kawecki .... "I don't use firewall, have no active antivirus running" No disrespect here. But thats what I call self-inficted. I spend a lot of my time cleaning spyware and viruses from home user systems. XP is particulary prone as SP1 leaves messanger on as default, and that can easily call a webpage with a hidden dialler. If you need help to remove the nastys, try this 1st. Get yourself Ad-aware SE, Spybot Search and Destroy, and AVG. Then once your clean get zonealarm and panicwares pop-up killer. They are all free.

Pinky - you left the lens cap of your mind on again.
