1) INTRODUCTION :

BUGFIX is a background disinfection and system security
program against the EXEBUG 1 and EXEBUG 2 virus.


2) WHAT IS THE EXEBUG VIRUS ?

Besides the STONED virus, the EXEBUG virus is the most
common virus in South Africa. However unlike the STONED
virus, the EXEBUG virus causes malicious damage and makes
use of an advanced stealth technique called tunneling to
hide itself from anti virus programs.

On floppy disks, the EXEBUG virus infects the BOOT SECTOR
and on hard drives it infects the PARTITION TABLE.

A noticeable effect of the EXEBUG virus is that it
interferes with the CMOS setup and removes diskette drive 0
from the setup. Booting from a clean DOS disk will result
in the hard drive not being accessible as the virus will
over-write the partition table.

There are two versions of the EXEBUG virus :

EXEBUG 1 modifies .EXE files into droppers (files that when
executed DROP the virus into the boot sector / partition
table) and modifies .EXE files to become Trojans,which when
executed, will over-write the FAT, root directory and other
vital areas of the hard drive with garbage.

EXEBUG 2 is different from EXEBUG 1 in that it has the
damage routine called from the boot sector instead of the
Trojans. THE EXEBUG 2 VIRUS ACTIVATES IN MARCH, AND OVER-
WRITES THE HARD DRIVE WITH GARBAGE.

6) OVERVIEW :

BUGFIX is a memory resident program anti virus program that
detects and removes the EXEBUG version 1 and 2 virus. The
software makes use of a two-layered protection mechanism.
The first layer performs the detection and disinfection
procedure, and the second ensures that your system remains
free of the EXEBUG virus.

a) On execution of BUGFIX.COM, the program will inspect the
boot sector of all volumes on your disk drive(s). If it
detects the EXEBUG virus in memory, it will ask you to
boot the computer from a clean DOS disk and run BUGFIX
again. BUGFIX will then disinfect the hard drives.

NOTE: As the EXEBUG virus interferes with the diskette 0
entry in the CMOS setup,you will have to set up the CMOS
diskette configuration manually.

b) Now that you have removed the EXEBUG virus, you must
ensure that you do not get infected again. To do this,
include BUGFIX in your AUTOEXEC.BAT file, so that it
is run every time you boot the computer. Any disk that
is inserted into the diskette drives is automatically
checked in the background. If the EXEBUG virus is
detected, BUGFIX will automatically remove it.
