i have this problem, yesterday my antivirus found this virus, i think i was a worm, and told me that the file could not be repeard. i located the file, but could not delete it. since then, my computer puts on this message telling me that it is going to be shut down. this doesnt happen all the time, other times the turn off button desapears, or internet explorer goes crazy and is terribly slow. i tried to go to the norton or mcafee web pages, but i just cant get in, im directly sent to some page called interent optimiser, i dont know what to do, please help.
