Hi I am running on Win 7 x64 since 8 month. Everything was fine until 4 days ago...Since then my internet connection comes and go... It's hard to explain...but all of a sudden my browser lose connection and I can't connect with either Messenger or Pokerstar for exemple. As if I've been disconected. The wierd thing is sometimes it comes back for a few minutes...then again goes away... It may be a trojan of some sort since I did used some "dangerous files" recently (I know...I should not). But i did run a AVG scan and...nothing... I use a routeur/box connected in LAN but I don't think it has anything to do with the problem because for exemple if I lanch a download.....it won't cut the connection...no matter what....during the time of the download....but after some period of inactivity or if I'm just browsing....I lose the connection. If anyone has any ideas....This is driving me crazy. (Note: after a reboot the connection always works again). Thanks in advance!
