I recently downloaded some music through torrents, and that's around the same time I started having problems. I'm running XP. Almost everything is okay, but I can't sign into msn or access my email (hotmail.com/ windows live), and it does seem that the internet is a bit slower. I ran a virus scan with Kaspersky, but nothing of interest was detected. I'm also having trouble connecting to the internet on my xbox 360, and my sister cannot get onto msn on her computer either, which is on the same network.
What should I do to get rid of whatever is causing the problems?
Whether it is related to the problem or not, what are some good anti-spyware programs I can get for free?
