The warning message that appears before running the virus (2.0 version only)

A video of the MrsMajor game is displayed by Windows Media Player. The game is a terrifying maze. It shows a maze room with a green tint, followed by a 'scareface.' The wallpaper is later changed to schemes, as are the icons. When it is fully loaded, a flashing and moving image of a frightening doll named "Mrs. Major" appears on the screen. while Thresh's Theme from League of Legends plays in the background.

It includes rules in Version 2.0 of the virus. One of the rules instructs users not to use Task Manager to remove the virus. If the user tries to open Task Manager, a message with the letter "T" will appear. The rules (v2.0) are as follows:

Your computer has been infected by MrsMajor.
If you dont attend rules, your computer will be "Trash"
Theese are rules:

If the user violates the virus's rules, an RSoD (Red Screen of Death) screen will appear informing the user that they have violated the virus's rules. The error code is "TROJANS NEVER JOKE RESPECT THE TROJANS," which may indicate that the malware is a Trojan. If the user turns off their computer while the virus is still active, the virus will destroy the operating system by deleting some boot files. The RSoD screen (v2.0) reads as follows:

A problem has been detected and windows has been shutdown to prevent damage to your computer.
