Hello, This file.. c:\WINDOWS\system32\ptjsbfbyth\lsass.exe I had to delete it because it contained a trojan virus and now i am getting errors when windows starts up for me because it cannot start this file,.. i checked in my startup in msconfig, and this file is listed twice. the location in msconfig says something about windows NT? if that means anything... I'm just wondering, is it safe to stop this from trying to startup and what it this file exactly? Could it be from the trojan i removed that was infecting it? therfore i really don't need it? if i do need it where would i get it from? i tried googling it and i got nothing. Thanks.
