How to uninstall FakeMBAM malware

Also Known As: FakeMBAM backdoor trojan
Type: Trojan
Damage level: Medium

What is FakeMBAM?

Backdoor is malware that can be used to steal personal and/or financial data, install additional malware, and hijack devices. Research shows that FakeMBAM is a 'backdoor', which is used by cyber criminals to infect computers with other malware (install additional malware). FakeMBAM is distributed via a fake Malwarebytes installer.

Research shows that the fake Malwarebytes installer uses an identical filename, icon and creates an identical installation directory containing legitimate PE files, as the legitimate Malwarebytes program. In fact, rather than installing the official Malwarebytes software, it creates a fake Malwarebytes installation directory where it hides the FakeMBAM backdoor.

Note that the fake Malwarebytes installer is distributed via automatic updates of Download Studio (free torrent client), NetShield Kit, My AdBlock and Net AdBlock (adblockers) programs. It is very likely that cyber criminals behind FakeMBAM use this backdoor to install malware such as ransomware, data-stealing Trojans, cryptocurrency miners, and other types.

Ransomware is malware that encrypts files so that victims lose access to them without specific decryption software and keys held only by cyber criminals.

Information-stealing Trojans are malicious programs that are used to steal credit card details, login credentials (usernames, email addresses, passwords), identities, and other sensitive information, which could be misused to generate revenue. Cryptocurrency miners are used to mine cryptocurrency by using hardware installed on the victim's computer.

In summary, users who have the FakeMBAM backdoor installed on their computers might become victims of identity theft, suffer monetary loss, lose access to personal accounts and data stored on computers, experience problems relating to browsing safety, online privacy, and other serious issues.

Some examples of other backdoor malware are BazarLoader, BLADABINDI and Upatre.

How did FakeMBAM infiltrate my computer?

As mentioned above, FakeMBAM is distributed via a fake installer for Malwarebytes, which is distributed via automatic updates for one torrent client named Download Studio and three adblockers named NetShield Kit, My AdBlock and Net AdBlock.

The fake Malwarebytes installer does not install the Malwarebytes program, it simply makes it appear that the software is installed by creating an identical installation directory, placing its name in the list of installed programs, etc. The fake installer hides the FakeMBAM backdoor in the new installation directory.

How to avoid installation of malware

Do not trust irrelevant emails that have files attached (or contain website links) and are received from unknown, suspicious addresses. Software should not be downloaded or installed through third party downloaders, installers, unofficial pages or other similar sources/tools.

Use only official websites and direct links. Installed software should never be updated or activated with third party, unofficial tools, since they can install malware. Furthermore, it is illegal to use third party tools to activate licensed software. The only legitimate way to update and activate software is to use tools and functions that are provided by the official developers.

Regularly scan your computer with reputable antivirus or anti-spyware software - keep this software up to date. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.

These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
