The MEMZ trojan would spam the user with dangerous website searches, flashing colors, error messages and sounds, and then eventually, would crash the PC. Attempting to stop the virus would blue screen the PC.
Rebooting the PC after the trojan's attack would show up with the message "Your computer has been trashed by the MEMZ Trojan. Now enjoy the Nyan Cat."
A midi file of the nyan cat plays through the PC tones and a DOS render of the nyan cat will appear, animated.
It has a different coloration compared to the original nyan cat, having a different shade of pink, blue, etc.
Rebooting again will always bring the user to the message and nyan cat, so the PC becomes unusable.
Joel from Vinesauce destroyed a Windows 10 using the same virus, and then began to corrupt the MEMZ Nyan Cat bootloader, resulting in some funny and nightmarish images.
The safer 4.0 version of MEMZ has the dangerous parts taken out, so the PC is still usable, which meant that the nyan cat was removed and no longer exists in later versions of the troll trojan.
- The midi file used on the nyan cat screen is the same song used for the Retro Nyan Cat, but uses the keyboard beeping tones instead.
