I havent used Avast personally for a few years but I have it installed on our Family PC and I just now tried to install on my sisters recently bought Windows 8 laptop, It installed fine but I didnt see the yellow ball in the tray icon so I tried to open it by clicking on the desktop icon and I got an error that something wouldnt run so my question now is it actually compatible or should i wait?
P.S. The recently bought computer didnt come with a pre installed AV, only Windows Defender.
