it looks like gate1975mlm and others who are using machines with CPUs newer than mine (and have IE7 final rel. + Spybot 1.4) have the SDHelper problem.
streetwolf, what kind of computer were you using when you had the SDHelper problem? as I told gate1975mlm, list the specs of your computer here.
same thing for you, jchopick. give the specs/details about your Dell machine here.
