There are a huge number of people out there who, having bought their computer with pre-loaded/installed software, are quite happy to assume that it is protected and have never updated anti-virus or their fire wall.
Plus remember that you are not protected for the newest virus's untill the anti-virus companies can write the latest patches.
Your anti-virus is only as good as the last update.
Well my AV updates automatically so I don't think about that but as for adaware, spybot etc, I do them whenever I'm gonna do a scan, not every day, sometimes only once a week or so. So when I see a post for updates it reminds me to do it which is handy as I'm a bit forgetfull. Anyway I like 'em, so thanks to you that do 'em :o)
Yes Mango they should.... but if you notice most regular posters only use their computer to come here (when site goes down they display withdrawal symptoms :o0).... does not leave them much time for anything else!
