Description Shake
This is a very dangerous memory resident parasitic virus. It hooks INT 21h. On GetDiskSpace DOS calls (INT 21, ah=36h) the virus searches for .COM files of the current directory, then writes itself to the end of the file. In infected files it sets the time to 60 sec. The virus hooks and does not restore INT 24h. When an infected program is executed, the virus with the probability of 1/16 displays:
Shake well before use

Description Shaker.373
This is a relatively harmless memory resident parasitic infector. It copies itself into the interrupt vector table, and hooks INT 1Ch and 21h. Then it infects COM or EXE files that are executed. Sometimes it 'shakes' the screen.
