such a phenomenon? Often, social networks are attacked by various competitors and hackers. This causes the main server to malfunction. This phenomenon, in turn, becomes the main reason for the refusal of a social network (or other site) from work.

With all this, pay attention - the problem will begin to be observed not only on your account, but also on other users. Contact your friends and find out if they can go to Odnoklassniki. No? Please wait a while. And read the news. Usually, hacker attacks and server failures of well-known sites are written in news feeds.

Of course, nothing depends on users in such cases. All that remains is to be patient and wait for the site administrators to set up the main server. After that you will be able to log in. With rare exceptions - when the cause of the problem called "I can't log into Odnoklassniki" appeared through no fault of a system failure of the main hosting server.

Prevention

Another point worthy of attention is nothing more than technical and preventive maintenance on the site. No hosting is safe from them. And similar "events" are held on a regular basis from time to time. Do not be surprised if suddenly you are faced with a problem that sounds like "I can not go to Odnoklassniki. The page is unavailable." It is better to ask if any work was planned by the administration of the social network.

By the way, surprises can be avoided. It is enough to carefully read the news and messages of the hosting administrators and moderators. Users try to warn in advance about preventive maintenance. At the same time, keep in mind - you may not be authorized, but from friends - quite. It all depends on personal luck. It is desirable to repeat attempts to work with Odnoklassniki after a certain period of time. If you find news, where the exact time frame for preventive maintenance or technical work is written, approximately 10-15 minutes after the end of these, everything should work.

Programs

Occasionally, problems with logging into social networks are provoked by content installed on your computer. Especially if it can contain malicious files and even viruses. If you are faced with a problem called “I can’t go to Odnoklassniki,” just see how many are running on your computer. Pay attention only to software that requires an Internet connection.

Alternatively, close this kind of application and resume trying to work with the social network. If the actions have brought a result, henceforth simply do not run so many programs at the same time that require an Internet connection. No result?

Remember which apps you installed before the problem occurred and get rid of them. This technique also helps very often. Pay special attention to software downloaded from unreliable and unreliable sources. These are the main threats to your computer. Nothing helped anyway? Maybe the reason is different?

operating system

The operating system is another reason why your social media authorization may become impossible. And not only in Odnoklassniki. Some system crashes can disrupt the browser and the Internet in general. Hence, it becomes impossible to log in to social networks and go to various sites that work normally on other computers.

Thinking about the topic "I can't go to Odnoklassniki. What to do?" Try to roll back the system to a time when authorization was still available to you. Just to get started, check the options with technical work and hacker attacks. In addition, do not rush to agree to a rollback of the operating system if problems are observed only in Odnoklassniki. And with all other sites and social networks, everything is in order.

This is not true? Feel free to roll back the system and see the result. It is advisable to reinstall the browsers after the implementation of the idea. Rollbacks often require this operation. Is there no use anyway? There is no need to despair. There are several alternative solutions to this problem.

Breaking

Or maybe your account was just hacked? Remember if you have recently used any suspicious content for the Odnoklassniki social network. If such was the case, there is a huge chance of hacking. Your task is to get your account back. In practice, it is difficult to do this if you have not entered and confirmed your real data. The Odnoklassniki administration will have to somehow prove that you are the true owner of the profile. This is only relevant when home page site, you can still go.

If you have the opportunity, try to log in from someone else's account. Or even register another page for yourself. And forget the old one. Suspicious content, if any, must be removed from the system immediately. Usually, applications for cheating friends, as well as software that offer an extension of the standard capabilities of a social network, fall under suspicion.

Registry

In case of regular problems, you can try to resort to one trick. If you cannot access Odnoklassniki or any other social network, your music and videos do not load, it's time for a computer. It is advisable to use CCLeaner for this. Maybe your computer just doesn't have enough resources to connect to a specific page. Cleaning the registry will fix this problem.

There is no need to hope for success. But if it helped you, rejoice. And do not forget to continue to carry out regular on the computer. It is advisable to refer to this procedure at least once a month. It helps to get the operating system working.

Viruses

We are almost at the end of our topic today. As practice shows, most often it is impossible to visit Odnoklassniki and social pages is generally caused by viruses on the computer. The problem is easily solved - it is enough to get rid of malicious files in the system (in other words, to cure it). And then the performance of the social network will return.

In some cases, it is more advisable to simply reinstall the operating system. The method is relevant for situations where viruses have already seriously damaged the computer. Do not rush to look at Odnoklassniki immediately after reinstallation. First, install the drivers for the network and sound cards.

Host

The last trick is working with the so-called on a computer. Certain viruses are capable of blocking visits to certain sites without the user's knowledge. This does not mean that all social networks will become inaccessible to you. Only selectively.

To be able to go to Odnoklassniki, just find hosts on your computer (it is stored in the etc folder on your hard disk, the section with your operating system), open it with notepad, erase all contents and save changes. Or delete it altogether while holding shift. Restart your computer and enjoy the results. So we found out possible reasons problems with authorization in Odnoklassniki. Before starting to deal with the situation, it is advisable to look into the hosts. Most often, the problem lies in this file. Now it's not a problem to answer the question: "Why can't I go to Odnoklassniki?" It is enough to sort out all possible reasons and find the one that suits your case.

Resource Odnoklassniki or OK is one of the most popular sites for social communication in the former CIS.

However, very often there is a problem with the fact that the user cannot go to classmates on his page.

In the same way, you can enter the email address that was specified during registration. Login to the service is free.

What to do if you forgot your OK password

If the user, for some reason, forgot the password for his page on the OK social network, it can be restored using a few simple steps:

• If a letter or SMS with a code does not arrive for more than five minutes, check the spam folder on your phone or account e-mail or contact the site's feedback to get personal help on entering your page.

You also can't log into your account if the page has been attacked, if your account has been hacked, follow these steps:

1. Change the password to access the network as soon as possible;
2. Write to feedback if any data was sent on your behalf;
3. Remove various extensions for classmates from your computer, they may be infected with viruses, with the help of which the account was hacked.

If the resource does not work for a long time

Advice! First of all, try logging into the site from someone else's computer. This will let you know if the resource is working for others or if this problem only occurs on your device. Also check the smartphone version.

Mobile personal page should contain all information as the desktop version.

To enter a blocked (old) or remote page, you should contact the site OS - only they can open access to the previously deleted page.

Go to feedback and in the menu on the left, select "profile blocking".

Then choose the question that best suits your situation - "Why can't I go to the closed page and why is the profile blocked?"

How to enter classmates if the site is added to the list of prohibited

If you are trying to get to the start page in OK, but nothing is visible, most likely, the site was added by the computer administrator to the list of prohibited browser resources.

If you can't go straight to the page,
