The Wharps virus was submitted in December, 1992. Its origin or
point of isolation is unknown. Wharps is a non-resident, direct
action infector of .COM programs, including COMMAND.COM.
When a program infected with the Wharps virus is executed, the
Wharps virus will infect one .COM program located in the current
directory. Infected programs will have a file length increase of
572 bytes with the virus being located at the end of the file.
The file's date and time in the DOS disk directory listing will
appear to be unaltered, but actually the seconds field in the file
time will have been set to "62". The following text strings are
encrypted within the Wharps viral code:
"wHaRpS! It is 3:00 a.m. > ETERNAL"
The second text string is displayed by the virus when an infected
program is executed at 3:00 AM. System hangs will also frequently
occur on infected systems.
