Sorry, I'm not very tech savy, but when I was updating the Spybot on my mother's computer, it started having registry changes about 1/4 of the way in. It seemed normal enough (I don't use Comodo personally as it's far too picky), so I allowed...and allowed...and allowed...it just kept going for ages asking to alter things, and whilst I'm not sure of the directory (memory lol) they did end with website names. I started blocking half way through as I got uncertain of what I was doing, and cancelled the update entirely shortly thereafter.

Is that sort of registry change common when updating Spybot? If so, is there a way I can have Comodo allow that program to make registry changes and un-do the blocks I've done? I'm not quite sure what I've done, and I'd rather not have to re-format my mum's computer due to me allowing virus' or stuffing her scanner. Cheers.
