any suggestions? to add, i havea a virus scanner on here, it cant be loaded with any other scanners, its called Charter High-Speed Security Suite http://charter.com/products/highspeed/services/security.aspx
this is a good anti virus it removes almost anything trojans all that bad stuff that can harm your computer, its only the 30 day trial buts its worth a shot. http://u4.eset.com/eval/win/v2/nentenst.exe
More info would be greatly helpfull. i.e. Itunes version, age of some pc hardware, very impotantly when is the last time regular maintenance was done(like blowing it out), etc
