Thanks for the super quick response Terry!
Bear with me...I'm not hugely technical
I think by anti-malware programmes you mean something like Norten Security? if so, then yes, it scans my computer each night but I haven't had any messages from it indicating a virus or anything like that.
I didn't do a 'repair' installation...I just scrubbed the programme off the computer and reinstalled - I'll put the CD in now and see how to do a repair installation but I'm not sure how to do a reintsallation of the patches...can you explain a little on that at all?
thanks again Terry
