The essence of the problem was that the Avast user interface does not open, or rather the error Ui failed to load appears instead, or sometimes just white screen. This applies to all new versions, including the most powerful Premier. The incident mainly affected devices running Windows XP and Windows 10 operating systems. Service employees technical support They unanimously recommended deleting the application using the Avastclear utility and reinstalling it. But this method did not help. A little later, the developers announced that it was necessary to perform special settings on the computer: start the background intelligent transfer service and the terminal service.

Important! Before purchasing any software, experts advise testing the work trial version on a computer, laptop, tablet or smartphone.

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

One of the most common reasons why it won't start antivirus protection Avast is to disable one or more program screens. Disconnection could have been made by accidental pressing, or system failure. There are also cases when the user himself disabled the screens, since sometimes some programs require this during installation, and then forgot about it.

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

To fix the problem, right-click on the Avast icon in the tray. In the menu that appears, select “Manage Avast Screens”, and then click on the “Enable all screens” button.

After this, 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 turn on antiviruses on it, including Avasta. 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 for and remove viruses, you need to use a utility that does not require installation, for example Dr.Web CureIt.

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

Avast critical problem

Of course there are problems at work Avast antivirus happen quite rarely, but nevertheless, due to a virus attack, power failure, or other significant reason, the utility can be seriously damaged. Therefore, if the first two methods of fixing the problem that we described 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 completely remove Avast antivirus followed by cleaning the registry.

Then, install the Avast program on your computer again. After this, startup problems, in most cases, disappear.

And, be sure to remember to scan your computer for viruses.

Operating system failure

Another reason why the antivirus may not start is a malfunction 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 of occurrence and the depth of damage to the OS.

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

As you can see, the degree of difficulty in solving the problem of the inability to run Avast antivirus, first of all, depends on the causes, which can be very diverse. Some of them can be eliminated with literally two clicks of the mouse, while to eliminate others you will have to tinker thoroughly.

Hello, dear friends!

Today we’ll talk about the free Avast antivirus, or more precisely, how to fix the problem of starting it. So!

The other day I received a dozen emails asking for help in eliminating the following problem with this antivirus. I quote: “Hello! I have this problem: I’ve been using the free Avast antivirus for several months now and everything has been fine. but three days ago I ran into a problem that I still don’t 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. I hovered the cursor and saw that the system was not protected. When I try to start the protection, nothing happens! That is, nothing at all! I already rebooted the system ten times, and manually turned something there - zero! What to do? Do you really have to take down your antivirus? Tell me, is there any way to start it again?”

Are you unfamiliar with this situation? This happens quite often with Avast 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. To confirm its “words”, the system even shows you a banner with a detailed address and name of a possible “Trojan” or virus. And then he reassures you, saying, don’t be afraid, the system has blocked access to the malicious site. But in reality this is not so! In 80% of cases, a virus or Trojan has already “settled” in your system and quickly registered itself under some harmless pseudonym. (From the author: most “Trojans” cannot be detected not only by the “teapot”, but also by the free antivirus “Avast”. The maximum that it is capable of is to catch and kill several “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. latest version Avasta often comes into conflict with the system and blocks many websites that you previously accessed without problems. I’ll say right away: this report is not “black PR” for Avast, but simply food for thought). But let's continue. Having settled somewhere in the endless 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.

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”. Find your Avast in the menu and click on the virtual “Replace/Delete” button. You will see a window with three actions to choose from. Select the “Update” action. You will see a window in which the update will take place - downloading a file (package). Wait for the download to complete and click on the “finish” button. After that, open the Avasta interface and see the “Fix” button there. Click on it and the antivirus will work! Miracles? No, friends: you just eliminated the consequences of a system or software failure. However, I still advise you to think about changing a free antivirus: freebies do no good! At least you can install something else free antivirus, and look at his work.

All the best to you and see you again!
