After updating the the most recent detection files today I'm getting an error saying there's problems with Trojans.sbi during scanning. I've got the same error on two different PCs too, just wondering if it's purely a one-off problem with detection files (i think i updated both PCs from the same source, safer networking usa something or other, though i did download updates from official site and manually install too) or a bigger problem.

I'm kinda concerned cos I've just had one PC infected with a lad of trojans and I've been scanning / cleaning it with everything I've got / hadn't got. As always, spybot found the most problems but i'm just worried it might be missing a few...
