Virus alert

What a day.
Tried to download a manual for a tumble dryer I've been given and I managed to get a load of rubbish on my PC. Deleted everything I could see that had installed but the darn thing had infected my PC.
Spent an hour with geeksquad remotely linked to PC fixing it for me.
Soooo annoyed that I did this. I'm usually so careful when I download stuff.
