Crazy_Boot

Crazy_boot is a stealth boot virus. Upon booting from an infected diskette the virus writes itself into the hard disk’s MBR, installs itself into memory and hooks the interrupt INT 13h. It attacks boot sectors of all diskettes that are not write-protected. Because of an error in the virus code files are damaged when a diskette is being attacked. Occasionally the virus reveals itself by displaying the following text on the screen:

Don't PLAY with the PC ! Otherwise you will get in 'DEEP,DEEP' trouble !... Crazy Boot Ver 1.0.
