Any upgade that would gobble all my CPU

[tom.green]

Suddenly, yesterday, Avast started eating up all my CPU. It was so bad I could would watch mouse moves delayed by 10 seconds! It took me 4 hours to find it. The only solution was to disable Avast.exe at startup in MSConfig and reboot. When I then tried to configure Avast it restarted the process and gobbled up my CPU again and I had to do it again. My machine was completely unusable.

This just started yesterday. Did something change? Is there some horrendous bug in an update?

Avast version 2014.9.0.2021 free version.

I had tried Kaspersky before. I think I get rid of everything except maybe some registry entries.

No, I didn't install anything else recently, nor since. And the problem was happening before I had started any applications, so I don't think it wasn't anything else. Anyhow, stopping Avast solved the problem.

Weird: Now it is working fine. I'm not sure why, but I did uncheck all 3 options under Active Protection. I assume that there was some bug in one of the Avast updates that was causing the problem, and that was subsequently fixed.

Anyhow, I guess it doesn't matter any more. Thanks for following up my message.

Which options Doing this can leave you without protection.


There may be leftover items from Kaspersky unless you used their removal tool:
