(c) 1992-93 by the same author. VSIGN.1.0 is released to the public due to the following reasons: (1) Many users added the anti-virus Commands in their Autoexec.bat so when the machine is booted, it automatically scans the entire hard disk for signs of Viruses. However, I found it is very time consuming. I personally don't have much patience, so I use the VSIGN just for quick information if my Command.com has changed in size or not. (2) Almost all known viruses including the most popular viruses: STONED, FLIP, MICHELANGELO... can change the size of the Command.com. VSIGN will do just that: Warn the user of changes in Command.com. If the Command.com has been changed in size, it is one of the early signs to warn the user that there's a possible Virus residing on the hard disk. So further "scan" and "clean" by using the anti-viruses program maybe carried out. (3) Most anti-virus programs need to be updated constantly to add new viruses signature-definitions. With more than 50+ new viruses each month, no one can catch up and win the race completely. Fortunately, all anti- viral products are doing their best to catch up and to beat the viruses whenever a new virus has been found. What about the end user ? Most PC users either don't have any anti-virus scan program or, have not updated their viruses-definition file for a long time... What is the immediate solution then ? The answar is: Check the size of the Command.com ! VSIGN can do just that ! (4) Although VSIGN cannot scan or clean your infected files, it is useful to warn you that the Command.com maybe changed due to possible viruses on the hard disk. And it only takes a few seconds to find out at boot-up. ------------------------------------------------------------------------------- INSTRUCTIONS ------------ To install and to use the VSIGN.EXE is very simple.
