My Avast Premium Security recently disappeared from my computer. I still see it in Settings – Apps and Features but I cannot start the program or unistall and reinstall it. I am getting the following message: “C:\Program Files\Avast Software\Avast\setup\Instup.exe” not found.
I found a forum entry recommending removing the damaged Avast by Avastclear and reinstalling. I downloaded Avastclear and tried to run it (with Admin rights) – it pretends to be starting for a few seconds but then nothing happens. I also tried to first independently start Windows in safe mode and then run Avastclear but also nothing happened. I could not find any hints online on how to proceed with Avastclear not working.
Please help me get my Avast Premium Security back up and running correctly.
Did not work. I downloaded it and ran it. Similarly to Avastclear, it pretends to be loading for a few seconds and then nothing happens. Can something in my computer be blocking these in without notification?
OS: Windows 10 Home, version 21H2, build 19044.1466, 64-Bit
No other security software installed. The computer (bought fall last year) came with McAfee pre-installed which I immediately uninstalled and replaced with Avast. All worked fine until mid February.
