Today I noticed that my computer is temporarily freezing or lagging every so often but only when it's connected to the internet, this can get mighty annoying especially when trying to listen to music and stuff. But seen as though this only occurs when I'm online it strikes me as a possible malware problem (I've already reinstalled the drivers for my network card).
Anyways so I have been searching for the answer everywhere, I have already run scans with adaware, microsoft anti-spyware, ewido, trojan hunter & fprot.
Usually I wouldn't post but I don't know what else to do.. anyways here's my hijack this printout, any help would be great:
