Quell.511
It is not a dangerous memory resident parasitic virus. It hooks INT 1Ch (system timer), 21h and writes itself to the end of COM files that are executed. The virus INT 1Ch handler each time reads data from CMOS memory - current day and month number, compares them with May 15 and does nothing. It seems that at this day the virus has to run some payload subroutine, but it absents in this virus code.
The virus contains the string:
COMcom |
