Having trouble removing a backdoor.bot. Malwarebytes and Microsoft both say they've found it, and removed it, but the browser redirect continues. I also am unable to remove the rogue svchost in c:\windows\system. Thanks in advance for your help! Here are the logs:

Hello, and welcome to Malwarebytes, ajronline:

Sorry to hear that your computer may be infected.

We cannot review scan logs or work on malware detection/removal in this part of the General MBAM forum.

So, please read the following to get started on the cleaning process.

FIRST, your log indicates you are running an old version of MBAM with an ancient version of the malware definitions.

So, the first thing you might want to try is updating to the current version.

Here is how to do that:

  • If you are using MBAM PRO, be sure to have your license ID and key handy first.
  • Download and run mbam-clean.exe from here.
  • It will ask to restart your computer, please allow it to do so (very important!).
  • After the computer restarts, temporarily disable your Anti-Virus and install the latest version of Malwarebytes' Anti-Malware from here.
    Note: You will need to reactivate the program using the license ID & key you were sent via email, if you are using the PRO version.
  • Launch MBAM and set the Protection and Registration (if using the PRO version).
  • Then go to the UPDATE tab (if not done during installation) and check for updates.
  • Restart the computer again and verify that MBAM is in the task tray (if using the PRO version).
  • Now set up any file exclusions as may be required in your Anti-Virus/Internet-Security/Firewall applications. Then restart your Anti-Virus/Internet-Security applications. You may use the guides posted in the FAQs here, or ask and we'll explain how to do it.

SECOND...

IMPORTANT NOTE: Please do NOT use any temporary file cleaners unless requested - this can cause data loss and make recovery difficult

FOR EXPERT ASSISTANCE with cleaning your system, there are 3 support options:

  • Option 1 -- Free, Expert advice in the Malware Removal Forum
  • Option 2 -- Free support for paying customers using MBAM PRO -- Contact MBAM Support via email
  • Option 3 -- Premium, Fee-Based Support

OPTION 1

As we don't deal with malware removal in this area of the forums, you'll need to start a topic in the Malware Removal forum so that a qualified helper can help you fix any malware-related problems/infections.

  • First, please print out, read and CAREFULLY FOLLOW the directions here, skipping any steps you are unable to complete.
  • If the infection has so crippled the computer that you cannot follow most/all of the requested steps, then please just proceed as advised below:
  • Then please post a NEW topic in the Malware Removal forum.
  • Please do NOT post in an open topic started by another member in the malware removal forum, even if the problem appears to be similar to yours.
  • When posting your new thread, under "options", make sure to select Track this topic and choose Immediate Email Notification, so that you're alerted when someone has replied to your post.
  • One of the expert helpers there will give you free, one-on-one assistance when one becomes available.

IMPORTANT NOTE: Please do NOT make any further changes to your computer such as (Install/Uninstall programs; use special fix tools; delete files; edit the registry; OR use temp file cleaners, etc...) unless advised by a malware removal helper. Doing so can result in system changes which may hinder the attempts by a helper to clean your machine.

IMPORTANT NOTE: Please DO NOT post back to your topic or "bump" it within the first 48 hours.

Replying to your own posts changes the post count from zero. Helpers are looking for topics with zero replies. If you reply to your own post, helpers may think that you're already being helped and thus may overlook your post. This will only delay your obtaining assistance.


  • o If there is no reply from any experts after 48 hours, you may reply to the topic, asking for help again.
    Or
    o You may send a Private Message to a Moderator, asking for assistance.

OPTION 2

Alternatively, as a paying customer using MBAM PRO, you can contact the help desk at support@malwarebytes.org or here.

OPTION 3

If you would like to use the Malwarebytes Premium Services (Comprehensive solutions to all your computer support needs -- from installation and set-up to troubleshooting and tune-ups), please go to the Malwarebytes Premium Services support site.

Please be patient -- someone will assist you as soon as it is possible.

Thanks very much!

PS: Please use the zMn2t.jpg button instead of other ones when you reply here and at the other forums, so that it will be easier to read. :)
