and lastly sometimes my AVG icon on the system tray hides away does this mean it is still active or inactive?? or it is okay to be doing so, thanks.
I replaced AVG Free by Avast! on my mom's computer because AVG seems would crash quite often, with no error message. It definitely wasn't under the ``show hidden icons'' button in the system tray. Sometimes it would disappear when the computer was running, and sometimes it would just not start at start-up. Sometimes daily scans were missed because of this problem, I think. Mom did learn to double-click the desktop icon to restart AVG, which seems then would be fully functional (one of the nice things about it, you didn't have to restart the computer). I am quite concerned that there might be malware causing this problem, although I can find no sign in Hijack This, and the need for a memory upgrade could partially explain the computer's slowness.
The downside of Avast! free edition is that there seems to be no way to set it to do daily updates and full scans automatically (or is it doing updates but not scans--I forget at the moment). The on-access protection starts automatically, but the scans have only run when I went there. Fortunately it isn't finding anything, because when Avast! finds something it suspects is malware, it requires operator interaction to continue the scan, and the scan usually doesn't finish before I leave.
Edit: Split topic into it's own thread per request, to more easily address the issue. ~ Animal
