anybody hear of NT Authority??. a friend of mine got hit by them & couldn't load xp back on system. found out his bios had been changed( board is Asrock p4vt8+, bios date dec 30 2003). checked Asrock site earliest ver1 came out 2004/02/26 not 2003, so reflashed his bios upto v1.5 but still can't load xp but can load win9x no problem. he is going to save his info on another drive than blow main drive out & reload from scratch xp & it is not a virus as nt authority predates blaster by a couple of years & he ran stinger, avg6 & an online scan with no viruses found
