Hello,
Today, July 22, 2012 my avast went crazy, literally, he began to erase all my files on your computer, from scratch, even the ones I've used a lot of time and that has the greatest chance of being infected, I I had to disable it temporarily to not have major damage.
I'd like a solution as fast as possible economies, because I do not know what to do.
I live in Brazil and speak Portuguese, and do not speak or understand English, I made this text with the help of google translator.
Thank you for your attention and look forward answer as soon as possible.
Note: I've upgraded to the latest version 7.01456 and it's still deleting everything in sight, help.
