It is nice that this isn't a false positive, but avast isn't removing the threat completely, it just keeps jumping and then reappearing. I've had it pop up about 30-35 times today (at least) even though I get the "threat secured" message, it will just reappear 5-10 minutes later. I don't have my web browser open, it just pops back up.
I'd love to just kill it and not worry about it, rather than have the harsh warning dings every 10 minutes warning me about the threat - even when I'm not using the machine, it's just sitting idle.
