    Dear All,

    I am having big trouble with these two virus: Trojan.zeroaccess.C and Trojan.Gen.2.

    I will start from beginning, my system suddenly showed popups that "your system is infected by virus" and suddenly it was an havoc, some software started running some scan automatically and started showing that I have 34 files infected with trojans, and demanded to install their antivirus to prevent. It was a trap and didn't click on purchase but when I tried to stop this application, I failed.

    Meanwhile my Symantec antivirus was showing some popup screens again and again that it has detected these 2 viruses in every 2 minutes.
    Somehow I removed that application from my system as it was preventing to start any other application/window from my system. The worst gift I got on Christmas! :cry

    I have attached logs of the risk and tamper protection from Symantec antivirus. Please help me as this is my business laptop and I am afraid if this will affect my important files.

    Regards
    Ankit

    I know admins must have been busy. Here's more piece of information until they got some more time:

    Virus alert popup is stopped now. I updated my antivirus after that and my antivirus popped another alert for the backdoor trojan at somewhat same location same location:
    C:\$Recycle.Bin\S-1-5-18\$b4666e4c9c567965803d996177a3523f\

    While zeroaccess Trojan was at:
    C:\$Recycle.Bin\S-1-5-18\$b4666e4c9c567965803d996177a3523f\U\

    I am unsure if they are still in my system or not. But they certainly have done some damage:
    1. I am unable to update start my windows update.
    2. I am unable to put on my windows firewall.

    Below is the log attached of backdoor trojan:

    Double-click RogueKiller.exe to run. (Vista/7 right-click and select Run as Administrator)
    When it opens, press the Scan button
    Now click the Files/folders tab and locate these detections:


    • [ZeroAccess][FILE] @ : C:\$recycle.bin\S-1-5-21-2036991376-848325182-1368392876-240998\$b4666e4c9c567965803d996177a3523f\@ [-] --> FOUND
      [ZeroAccess][FOLDER] U : C:\$recycle.bin\S-1-5-21-2036991376-848325182-1368392876-240998\$b4666e4c9c567965803d996177a3523f\U --> FOUND
      [ZeroAccess][FOLDER] L : C:\$recycle.bin\S-1-5-21-2036991376-848325182-1368392876-240998\$b4666e4c9c567965803d996177a3523f\L --> FOUND

    Place a checkmark each of these items, leave the others unchecked.
    Now press the Delete button.
    When it is finished, there will be a log on your desktop called: RKreport[2].txt
    Attach RKreport[2].txt to your next message. (How to attach)

    Now reboot and rescan with RogueKiller and attach that new log as well.

    Tell me how things are running now.

    You are most welcome. Safe surfing. :)

    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend you keep Malwarebytes Anti-Malware for scanning/removal of malware. You can uninstall RogueKiller and HitManPro.
    2. Go back to step 4 of the READ ME and renable your Disk Emulation software with Defogger if you had disabled it.
    3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    4. If running Vista or Win 7, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    5. Go to add/remove programs and uninstall HijackThis.
    6. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders
      related to MGtools and some other items from our cleaning procedures.
    7. After doing the above, you should work thru the below link


    Malware removal from a National Chain = $149
    Malware removal from MajorGeeks = $0
