Virus Attack

On 917 night after I restart my PC, Oh my god my PC get attacked by virus.
The person who made the virus should been killed, after a few failed tries to delete, I have to format my HDD.
Lucky in Safe Mode still can safe my details. It seems not a serious virus.

How the virus work:

This virus change my wallpaper and with some porn shortcut icon, making a heavy loading to my PC processor, auto pop up a mini unregistered anti virus to scan, after scanning it pop up a screen for register to delete the virus and have to pay with credit card, F__K!
Reset my PC and it working as same as wanna scan but this time I refuse to do so, you know what it change my mouse cursor to a stupid icon and can't be click. What the .... *_*!!
At last format is the only work I have to do.
SHIT !!! I really hate it !!! FUCK the Virus maker !!!
wallpaper changed click to check with the porn shortcut icon.

Processor loading like hell
A mini anti virus software pop up
After scanning need to register to delete
