- Having recently had an outbreak of the Form virus a method of removing the
- virus from a significant number of floppy disks was required. Preferably a
- method which could be distributed freely was needed.
-
- While there is a number of good shareware packages around, registration
- (or lack thereof) could cause problem.
-
- Hence a small C program was written to remove the offending virus and this
- is totally free. While no warranty is supplied it does seem to work.
-
- The program works only on floppy disks, hard disks can be cleared up with
- the DOS command SYS. To use the program boot from a write protected CLEAN
- system disk. Then run the deform program specifying the required drive.
- For example:
- DEFORM A:
-
- The program works by first checking the floppy disk is infected. If it is
- then the original boot sector is copied back into sector zero and the two
- bad sectors are cleared in the file allocation table.
-
- The program is supplied in both source and compiled form. It may be freely
- copied and distributed with the only restriction that no fee is charged.
