MEMZ is a Trojan that has received much attention from Windows PC users lately, who are intrigued by the vortex images it creates on their computers.

To this day, MEMZ still remains an obscure virus for many Windows users, and the chance of getting more information from Microsoft is zero now.

The tech giant has locked the original thread about this Windows 10 MEMZ virus. There is only this active thread Microsoft Community. It seems like it all began as a joke, but many users got affected by it.

Leurak, the creator of the virus, intended it only to be for fun, and it was for Youtuber danooct1’s ‘Viewer-made malware’ series. He privately sent it out to some others, and some of the reciepients failed to follow Leurak’s request NOT to share it to their peers or strangers.

MEMZ virus on a stream was originally created by Leurak for YouTuber danooct1’s Viewer-Made Malware series.

Now it’s available to the public and you can find several versions on GitHub: some are MEMZ virus Clean and others Destructive.


What is and how do I remove the MEMZ virus?

1. What is the MEMZ virus?

MEMZ is a custom-made Trojan that uses highly complex and unique payloads which activate in a row. The first few payloads are harmless, but the final payload can make your PC completely unusable.

Once a computer is infected, the virus displays a message informing users they won’t be able to use their machines if they restart them. So remember to never restart a PC with MEMZ on it.

If you’re wondering about the way this Trojan manifests itself, some of the effects include automatic web search queries in the browser, the mouse cursor changing form, and random clicking.

Many other weird errors and glitches concluding with a screen tunnel from countless screenshots can also take over your display. 

Furthermore, MEMZ Trojan can do an interesting and also very destructive thing: overwrite the first 64 KB of the hard disk. 

Your machine won’t be able to run the OS and will display this message instead: Your computer has been trashed by the MEMZ Trojan. Now enjoy the Nyan cat…

After that, the Nyan Cat will take over your computer. MEMZ’s trademark is the Nyan Cat animation acting as a bootloader.

There are two versions of MEMZ: a harmless one, which people use for fun, and a malware version that affects the Master Boot Record. The second one is dangerous and can make a PC unusable.


2. Remove MEMZ from Command Prompt

  1. Open the search bar and type cmd.
  2. Select Command Prompt as admin.
  3. In the Command Prompt window, type the following command and press Enter: taskkill /f /im MEMZ.exe 

This kills all the MEMZ processes without crashing the system. The downside is that the Nyan Cat will still appear after your restart your computer.
