Please describe what your son started to type and the characters which started to appear. Do you have the other Microsoft Office components istalled - e.g. Word ? What is "any other program" ?
My son's computer is running WIN XP. Each time he starts to type a message in OUTLOOK other characters start appearing besides what he types. Norton's anti virus found nothing. I put AVAST virus protection on and it found 3 viruses but the problem still persits.This only happens in OUTLOOK and not in any other program. Has anyone got an idea? Should I try to remove OUTLOOK and reinstall it?
