I suppose it all does depends on what you use a pc for, if your a gamer or into video editing etc then youd want to update really, if its just internet browsing etc then youll probably be fine.........keeping it virus free of course lol.

The sasser virus came about in around 2004 mate, to be honest it shouldnt effect newer operating systems as it exploited windows xp and 2000, its a worm virus that exploits and spreads via a network port, its actually an out of date virus thats easily sorted by todays virus software.........make sure you update your definitions on a regular basis mate.
