Now I think its returned!! My firefox takes me to the pages it wants me to regardless of what link i click on. Iv tried to save a hijackthis log for you guys to work with but unfortunately i cant seem to do it. the overall performance of the comp is also starting to be affected. The only info i can give now is that there is a unrecognised startup entry which has been added (not by me) which was not there before and even if i delete them they keep coming back.
somebody please help!! this is soooo annoying!!
