I did. It took apart my Spybot Search & Destroy program by identifying it as a “virus”. I tried reinstalling Spybot and Avast wouldn’t let it even download the new copy.
So I uninstalled Avast and replaced it with AVG Free.
I tried reinstalling Spybot S&D but their site is so busy I couldn’t connect. Looks like Avast knocked out everybody using Spybot.
I may go back to AVG until Avast gets their act together.
If you get a false positive, you can usually just wait until the next set of definitions are available. If an antivirus is flagging something used by a lot of people, they will get new definitions out pretty quick.
I had this problem with AVG and iTunes. They had a new definition out in a couple hours.
