About 2 weeks ago I got BT broadband Total, installed it on my laptop, and removed the freeware virus protedtion I had (AVG, Zone Alarm etc), in order to install Norton Protection Centre. All was fine unitll a day or two after when my cpu started going up to 100% and slowing my laptop right down. Also when I rebooted it took ages to startup, and the windows tune that plays on startup was all dodgy. I figured it must be some kind of virus so I wiped the system (I actually wiped it, not just created another partition).
All was fine unitll last night, now my laptop is doing exactly the same thing as before. I think that means I can rule out viruses etc, unless there are any that can survive when you wipe your system. PLus i have run a full system scan with norton, and with a squared, both were fine (well, asquared came up with a few medium risk entries for shareaza, but I don't think that's anything to worry about). I don't really know where to go from here, if anyone could help I would be eternally gratefull...
