Come on the computer as the ipad is being slow but logged into mums log in as mine never worked again after the first set of trojans a while ago. I'm being followed by a box that says open mcafee security center but it isn't telling me there is a virus which it would do I think. The box is doing my head in. Apologies for any spelling errors the writing goes behind the box when it gets to it so I can't see it. Any ideas how to get rid of the thing.
