I'l make this simple as possible... If any of you guys use MSN or MSN chat rooms DO NOT, I repeat DO NOT click on a link saying..."Is this your photo?" It will then link up to a website that asks you to download a .PIF file but appears to be a DOS file at the same time through the logo that appears when downloading through Firefox.... It will unleash plenty of viruses and trojans...whilst passing the link onto all MSN contacts whilst trying to activate the icons/software it places on your desktop/system. My mother did this earlier on this evening and I spent 2 hours trying to clean the viruses of the system and I still haven't gotten rid of it all yet. And its managed to disable virus protection at the same time. Beware!
