We solve the problem with blocking pages by Avast antivirus. What to do if the antivirus blocks the Internet Antivirus blocked the program how to unblock

It often happens that the antivirus blocks sites that are quite reliable, for example, in contact or classmates. Everyone can do this: Kaspersky, Nod (eset), Avast (avast), Avira, Avg and others. Why is this happening and how to fix it.

If the antivirus mistakenly blocks sites, then you may not be mistaken. The fact is that in contact or classmates, where you want to enter, in fact, they may turn out to be dummy.

Almost the same address (one letter changed) and the same content, but they were created by scammers to steal passwords.

These sites in contact and classmates (not only) are almost indistinguishable from real ones. , nodes, avast, avg know about them - so they block them to protect you from stealing passwords or viruses.

If you are completely confident in the reliability of blocked sites, then this can be fixed without disabling antiviruses. Everyone has such opportunities. Since I now have a node installed, I will show how this is done using its example.

In order for the antivirus to erroneously no longer block sites that you think are reliable, you need to manually add them to its database. To do this, by clicking on it at the bottom of the tray, launch it and click settings. See picture:

Now look at the picture and add sites (in contact, classmates) to the database that the antivirus should not block.

You can add as many as you want, the main thing is not to be mistaken in their reliability.

You can do the same with other antiviruses that, in your opinion, mistakenly block sites. Everyone has these mechanisms. I showed Eset as an example, since I currently have it installed. In this way, you simply add the site to the exceptions.

You can also add files (programs) to exclusions in the same way so that the antivirus does not block them, only the settings are slightly different (you need to select other options). Of course antivirus, but it’s better not to do that and never send SMS.

You can drive a phone number, and sometimes you need to, but you can’t send SMS in any case. The phone number is entered so that you can later recover the password. Such functions have classmates, vkontakte, emails, skype, banking sites and the like.

There is nothing wrong with this, but on the contrary, it is even better, because then no one can change your password without your knowledge. Sorry, I digressed a little from the main topic of why the antivirus blocks trusted sites.

However, there is nothing more to write about. Antivirus programs block what, in their opinion, is very dangerous for you, if they are in doubt, they simply warn you, although it often happens that developers quite consciously make sure that their antiviruses block reliable sites and programs.

They have their own reasons (they protect their interests), then manually add sites and files to exceptions, using the method described above, or simply disable them for a while, although disabling does not always help. Good luck!

If your Avast, Nod, Avira, Kaspersky, Doctor Web or any other antivirus has begun to block your browser, showing a message that it is trying to open a malicious site, then your computer is infected with adware or an adware virus. At the same time, Chrome, Firefox, Yandex, Opera, Internet Explorer, Edge or another browser you use will show a message that the page you are trying to open is not available. If you try to uninstall the browser and install it again, then you will not solve the blocking problem, since most often the ad virus is written deep into the system and it cannot be removed by simply reinstalling the browser.

Adware is a piece of software that is used as a tool for distributing online advertisements. Adware is designed to flood the browser with a constant stream of ads. In addition, such malware can forcibly redirect the user instead of the site he needs to another - an advertising or malicious site. Most often, this redirect detects the antivirus installed on the computer and blocks it. Such blocking leads to the fact that it becomes almost impossible to use the web browser for its intended purpose.

Adware usually infects only Chrome, Firefox, Yandex, Opera, Internet Explorer and Edge by changing their settings or installing various adware and malicious extensions. But there are cases when malicious programs infect all browsers installed on the computer or even other programs, changing the object property of their shortcuts located on the Desktop. This leads to the fact that every time you start a program or browser, through an infected shortcut, instead of it, a browser will open in which a malicious site will start loading. This detects the antivirus and blocks the browser from launching, displaying the standard blocking message.

Therefore, it is very important to follow the instructions below. It will help you remove adware, remove browser blocking and clean your computer of all intrusive ads. Moreover, this step-by-step instruction will help you restore browser settings and get rid of other malware that may have entered your computer along with adware.

After much trial and error, I noticed the "Check for viruses" function, indicated on the installation Windows disks. If the antivirus can be overcome even before the operating system has loaded, it will not have to be installed from scratch along with the loss of content hard drives and lots of time. On the site of the beloved Doctor Web, I downloaded the disk image, then used Nero and burned the CD. When the image was deployed to disk, it was possible to start working with the antivirus itself. After that, I set the BIOS to boot from the drive and clicked Start to start the scanner. When the scan was over, I selected everything that DrWeb found and removed the "enemies" from hard drive. After returning the BIOS settings and rebooting the system, I realized that the goal was achieved and it was possible to remove malicious files from startup via Start-Run-msconfig.
Alas, it is very often impossible to root out cunning viruses from a running OS, but the proposed method will certainly work with any virus threats to the Windows family.

In general, DrWeb is a completely universal product. In combination with “straight hands”, he is able to treat OSes hopelessly eaten away by viruses. There is another convenient way to remove malicious viruses without fiddling with the BIOS and burning blanks. The program Dr. Web Cure It, which does not need to be installed - just run the *.exe file. The program can be taken on the official website of the product.

Solving the problem of a virus that does not allow you to install an antivirus

So, to start fighting the virus, you need to start the OS in safe mode by holding F8 while turning it on. After Windows boot you need to run the DrWebCureIt.exe executable file and wait until the application finds malicious files. You will have to stock up on many hours of patience, but it will pay off. It is advisable to follow the progress of the search: Doctor Web will show different files and offer options for dealing with them. You need to delete the found files with caution, non-specialists should consult with experienced people so as not to demolish part operating system. If the OS does not allow you to delete files through the antivirus, you can try sending them to the Recycle Bin manually. If, when trying to get rid of the file, a window pops up saying “the file is currently in use and cannot be deleted!”, you need to reboot into safe mode again and repeat the procedure.

Having returned Windows to its native full mode, you need to go to the Task Manager (Ctrl-Alt-Delete) and turn off non-system processes one by one. But even here you don’t need to get inflamed and delete everything in a row, otherwise Windows may simply refuse. When the extra processes and services are cleaned out, you need to try again to delete the harmful file.
Slightly more advanced users, who tend to create checkpoints before OS problems occur, can try to restore the system to its clean state before the appearance of viruses.

The most enlightened computer owners meticulously install Windows and all their favorite applications on a clean and pre-partitioned HDD, remember the image of the system disk (using the Acronis software) and, if necessary, replace the virus-infected system disk its original way.
