Description Cheap.828
It is not a dangerous nonmemory resident encrypted parasitic virus. It searches for COM and EXE files, then writes itself to the end of the file. On 4th, 12th, 17th and 25th of any month it 500 times displays the text:

Then all next "generations" of this virus display these messages on any execution - not depending on the system date (bug in the virus?).
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.
