INFECTED WITH TROJAN HOSE GENERIC 18RUJJ

I seem to have a virus. Every 5 minutes or so the wave volume is muted, there are constant clicking noises and audio adverts for cleaning products. Occasionally Internet Explorer pops up with adverts, even though I never use it as a browser. I'm on Windows XP. Please help.
I ran the Malware scan it gets deleted, but reappears on REBOOT.
