  1. Win32:vbstat-c(trj) - deleating files from HJT scan

    Hello!

    I have an avast! antivirus programe and it has detected the troyan Win32:vbstat-c(trj). My computer went slow and each time I have opened an Internet Explorer window a lot of pupups came out.
    On this pages I've found the steps to follow to clean my computer on http://www.techspot.com/vb/topic58138.html. I have just finished with HJT scan from the Step 13 and now I don't know what to delete and what not. I post here the HJT rapport aswell as Combofix and AVG Antyspyware. AVG Antirootkit dodn't find me anything.
    Could anybody please help me with deleteng the possibly infected files?
    For now there are no more pupups and avast! also doesn't give me the troyan alert.
    thank you very much for your help so far!

    1. Please download The Avenger by Swandog46 from HERE. Save it to your Desktop and extract it.

    2. Download the attached avengerscript.txt and save it to your desktop

    Note: the above code was created specifically for this user. If you are not this user, do NOT follow these directions as they could damage the workings of your system.

    3. Now, start The Avenger program by double clicking on its icon on your desktop.

    Under "Script file to execute" choose "Load script from file".
    Now click on the folder icon which will open a new window titled "open Script File"
    navigate to the file you have just downloaded, click on it and press open
    Now click on the Green Light to begin execution of the script
    Answer "Yes" twice when prompted.

    4. The Avenger will automatically do the following:

    It will Restart your computer. ( In cases where the code to execute contains "Drivers to Unload", The Avenger will actually restart your system twice.)
    On reboot, it will briefly open a black command window on your desktop, this is normal.
    After the restart, it creates a log file that should open with the results of Avenger’s actions. This log file will be located at C:\avenger.txt
    The Avenger will also have backed up all the files, etc., that you asked it to delete, and will have zipped them and moved the zip archives to C:\avenger\backup.zip.

    5. Please attach the content of c:\avenger.txt into your reply, as well as a fresh HJT log.

    Regards Howard :)

    done the Avenger

    Hello!
    Thank you very much for such a quick answer!
    I have done what you've written to me and here I'm sending the avenger.txt and HJT log files.
    After Avenger restarted the computer, a grey window appeared on my Desktop saying:
    Error loading C\WINDOWS\System32\uuqwjdah.dll
    The specified module could not be found.

    Went something wrong?
    Thanx again for your help!

    Run HJT with no other programmes open. Click the scan button. Have HJT fix the following, by placing a tick in the little box next to(if there).

    O2 - BHO: (no name) - {B962A9D7-4E7E-412F-8EDE-D097B1519A8c} - C:\WINDOWS\system32\xwvbbatl.dll (file missing)

    O4 - HKLM\..\Run: [WindowsService] rundll32.exe "C:\WINDOWS\system32\uuqwjdah.dll",realset

    Click on the fix checked button.

    Close HJT.

    Locate and delete the following bold files and/or directories(if there).

    C:\WINDOWS\system32\uuqwjdah.dll",realset

    Reboot your system and post a fresh HJT log. let me know if you`re still having problems.

    Regards Howard :)

    Hello, wow, that was really quick, thank you so much! I've done what you've said and here I'm posting the HJT log 3. I have no error notifications anymore and also no virus or troyan alert. Is my computer clean now?

    Is avast! a good anti-virus program or shall I install something better like Norton?

    Thanks again!

    Your HJT log is now clean.

    Turn off system restore.(XP/ME only) See how HERE.

    Now, turn system restore back on. This will have deleted all your old restore points and any nasties that are in them. It will also have created a new, clean restore point.

    Avast is a very good antivirus programme and is certainly a lot better than Norton. No antivirus programme can stop every kind of malware.

    It appears you`re not running any firewall software. I suggest you install one of the following firewall programmes.

    Zonealarm or Kerio free firewall programmes.

    If you have any further virus/spyware problems, please post in this thread.
