not sure if starting tens of topics not Avast related,and not security related even in the general topic section is quite acceptable here. Yezinki, use Google sometimes and better, go to the appropriate forums to ask your question, each software company having its own forums generally. I mean this is no computer course section, if you go on that way and if the admins here just let go as usual, this section will be filled up soon with stuff that doesn't interest people who came to talk about Avast and Windows security in the first place. I mean seriously you can't ask here for help about every single detail that you don't understand in Windows and third party software.
