I downloaded some freeware progs. last night from a reputable site (Sofotex) & one of them had 'Incredifind' spyware loaded into it.
Anyway, Norton did a good job of drawing my attention to it when the little terror tried to connect to the internet. I subsequently located & deleted all the offenders.
Tonight I find various oddities going on with the pc such as programmes not responding, autorun not working & consistently, a prog. called 'wupdater exe' running in the background when I've shut down the pc in order to 'GoBack' to a time pre Sofotex downloads.
What is 'wupdaterexe'?
Eventually a GoBack was succesful & all is well again.
