I recently got a new laptop, Acer Aspire v3-771g, and clean installed windows 7 home premium 64bit on it. While downloading other programs/video games, they all suddenly stopped, with a download speed of 0kbps. The strange thing is that I feel there is something stopping it because while torrenting, the torrent will download for a few seconds then says "stopped", and if I right-click it and click start it downloads fine. Another thing is that it doesn't happen right at boot, I can download fine for about an hour or so after a restart, then I receive this problem.
Lastly, it is possible there is a virus because I surfed the web and downloaded items while I didn't have any antivirus software but I did two scans so far, one on MSE and the other on a licensed version of McAfee, with the result being there is no issue. Is there another free AV that someone could recommend me trying?
