I would fix your machine rather than go to another AV. You can try REVO uninstaller to make sure everything gets completely uninstalled. then reload Chrome, then download Avast. Maybe you could also restore to an earlier time. I don't know what is going on with your system, but I've never had to stop Avast temporarily except for running Combofix. And even then, it has always come back up fine.
A few days ago I disabled Avast temporarily to install something, restarted computer, and since then Avast is blocking Chrome.
I can only run Chrome if I disable Avast. Tried unistalling/reinstalling both Avast and Chrome, no luck. Also tried tweaks like disabling sandbox.
IE 8 works fine btw, but I'd like to get back to Chrome.
So now it's time to try another AV. But it has to be light on resources as it's for a 1 GB netbook. Any suggestions?
