I've had the popups blocked on Saddo for a while, as I was sure I got a virus from one of them in the past.. Havn't had a problem since I did that though, so all is good..

As a side note, I posted the below link a while ago on here when I had to fix a virus on my Laptop.. It was very stubborn and none of the things i'd just heard about here and there worked, but then I found this link and it cleaned everything up... I've since had to go through the process 2 or 3 times for things that have gotten onto various computers and it has always cleared it up..
There is a bit of work involved as you run about 5 programs, but you can see that every single one does it's job and they all work together to get rid of ANYTHING that shouldn't be there...

Anyway, have a look if anyone has any problems with virus'
