Avast software developers are constantly working on improving the source code, making edits, and optimizing its work. However, it is impossible to foresee everything, and often incidents occur with the antivirus. Today we will talk about why Avast does not work and why the problem called “Avast scan failed” occurs. In the course of the story, we will look at common causes and methods for solving the problem.
The Solution to the Problem
There is information on the web and on the official technical support website regarding problems with the popular antivirus. The most common of them are offered to your attention. For ease of perception, we will divide the further narration into several logical blocks.
Deactivate Protective Screens
Often the problem lies in the intentional or unintentional disabling of one or more of the protective screens. Therefore, the functionality and effectiveness of the program decrease to critical indicators. To solve the problem, you need to do the following:
- Move the cursor to the tray and right-click on the characteristic orange and white icon.
- In the context menu, open the “Protection” menu.
- Here click on the “Main components of protection” tile.
- Activate all functions.
The main sign of the destructive activity of viruses is the inability to open any anti-virus software installed on a stationary platform. Also, if Avast can’t scan something, it may be the result of viruses. The only way out of the situation is to download utilities that can scan the system without prior installation. For example, this can be Dr.Web Curelt. Upon completion of all procedures, Avast should be operational again.
The developers are constantly working on improving and optimizing the Avast source code. But the probability of a crash of the system cannot be completely destroyed. If the use of the previous options did not bring results, then use the following step-by-step instructions:
- Go to the Control Panel and open the “Programs” item.
- In the list of preinstalled software, find the antivirus and remove it from the PC. You will need to confirm the seriousness of your intentions several times.
- Go to the official website of the creators and download the latest version of the program.
- Activate it and reinstall Avast.
This situation occurs less often, but it will require much more energy and time. To solve the problem, you need to start the procedure for rolling back the operating system to the last restore point. The instruction for this operation can be found on the official website of developers.
Let’s Sum Up
There are many reasons why Avast does not start and ignores the performance of its direct duties. Or it can even stop scanning the whole computer or its separate part. In such cases, applying an integrated approach will make everything work perfectly and gives a 100% probability of success.
