Hi all. I posted my problem with my laptop (XP installed) in "Am I Infected" forum first, then i am told to repost it here.
This file, "qkbfiltr.sys" in "C: > Windows > System32 > Drivers" seems to include a keylogger (according to Kaspersky) and everyday my system is refilled with trojans and viruses that steal online game passwords (and freeze the system periodically) no matter how many times i remove them with Kaspersky, MBAM, Spybot and some other removal software.
But i can't remove it, because then my keyboard won't function.
Is it possible to replace it with a healthy system file with the same name and function from another computer? I couldn't try it because no one i know have that file in their drivers folder.
And here is the link to my first post (including some replies from BC staff)http://www.bleepingcomputer.com/forums/t/154819/keylogger-detected-in-system-file-qkbfltrsys/
Much appreciation to anyone who read this and help.
