i'm gonna start by suggesting that this is your problem. then i'm gonna ask a bunch of questions

1: whats the specs? OS and service pack
2: are you behind a filter or firewall? (at school/work for example)
3: are you using a real-time scanner like AVG? if so, which one?
4: have you run a MBAM scan?
