Cant get rid of rootkit

  1. Hey, I have attached logs and i have appeared to clean most of the crap up such as protection center and other malware but i cannot get rid of a rootkit that keeps being detected by Gmer and avast but cannot be removed even in safemode. I believe i have a variant of the TDSS rootkit but i cannot delete it in the registry because it hides itself

    thanks for your help

    With over 1,000 post, I assume you aware of a risk of running Combofix on your own?


    Please download PragmaFix and double click on it to run it.
    A log will open, when scan is done.
    Post the log.

    Note - when you run PragmaFix you need an active internet connection!

    Go to Start -> Run, copy and paste the following command in the run Box and Click OK (Vista or Windows 7, click on the Vista or Windows 7 Orb, copy and paste the following command in the "Start Search" box and press Enter).

    PragmaFix -auto

    It will produce PragmaFix.log in the C:\ folder.
    Please post the results here.

    Very good :)
    It's gone.

    Please, delete your GMER file, download fresh one and post its log.
    Delete your Combofix file, download fresh one and post its log.

    The online scan did pick up a few things but i believe that they were on the cd that i had in the drive (it was the ultimate boot cd 4 windows) so i think they are false positives

    If D is your CD drive, I'd suggest destroying that CD.


    Your computer is clean [​IMG]

    1. We need to reset system restore to prevent your computer from being accidentally reinfected by using some old restore point(s). We'll create fresh, clean restore point.

    Turn off System Restore:

    - Windows XP:
    1. Click Start.
    2. Right-click the My Computer icon, and then click Properties.
    3. Click the System Restore tab.
    4. Check "Turn off System Restore".
    5. Click Apply.
    6. When turning off System Restore, the existing restore points will be deleted. Click Yes to do this.
    7. Click OK.
    - Windows Vista and 7:
    1. Click Start.
    2. Right-click the Computer icon, and then click Properties.
    3. Click on System Protection under the Tasks column on the left side
    4. Click on Continue on the "User Account Control" window that pops up
    5. Under the System Protection tab, find Available Disks
    6. Uncheck the box for any drive you wish to disable system restore on (in most cases, drive "C:")
    7. When turning off System Restore, the existing restore points will be deleted. Click "Turn System Restore Off" on the popup window to do this.
    8. Click OK

    2. Restart computer.

    3. Turn System Restore on.

    4. Make sure, Windows Updates are current.

    5. If any Trojan was listed among your infection(s), make sure, you change all of your on-line important passwords (bank account(s), secured web sites, etc.) immediately!

    6. Download, and install WOT (Web OF Trust): http://www.mywot.com/. It'll warn you (in most cases) about dangerous web sites.

    7. Run defrag at your convenience.

    8. Read How did I get infected?, With steps so it does not happen again!: http://www.bleepingcomputer.com/forums/topic2520.html

    9. Please, let me know, how is your computer doing.
