I have a (medion) laptop pentium 3 which run xp and nortons antivirus. Dont ask me any more specifics. When i open a window with a dialogue box and place the cursor in to the box, text or words appear. This also happens if I open a word document and not online. The words are rendom which include symbols and numbers. I have just run various spyware which although has found various rubbish it has not solved the problem. Any ideas folks?
