Hello! I have installed avast! 4.6 after installing my operating system (Windows XP Proffessional with SP2). If I run a game, or another application, after closing it, all of my web browsers stop connecting to the Internet - and I mean when I enter the browser, I can't visit any page at all, it's like my connection would be inexistent. The same, if I disconnect my instant messaging program, I run another application and then I try to reconnect, the IM program doesn't connect. I must log off Windows and then log on again, to use the web browser or the IM program, or I must give the computer a restart (both work the same). I wonder if this is because the antivirus' firewall or because the antivirus itself. I have never used avast! before therefore I think this might be the problem. Please, give me an advice or some indications because it's really nasty to log off and on before start using the web or chat after a while. Anticipated thanks and sallutations to the avast! team. Yours faithfully Charmy.
