Thanks oldbob.
I have no problems updating the NAV definitions online and they will be available until my present NAV subscription expires on 7 April 2006. What I meant was that I cannot take out a further AV subscription to NAV 2002 as Symantec no longer provides AV subscriptions for this version - in effect, I cannot renew it. The only option shown on the Symantec website is to update to NAV 2006 via an online update. No doubt you will not come across this yourself until your present subscription expires.
I would normally agree with what you say about the need to pay for quality. The trouble with this is that there are loads of postings on AB and other forums from NAV users who have migrated to AVG and have said how much better it is at both detection and removal of viruses. AVG has obviously got something going for it. To make matters worse, I'm surrounded by many highly qualified computer technicians here at university who have said they use AVG at home in preference to NAV or McAfee and it has never let them down. Personally, I can only keep an open mind as I've not used AVG previously.
I think you're on the rigt track with your suggestion of uninstalling and custom reinstalling SystemWorks. I'll give it a try when I get home.
Thanks again.
