Hello,
I'm having a ready odd problem I just cant seem to fix on my own nor find a fix, I read about almost everything and looked up everything, I did a fresh install of windows to get my pc fixed since it was just time for a update and new start. So I tried to download avast and find that it start to download then just disappear, I tried to run as admin same problem, tried to uninstall as well as admin with it same thing starts then disappear, i cant find it on my PC anywhere, the only trace i have of it is temp for some reason all the download goes there noting else gets added at all I really don't know what to do next I'm going to go to my HWID keys and delete that but as far as i seen it does not help me much everything else downloads fine just avast has this problem.
