Many are interested in the issue of disabling and removing this antivirus. Perhaps someone did not like the product, and someone prefers a free, but no less effective option. Let's take a look at all the methods.

How to disable antivirus

There are several ways to disable the program. On different Windows systems, they are all the same. The most popular is the following:

In this simple way, you can disable almost any antivirus. But this is not reasonable, if you are not going to use it, then you should either re-enable it or remove it.

How to enable Avast antivirus

To enable the protection tool on Windows, double-click the utility icon to open the program window.

Immediately the user will see the message "You are in danger" or "All antivirus screens are disabled." To solve this problem, just click on the button " solve problems».

The second way is that the user right-clicks on the Avast icon on the taskbar. Next, you need to direct the cursor to the item "Manage Avast Screens" and select the option " Enable all screens».

Thus, you can disable and re-enable any antivirus tool. It should be borne in mind that you should not install several antiviruses on the system, as they will conflict and the system may become unstable.

How to uninstall Avast

If the user decides to get rid of the installed program, or replace it with a similar one, it must first be removed. Not recommended use the standard Windows Add/Remove Programs tool, as it does not completely clean up residual files from programs.

If you still decide, proceed as follows:

Using the AvastClear Tool

After downloading and running this application, a message will appear where it is recommended to reboot into safe mode. You can click "YES" or "NO". First, let's try to use the program normally.

Select the version you want to remove. The path is usually set by default, so it remains to click the " Delete».

After that, the program will be deleted. Don't forget to restart your PC.

Avast is deservedly considered one of the best and most stable free antiviruses. However, there are also problems in her work. There are times when the application simply does not start. Let's see how to solve this problem.

One of the most common reasons why Avast antivirus protection does not start is to turn off one or more program screens. The shutdown could have been caused by an accidental press, or a system glitch. There are also cases when the user himself turned off the screens, as sometimes some programs require this during their installation, and then forgot about it.

If the protection screens are disabled, a white cross appears on the Avast tray icon on a red background.

To fix the problem, right-click on the Avast tray icon. In the menu that appears, select the "Manage Avast Screens" item, and then click on the "Enable All Screens" button.

After that, the protection should turn on, as evidenced by the disappearance of the cross from the Avast icon in the tray.

virus attack

One of the signs of a virus attack on a computer may be the inability to enable antiviruses on it, including Avast. This is a defensive reaction of virus applications that seek to protect themselves from being removed by antivirus programs.

In this case, any antivirus installed on the computer becomes useless. To search and remove viruses, you need to use a utility that does not require installation, for example.

Better yet, scan your computer's hard drive from another uninfected device. After detecting and removing the virus, Avast antivirus should start.

Critical crash in Avast

Of course, Avast antivirus problems are rare, but, nevertheless, due to a virus attack, power failure, or other significant reason, the utility can be seriously damaged. Therefore, if the first two ways we described to fix the problem did not help, or the Avast icon does not appear even in the tray, then the most correct solution would be to reinstall the antivirus program.

To do this, you first need to perform a full, followed by cleaning the registry.

Then, on the computer again. After that, starting problems, in most cases, disappear.

And, of course, do not forget to scan your computer for viruses.

Operating system failure

Another reason why the antivirus may not start is a malfunction of the operating system. This is not the most common, but the most complex and complex problem with the inclusion of Avast, the elimination of which depends on the causes and depth of damage to the OS.

Most often, it can still be fixed by rolling back the system to an earlier restore point, when it was still working fine. But, in especially difficult cases, a complete reinstallation of the OS is required, and even replacement of computer hardware elements.

As you can see, the degree of complexity of solving the problem with the inability to start Avast antivirus, first of all, depends on the causes, which can be very diverse. Some of them are eliminated with just two mouse clicks, while others will have to be thoroughly tinkered with.

The antivirus does not function, at the top of the window there is an inscription “Subscription: Days left: 0”, clicking on the “Remove all” button does not give any result. - This situation happened to many users of the free version of the program after a recent update and its transition to version 8. In this article, I will tell you how to resolve this misunderstanding and remain further protected.

At the same time, the user from time to time sees such threatening messages on the screen:

You are in danger! Renewal required now!

This situation arose due to the maniacal determination of the product developers to earn more money on the one hand and the inattention of users on the other.

The problem arose due to the inattention of the user and the maniacal desire of the manufacturer to get the maximum benefit from their product.

So what's now?

1. Uninstalling Avast Internet Security

Go to "Add or Remove Programs" and remove the antivirus:

At the same time, he will warn of danger several times and offer to change his mind:

Warning 1

Warning 2

Warning 3 (Last Chinese))

We boldly ignore all these "terrible things" and mercilessly delete it. At the end of the uninstallation, the antivirus asks to restart the computer, which we will do. Optional, but you can then clean up the system with their proprietary utility Avast Uninstall Utility. You need to do this in Safe Mode.

2. Install Avast Free Antivirus

Perhaps Google Chrome is not such a bad program, but in this case I don’t need it at all (it can also be Google Drive, Google Toolbar, etc.) - in general, we are closely following these moments

Upon completion of the installation, the product must be registered - in this case, we are given a license for a period of 1 year:

You can fill out the questionnaire with any "abracadabra"

3. Turn off AutoSandbox (Sandbox)

Perhaps there is some benefit in this function (unknown programs run in a special environment - a "sandbox" and cannot harm the computer if they are viruses). But in fact, it turns out that a large number of important and necessary programs fall into the category of these “unknown programs”. As a result, the computer starts to hang, slow down and fail more than it works. In general, the function is raw and unfinished, and we recommend disabling it to avoid such problems. In the new, version 8 of the antivirus, this menu item is hidden quite deeply so that without a bottle you can’t figure it out, you had to look for quite a long time. So, go to the "Security" tab - the "File system screen" menu item - the "Settings" button, and in the next window we look for the "AutoSandbox" item and uncheck "Enable AutoSandbox" in it:

4.Software updater

Avast! Software Updater considers the status of the software update on the computer to be CRITICAL

Software updater is one of the innovations of the 8th version of the antivirus. It monitors the updates of other programs responsible for virus protection, such as Adobe Reader, internet browsers, flash player, java, etc. The function is certainly useful, but when at different, unpredictable moments messages begin to pop up that I have “the Opera browser has not been updated”, the existence of which I forgot and don’t remember when I last used it, and I don’t even know when I will whether to use it at all, it starts to annoy very quickly.

Due to not updated Internet Explorer and Adobe Reader, Avast considers the status as THREATY.

And this feature also turns off very quickly. Whether you turn it off is up to you.

5. Conclusions

Antivirus, in principle, not bad, not a panacea of ​​course (like any other antivirus), it happens and at some points (when updating versions, when re-registering) using it resembles walking through a minefield: with almost every action, they try to transfer us to a paid version . If these points are known and taken into account, then using it is quite comfortable and safe.

Hello dear friends!

Today we’ll talk about free antivirus "Avast", or rather, how to fix the problem of its launch. So!

The other day I received a dozen letters at once asking for help fixing the following problem with this antivirus. Quote: Hello! I have this problem: I have been using the free Avast antivirus for more than a month and everything was fine. But three days ago I ran into a problem that I still do not understand. The problem is this: when the system starts, at the bottom of the monitor (in the tray), the Avasta icon is crossed out with a red cross. Hovered over and saw that the system is not protected. When you try to start the protection, nothing happens! That is, nothing at all! I already rebooted the system ten times, and manually twisted something there - zero! What to do? Really it is necessary to take down an antivirus? Can you tell me if there is a way to start it again?

Are you familiar with this situation? With Avast, this happens quite often, and here's why. When visiting certain Internet resources, Avast often informs you that the site you are about to visit poses a threat to your computer. In support of its “words”, the system even shows you a banner with a detailed address and the name of a possible “trojan” or virus. And then he reassures you, they say, do not be afraid, the system has blocked access to a malicious site. But in reality it is not so! In 80% of cases, a virus or "trojan" has already "settled" in your system and quickly registered under some harmless pseudonym. (From the author: most of the "trojans" cannot be identified not only by the "teapot", but also by the free Avast antivirus. The maximum that it can do is to catch and kill a few "lousy" "rootkits". You should not blame the weakness of this antivirus : after all, you are using a free version! What do you want for free? Just remember: Avast is far from the best antivirus, especially its free version. Finally, the latest version of Avast often conflicts with the system and blocks many websites that you previously logged into without problems.I will say right away: this report is not "black PR" "Avasta", but just food for thought). But let's continue. Having settled somewhere in the boundless depths of the system, the "trojan" easily and simply blocks the operation of your Avast antivirus, as a result, you are denied access to managing your own antivirus. Paradox? To some extent, yes.

And now let's talk about the main thing: is it possible to somehow push the antivirus off the ground and start it again? Well, you can try: in the end, you will always have time to delete your Avast. So, we perform the following algorithm: "Start" - "Control Panel" - "Add or Remove Programs". In the menu, find your "Avast" and click on the virtual "Change / Delete" button. You will see a window that will display three actions to choose from. Choose the "Update" action. You will see a window in which the update will take place - the download of some file (package). Wait for the download to finish and click on the "done" button. After that, open the Avasta interface and you will see the "Fix" button there. Click on it and the antivirus will work! Miracles? No, friends: you just eliminated the consequence of a system or software failure. However, all the same, I advise you to think about changing the free antivirus: a freebie does not lead to good! At the very least, you can install some other free antivirus and see how it works.

All the best to you and see you soon!

Avast antivirus program is one of the most popular security systems on user computers. Avast achieved its fame thanks to such qualities as low requirements for PC system characteristics and the possibility of using a license for free.

If the user wants to install a new antivirus or decides to erase the Avast program for another purpose, then you can often encounter the problem of incomplete removal, which leads to undesirable consequences and unstable system operation.

Software developers are well aware that the interaction of malicious code with the system begins with the antivirus. The action of most malicious programs is aimed at removing security software or disrupting its operation.

The goal of most malware creators is competition, where the winner is the antivirus software that handles a similar problem and is able to protect its software.

It is because of the enhanced protection that it is so difficult to remove Avast from a computer. The developers overdid it a little, and now the antivirus program is not afraid of the actions of either viruses or users. Problems with uninstallation also occurred in older versions of the program. But, apparently, fearing for the protection of Avast, the developers decided not to fix this error.

Several ways to remove avast from a computer

Method 1: Uninstall software using the built-in uninstall utility - uninstall

The most common way to uninstall any software is with an uninstaller. There are two ways to run it:

• From the folder with the installed program or from the "Start" menu - "All Programs";
• From the Computer Control Panel by selecting Programs and Features.

Managing Windows 8 is a little different. To access the system menu, right-click in the lower left corner. Select the item, as in the seventh version, "Programs and Features".

In the list of software installed on your computer, you must select the desired software and left-click on it, select "Uninstall".

This method is suitable for uninstalling any program. But in the case of Avast, the removal is not complete: files with user settings remain, and in many cases, a running system service is not stopped or deleted. Therefore, before uninstalling, you must disable the self-defense function in the program. To do this, do the following:

1. Go to the Avast user interface;
2. Select the "Settings" menu item;
3. Activate the "Troubleshooting" item;
4. Uncheck the box to deactivate the "Enable Avast Self-Defense Module" option.

However, this does not always give a positive result, as a result of which, after removing Avast, it is impossible to install another antivirus, and errors occur when the operating system starts. Therefore, it is better to use a special removal utility, which can be downloaded from the official website at the link.

Method 2: Uninstalling Avast using a special utility - Avastclear

The creators of Avast heard users in their own way: not wanting to redo the security system of the antivirus program, instead of completely eliminating the problem with removing the antivirus, they created a utility. It is called Avastclear and is able to destroy all traces and remove avast from the computer.

The utility can be launched from normal Windows mode. But in this case, the developers do not guarantee its correct operation. In addition, system administrator rights will be required.

In safe mode, as you know, only the files and processes necessary to start the operating system work, so you do not need to stop the service manually or configure the antivirus.

To remove Avast from your computer correctly, you must follow these steps:

• Download Avastclear from the official website of the Avast program;
• You can run the program, and it will prompt you to reboot into safe mode. However, this will not work if you are not running in administrator mode;
• You can restart your computer in safe mode yourself. To do this, on Windows operating systems of the seventh or eighth version, just hold down the "Shift" button and select the "Restart" item in the shutdown menu;
• If the reboot was launched through the utility, then Avastclear should open automatically;

• You must carefully select the version of the antivirus program you have installed. This will help the utility correctly identify the service and registry entries to remove;
• Also, carefully write down the path to the main Avast folder. If you used the free version and did not change anything, then the path will be the same as in the picture;

As you monitor the program's kill progress, you should see five points of successful uninstall completion:

• Program files;
• Registry sections;
• Explorer extensions;
• Real-time protection;
• avast antivirus services.

If the operation went smoothly, then upon completion, the utility will ask you to reboot. After loading the operating system in normal, operating mode, we get Windows cleared of Avast.

Method 3. You can remove Avast from your computer using the registry and services

As mentioned earlier, a running service and a self-defense module interfere with the complete removal of Avast. These parameters can be edited by yourself. You can prevent the service from starting from the Control Panel. To do this, you need:

1. Select the "Administration" item in the system control panel;
2. Launch the "Services" menu;
3. Stop two running antivirus services;
4. Figure 9. Avast 7
5. After that, you need to go into the parameters of each of the services and select the “disabled” status for them;
6. After restarting the computer, you can safely remove the anti-virus program in the standard way No. 1 described earlier;

Now you need to clean the registry entries from the old garbage. This can be done manually or with the help of special programs. Manually is much faster:

• To launch the registry editor, in the search bar from the Start menu, enter the system command: "regedit";

• In the window that appears, go to the "Edit" menu and select the "Search" item;

• Enter the keyword by which we will delete the Avast records, and click "Find Next";
• One by one, we delete everything that can be found associated with the program.

After this procedure, you should restart your computer. Then you can start installing new software.

It is important to remember that by editing the registry entries and the services that the system starts, you can break the stability of Windows. Therefore, be careful and create a system restore point before any action in order to be able to quickly roll back.

Outcome:

Now uninstalling any antivirus or other program will not be a problem for you. The best way to remove Avast from your computer is to use a special utility from antivirus software developers. Therefore, if there is an opportunity to access the Internet to download the Avastclear program, use it.
