ok... i just went to change my security in xp from simple to advance (disabled the private folder crap) and i found out that about 10 of my files in my G driver had a new user name ...(S-1-5-21-1085031214-1078145449-1708537768-1003)... apparently, the hacker took ownership of my files and when i tried to delete the user name, it told me that it was inheriting permissions.... now... i would like to know what should i do... i already have reverted my files permissions back...and i want to know how they hacked me and what should i do to prevent them... i dont have firewall or virus protection yet... but this will make me go get a copy ... also... can i use neotrace to track down this bitch? does it help if i get his ip number and hack his comp back? ( i used to play around w/ hacking so i know a little bit...hehe...) so what should i do now?? any advice is welcome!!
