A few months ago I had a problem on my PC, I posted on here and some very kind people pointed me in the direction of a website where I was able to 'clean' my system.

Well I think it's back, my Norton Antivirus keeps popping up and e-mails are being automatically sent from my BT account, at one point I had 28 e-mails outgoing, none of which I wrote. And now my PC has really slowed up when online.

Somebody please help. As I cannot refer to my previous post as it was lost.

Thanks in advance.
