Picket Family
Description Picket Family
These are very dangerous memory resident encrypted parasitic viruses. They hooks INT 21h ("Picket.1034" hooks INT 1Ch also) and write themselves to the end or to the middle of COM files.
While inserting into the middle of the file they search for the data area that contains the constant byte, then store that byte and overwrite that area with the virus copy. That routine contains several errors, and the file size can grow more than 64K while infecting, and the file stays corrupted.
These viruses contain text strings in Russian.
