CheckSum Family
Description CheckSum Family
These are memory resident harmless parasitic viruses. They trace and hook INT 21h and write themselves to the end of each 8th COM- or EXE-file that is loaded into the system memory ("CheckSum.1232,1233" hit COM-files only). On execution, they calculate the checksum of the virus body and if this sum is not correct they pass the control to DOS. "CheckSum.3022" contains a text in Russian.

It also contains the area of a code which is decrypted and executed only while some file is opened. The name of this file is the key of decryption.
