MIX1 is derived from the Icelandic virus, but contains code from the Ping-Pong virus as well. There are two versions known, MIX1 and MIX1-B, practically identical, except for the size. MIX1 displays a bouncing ball on the screen, and garbles all output going to the printer. It will also disable the NumLock key.
One unusual "feature" of MIX1 is that it will only infect files 8192 bytes long or larger.
Depending on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the suspect file, or ask you for a desired action.
