I noticed the latest version of avast is freezing my system. I believe it is caused by the combination of avast and the latest NVIDIA video drivers, but I cannot be sure. I have version 62.20 of forceware drivers [while I know it is a beta version, I think the 61.77 are final, and they have the same problem]. The problem happens on another system too, so it isn’t a system specific… I haven’t seen this problem with early 5x.xx forceware drivers. Any suggestions?
Avast and those Nvidia drivers work fine. So it is not just that combination. Could be in combination with other drivers/hardware. Check the event and system log for errors. If there are any us www.google.com and the Microsfot knowledgebase to solve them. See if it still happens then.
Besides this here are other things you can try:
- Disable all applications from loading at boot time, leave only Avast there.
- Check the temperatures of your case, cpu and video card. (make sure ALL fans/coolers are clean)
It works fine 90% of the time… but sometimes [when right-clicking on the desktop, or on a movie [specially from anetwork place]] explorer.exe keeps getting frozen… [the mouse turns to an hourglass and stays that way]. Plus, the other computer has a differnt motherboard, video card, and RAM & CPU… and it still does the same thing…
What are your settings of the Standard Shield? In particular, is the Advanced option “Show detailed info on performed action” turned on?
“Show detailed info” is off.
All other settings are default [just like a fter a fresh install] → I haven’t touched anything…
Does it help when you stop the resident protection of avast? (especially the Standard Shield)?
Yeah, if the protection is stopped [standard shield], everything’s ok…
Ok, for me vsmon.exe (a ZoneAlarm Firewall 5.0 module) was consuming 90-100% of CPU cicles… I did not try the latest version (5.1).
Do you have any trouble with your firewall?
Do you use a proxy filter?
What I have in startup is Spybot TeaTimer and I also have SpywareBlaster… I’m gonna try removing TeaTimer from startup…
Ok, maybe TeaTimer but I really think it’s not related.
Did you empty your C:\Windows\Temp folder?
Are you scanning large archive (.zip) files?
Temp is empty.
And… the problem occurs on right click on desktop, so no zip either…
Open MS Config and temporarily disable ALL non essential programs and then reboot and see if your problem is gone.
If it is, then it’s one of the toys that boot at startup. There isn’t any fast way to solve that problem but, start by re-enabeling one add on program at a time. Run your system for a day and and another one. Keep doing this untill your prob. reocurrs and the last prog. you added, would be your culprit. ( I just went thru that 
)
Have fun…
