Windows XP Horror Edition
June 05, 2019
 |
| Windows XP Horror Edition Windows XP Horror Edition is a screamer application created by Wobbychip.
This application icon looks like the Windows XP icon in Red color. When you run the application, it shows you the Windows XP update screen. Obviously, it is a fake update screen. After a 66% update, an error message pops up and says "Setup cannot copy the file ntdll.dll Setup will use the file 666.sys". At this moment your computer completely infected by this malware and there is no escape. Anyway, after clicking the OK button you can see a red log in screen with an eye picture and Windows XP sweet login sound turns into a creepy sound.
After login, you can see your Desktop completely changed. Background wallpaper turns into skulls, Start button replace with the DEAD button and you find the other two objects on your Desktop. 1. Don't open me.txt 2. Nothing (PNG image file) and you can see creepy images continuously appear in an interval of few seconds with creepy sound effect. If you click on Don't open me the text file it will show you " CONGRATULATIONS YOU OPENED ME DO YOU WANNA PLAY A GAME OKEY THEN LOOK BEHIND YOU" and it will show a Game Over message. If you click on the Start button which now turns into a DEAD button, the screen goes blackout and appears a door. When you click on the door it will open and there became a jumpscare after that bloodletter says you "GO TO SLEEP" then return to Desktop. If you open the Nothing PNG file, you can see a creepy short video of a little girl and a monster granny through the animation. At last, if you click on the Desktop Computer icon it will show a message "DO YOU SERIOUSLY WANT TRASH YOUR COMPUTER FOREVER?" No matter what you choose Yes or No it will send your Computer to Recycle bin. When your computer trashed a red screen of death (BSOD) appear on your screen. When you try to restart your computer it will show a message "I'M WATCHING YOU" and unfortunately your computer never boot again because the MBR was overwritten. Screenshots:
