Recently my system got infect with some spyware which kept displaying popup ads and also changed the desktop background to blue color that said 'Your sytem is infected with spyware and click here to download anti spyware software'. Ofcouse I restored the system using acronis image.
I haven't downloaded or installed any software from the internet. I visited some random movie site with lot of popups etc. Just visiting the site infected my machine (xp prof sp 2). All the ports in the firewall are closed except 13000 port which I use for azureus. ( I didn't have antivirus when it got infected)
Could some one please tell how the spyware got installed without my knowledge? I was thinking that I need to install some software and that secretly installed spywares like Kazaa etc.
