lol fu! I just said it reminded me of that! I had big fight with that thing 2 years ago when I was in italy.
I called it IP Virus. It attacks your IP I guess.. every time when your PC is plugged on NET cable porns start popping up! Sites in browsers,shortcuts on desktop and stuff.. and you cant do nothing about it but to plug out the cable!
and some "badass" antiviruses like NOD&AVG blocked my net so I couldnt download new antiviruses. So I had to let my PC unprotected. Oh yeah,and AVG crashed my Windows XP Home!
Used every damn antivirus on the planet but nothing worked except avast&PC Tools later!
also made some good money with that!
So I suggested him similar process I did..
