please help me as my puter is running slower than normal. the main problem is that i can connect to the internet and surf the web for a while, but then all of a sudden internet explorer cannot open up any more pages. however, msn messenger keeps on running fine. my avg antivirus detected the trojan IRC/BackDoor.SDBot.54.X in the file windows/system32/regscan.exe, but cant remove it...how do i do that?

i have also included a hijackthis report:
