Virus or Trojian

Hi. I’m working on a Dell, running xp and the symptons are sluggish (virus) and the \\\\ is constantly being inputted all by itself (trojian /Hijacking) I have run AVG 8 along with Ad-Aware with the only thing being found were cookies. I restored the laptop back to a way earlier time, and most of the day yesterday, the \\\\ did not bother me, however at the end of the day they reappeared and that was after I ran a mcafee on line scan.

I noticed these .exe’s running in the task manager, I am not sure if they are the cause or not.
dlg, dsagnt, mdm, bcmwltry, wltryswc, hkcmd, alg, pcmservice, wmiprvse.

I had just downloaded AVG 8.

Any help on what to do will be appreciated.
