PingPong.a
Description PingPong.a
This virus is similar to "Ping-Pong". The difference is that instead of a jumping ball, it causes the setting of the 13h interrupt vector to a subroutine, which destroys the first eight sectors of a floppy disk.
Ping-Pong modified by Yankee
This is the result of a modification of the "Ping-Pong" virus by the "Yankee" virus. Every time this infector is loaded, one unit is added to the version number (special byte). When zero (255+1) is reached, the virus deactivates.
