on my dad's (honest!)...he's old...pc, he operates windows xp home edition.
when logging on to the net or outlook express an application error with something like 'windows/system or application error, or problem with writing memory...stuff like that apprears in a warning pop up. it then gives me...sorry my dad..60 seconds to close any programes, then shut down and re-boots pc.
i guess this is a virus which has infiltrated the pc since he last updated his virus definitions? but as we can not get logged on to download anything we are stuck.
