My best friends younger brother (14-15) was trying to be a scriptkiddie/hacker but everything he downloaded had a trojan or a virus in bedded in it. We ran Norton Virus scan on his computer he had 5 trojans 3 viruses of various types. An one of the was a back orfice trojan which allows someone complete control of your computer remotely. We had to fdisk and recreate the partitions it to get it off there a normal format wouldnt do it. Now he just downloads mp3's and pron. =)
