- FIND1701
- ==============================================================================
-
- This is a single purpose program, than will search out the unique signature
- of a virus that we have named "1701" because it increases the size of the
- infected file 1,701 bytes after it infects it.
-
-
- Usage: FIND1701 [ /switch ... [d:]] ...
-
- where you list the drives you want to find viruses on.
- Switch can be H to heal infected COM files, Q to quarantine
- them, C to only look in current directory.
-
- The default is to heal the file.
-
-
- Examples:
-
- FIND1701 A: Finds and heals all viruses on Drive A:
-
- FIND1701 /Q A: Quarantines viruses on Drive A:
-
- FIND1701 /Q /C Quarantines viruses in current directory.
-
- FIND1701 /Q A: /H B: C: D:
- Quarantines viruses in drive A, heals the
- ones in drive B, C, and D.
-
-
- The program will search the requested drive for all .COM files larger than
- 1701 bytes, and check then check for a unique signature. If it finds the
- correct signature 141$FLu at the correct offset, and if the "Q" switch is
- used it will rename the file to *.VIR and indicate that the file is infected.
- At the end of the program it will tally up all of the infected files, if any,
- and if there are any we suggest you re-boot your computer from a fresh DOS
- Master, re-install the system files, and COMMAND.COM and replace the files
- that have been renamed *.VIR.
-
-
- If you do not supply any switches and just specify the drive, the program
- will find all occurances of the virus, "heal" the infected files, and your
- programs will be left in the same working state before they were infected.
-
-
- The scrolling is continuous, so you might want to re-direct the output to
- a file by: FIND1701 C: /Q > VIRUS.TXT, and then examine the file to see
- which, if any files were infected. The listing has the filename, and the
- directory, so you should be able to locate them pretty easily. Just erase
- all the *.VIR files and replace them with know good copies. Or you can run
- the program again without the /Q switch and "heal" the infected programs.

- This program was written by Thomas Tuerke, SysOp of Gravesend BBS in
- Novato California (415-897-1301). If you use this program to help you
- stamp out this virus you might want to give Thomas a call and let him
- know that it was of value.
