3. Process Trust Error During Avast Installation
This error message sometimes appears when you’re trying to install Avast on Windows 10.
Namely, you’ll get Process Trust fatal error pop-up message saying Avast doesn’t trust Avast Installer. This means that you cannot install Avast on your computer.
This error appears due to a conflict between Avast and your current antivirus program. So, just disable your current antivirus (in most cases this is Windows Defender) and try to install Avast again.
This time, you shouldn’t experience any problems. This error will remind you that having two antivirus programs installed on your computer is not a good thing.
