This virus is a bit unusual, to say the least. It contains the following message:
This program is infected by a HARMLESS Text-Virus V2.1 Send a FUNNY postcard to : Sylvia Verkade, Duinzoom 36b, 3235 CD Rockanje The Netherlands. You might get an ANTIVIRUS program.....
It will display this message when an infected program is executed, but if the above text is tampered with, the following message, (which is stored in an encrypted form) will appear instead:
FUCK YOU LAMER !!!! system halted...$
Some people have a weird sense of humor...
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
Detailed instructions for F-Secure security products are available in the documentation found in the Downloads section of our Home - Global site.

Two versions are known, only slightly different - possibly modified to avoid some anti-virus program. When an infected program is run, the virus will seek out up to 5 .COM files to infect. It will search drive C: and the current drive. The three system files, COMMAND.COM, IBMBIO.COM and IBMDOS.COM are not infected. The virus adds 1301 bytes to the beginning of the files it infects (and also 31 bytes to the end), but does no other damage. The girl mentioned above exists, but she says that she has no idea who the author is, although there is a rumor he is her ex-boyfriend.
