    windows 8.1 rootkit problem


    hi ! im quite new to these forums, but i think some of you might help me.

    i was dealing with some torrents of different games, and i got rootkit infection from those. i scared quite a bit, and o readed from somewhere that if i reinstall windows COMPLETELY it will get deleted. well, i did that. after i updated windows and all that stuff, i noticed that my disk usage is all the time around 98-100%, and i didnt even use the pc. i ran antivirus scan with free version of avast. it said that i got 3 infections. they were all rootkits, and i clicked on 'delete'. it didnt do anything, just stayed there. i changed the option to 'move to karantine' - same thing, didnt do anything. well i kept spamming both of them, and then avast asked me to restart my pc and ran a scan when windows starts. i didnt do that. then i ran a scan with antibytes malware, and it said that i didnt have any infections. i reinstalled windows once again, and ran antivirus several times. nothing. i also ran some rootkit finders like rootkitrevealer, roguekiller,tdsskiller and spohos virus removal tool, and they found nothing. i also tried with antibyte malware's own rootkit finder, and it didnt find anything. now my disk usage is normal, but im still quite scared that if i have the rootkits. so do you guys have any ideas, any really powerful rootkit finders, any suggestions anything, what i could do? or did i got rid of the viruses ? im quite new to viruses and such since i havent had much to deal with them, but this one really shocked me.

    Torrenting games and got hit with Rootkits - oh dear what a shame........

    Anyways, you might need to do a complete reinstall of windows using your install disc

    well, im running windows 8.1, and i did full reinstall of windows. in english its something called' delete everything and reinstall windows' from the left bar, and i opened that. there was some options and i took the one where it cleans everything, including all drives and everything. its basicly same as when u get a new pc, that state. and i dont have any windows discs, they didnt give me one with the pc. so any other ideas ?

    With the action you took with your recovery partition you should be OK unless the recovery partition got infected also. I suggest that you order the Recovery Disks from your computer manufacturer in the event it happens again. You would format the drive entirely before using your recovery disks.

    Yes your disk usage will be high in the beginning after restoring your system. Windows is doing housekeeping and maintenance but should return to normal after 1 or 2 days.

    For information, only formatting/reinstalling Windows isn't enough for the nastiest rootkits that can affect your MBR. Repartitioning might help but not always. The safest solution is to wipe or fix the MBR. And this done from an external drive (or CD/DVD) from which you boot (to be sure it hasn't been affected by the rootkit too).

    Here is a tutorial to fix the MBR : MBR - Restore Windows 7 Master Boot Record - Windows 7 Help Forums

    Also don't count on refresh/restore to get rid of this kind malware. When talking about reinstall, it's assumed to be from a clean install disc, something read-only to be safer.

    If your usb key was made after you got infected, you might be out of luck.

    Sure. If the Recovery console is included on your USB stick, follow the tutorial I linked, format your OS drive, then reinstall.
