Well, he wanted the computer back asap and as it was a Sunday afternoon I didn't have the time to research fully. He originally asked me along to see if I could sort out those annoying messages that had been telling him (for years, presumably) that his computer 'might be at risk'. I knew enough to avoid Norton and McAffee for someone who's not very technical though! Scan now completed and reports no infections - incredible! £25 a year doesn't seem too bad and at least he's protected now.
