The Psychogenius, or Cover Girl, virus was received in December, 1991
from a United States source. Psychogenius is a non-resident direct
action overwriting virus which infects any executable or non-
executable file. It permanently corrupts any files it infects.
When a program infected with Psychogenius is executed, it will infect
all files which exist in the current directory. It does not care if
the files are executable, or if they are data files of some sort.
Infected files will have had the first 723 bytes overwritten by the
viral code, and their date and time updated to the system date and
time when infection occurred. There will be no change in file
length if the file's original length was 723 bytes or larger. Files
which were originally smaller than 723 bytes will now be 723 bytes
The following text strings can be found in the viral code in all
"Oh, oh, oh, She's my cover girl,
Oh, oh, oh,
oh, oh, oh,
Cover Girl by The New Kids On The Block
Hangin' Tough (c) 1988 CBS Records"
It is not possible to disinfect infected files as the first 723
bytes have been overwritten. Files should be deleted and restored
from a clean backup copy.
Known variant(s) of Psychogenius are:
Psychogenius-B: Functionally equivalent to the original virus,
this variant has one byte which differs from the original.
