It's also possible that the last update to McAfee was bad so the next one sorted it out. Instances of these 'false positives' are less than they used to be but every AV program gets them once in a while !! As for running virus scans multiple times, if the first scan picks up a lot then yes it's definitely worth doing another one and there's a case for repeating until you get a virus free scan. -- Best regards, Barry mailto:barry@yobunny.co.uk MicroSoft Free Zone running Ubuntu 9.04 'Jaunty'
