Examples of payloads include randomly moving the cursor slightly, opening up satirical Google searches under Google.co.ck such as "how to remove a virus" and "how to get money" on the user's web browser, and opening various random Microsoft Windows programs (such as the calculator or command prompt). True to the program's name, many parts of the virus are based on Internet memes; for example, the virus overwrites the boot sector with an animation of Nyan Cat.[1][2][3][4][5] Leurak also created a safer version of MEMZ called MEMZ-Clean. The clean version allows the non-destructive payloads to be safely tested and gives the user full control about which payloads are active.[7]
