Avast told me that a browser add-on had a bad reputation (Crazy Mail in Google Chrome browser). So I had that add-on removed by Avast. And yes, removed it was, but also, as a result of Avast's action, I lost my browser session, with about 15 open tabs, with 5 fixed tabs amongst them! NEVER I will let Avast do this again, NEVER! I really can remove an add-on by myself, in a far better way, without destroying my session!
Also, adding to grief, I could not even use my regular e-mail address for creating an account, just for having this topic posted. It was stated that the e-mail address was already in use. OF COURSE that was the case, and I knew that: it was already in use for having registered the program every year again, and WITHOUT having an account already! So, stupid enough, I was forced to use one of my other e-mail addresses for creating this account!
