Technical Details



Vice will not infect files which have a name ending with the following characters:

 ND.  (COMMAND.COM)
   AN.  (SCAN.EXE)
   AV.  (NAV.EXE, MSAV.EXE, CPAV.EXE, TBAV.EXE)
   OT.  (F-PROT.EXE)
   NU.  (Norton Utilities NU.EXE)
			   

In addition, Vice will delete files with the following extensions:

 -V?    (AVP's crc database)
   MS?    (MSAV's crc database)
   CP?    (CPAV's crc database)
			   

Vice can also detect and delete the crc database of Invircible antivirus program, although Invircible will name it's files randomly.

In some cases Vice will also corrupt BAT files, 'infecting' them as if they were executable files. Vice will also occasionally corrupt program files while infecting them; such corrupted files will crash when executed, and there is no easy way to detect them. Otherwise the virus only spreads.

Vice allocates approximately 9 kB of memory and contains this text:

Vice was reported to be in the wild in USA and Finland in April 1996.
