On Sunday an email with a link to a porn site was sent from my hotmail account to all the contacts I had in that account.
I'd only been using this laptop for a few days (it's my old one, my Dell died) and didn't have any antivirus software running, but did have the windows firewall up.
I've since downloaded and run AVG and Avast antivirus software and SpybotS&D but they didn't find anything nasty.
Do I definitely have a virus? Why hasn't a similar thing happened to the other hotmail accounts I've been using on this laptop?
Hotmail support gave me a pretty standard "change password, update antivirus software" response.
Any advice appreciated.
