As Avast is an internet-based application that you have to download and then install, corrupted files could be behind the reason as to why it might not open. Though thankfully, Windows offers a built-in tool that you can use to scan your PC for any corrupted or missing files.

This ends up becoming a major reason as if the files are not complete, the program won’t be able to work or open properly.

Just Press Enter and the tool will start its work.

This is a common problem that people run into. Especially because of how we are always connected to the internet. And so some virus might have come through to your PC or Laptop too.

Though Windows does not offer a specific tool that you use for this problem, there are numerous tools present on the market today. But out of all of these, we would recommend for you to use the FixWin Tool for Windows.
