Lately I’ve found that my system becomes almost completely unresponsive when avast is scanning something, whether automatically or via a scheduled scan. This is particularly annoying when trying to download something in firefox/steam or copy files to/from a flash dive. Avast also seems to scan folder contents when opening a folder, even if it has already scanned them today, which takes folders forever to open.
I’m running this on Windows 7 Pro x64, 6 GB ram, Pentium D @ 2.4 GHz. I don’t have any other AV programs installed, as I’ve seen what happens when you have more than one.
This problem has slowly been getting worse on me for about 2 months, and the other day it finally irked me enough to post this.
well…i have no idea why : guess i would try a reinstall and see if that help
remove with the uninstall tool and reboot…
install again and reboot… http://www.avast.com/en-eu/uninstall-utility
OBS: i guess this is a very new machine ?
did it come with preinstalled AV ?
did you use a removal tool to clear any leftovers after uninstall ?
No, this is not a new machine. I build it about 4 years ago, and upgraded to Windows 7 about 2 years ago. I’ve only ever used Avast on my windows 7 install.
::Followup:
the uninstaller did its job. Everything sped right back up again without Avast. It bogged down again after I reinstalled it though.
I assume you cleaned up (or, like me, never encountered) that bad-defs problem from last week? One of its characteristics was that one of avast’s services used so much CPU that nothing else could load, including most of the rest of avast and the firewall.
Had you altered and of the default setting’s inside avast? namely ticking the scan all files box in scan when opening \ scan when writing under the file system shield setting’s.
I don’t remember changing any of the settings, other than disabling sounds, but that shouldn’t make a difference. The problem also seems to have gotten better over the past few days, and I can’t seem to find any reason why it changed. As long as it’s better, I guess it’s fine.
