  The Thunderbyte Anti-Virus utilities  provide a collection of  sophisticated
  programs which offer various ways to check for, identify and remove known as
  well as unknown viruses from hard and floppy disks on PCs or across networks.

  TBAV is upgraded every two months.  Free hotline support is provided for all
  registered users via telephone, fax and electronic bulletin board.  Read the
  comprehensive documentation files for detailed info.   BBS: [phone]

WARNING!
$

 WARNING! memory
$

  Since an active virus in memory  may interfere with the
  virus  scanning  process, it is  highly  recommended to
  immediately power down the system, and to reboot from a
  write-protected clean system diskette!

  Note: if you used any virus scanner just before you invoked
  TbScan, it's possible  that TbScan detected  a signature of
  the other scanner in  memory,  rather than an actual virus.
  In that case you should ignore this warning.
  Do you want to Q)uit or to C)ontinue? (Q/C)

$

Heuristic flags:
$
c  No checksum / recovery information (Anti-Vir.Dat) available.
$
C  The checksum data does not match!  File has been changed!
$
F  Suspicious file access.  Might be able to infect a file.
$
R  Relocator.  Program code will be relocated in a suspicious way.
$
A  Suspicious Memory Allocation.  The program uses a non-standard
   way to search for, and/or allocate memory.
$
N  Wrong name extension. Extension conflicts with program structure.
$
S  Contains a routine to search for executable (.COM or .EXE) files.
$
#  Found an instruction decryption routine.  This is common
   for viruses but also for some protected software.
$
V  This suspicious file has been validated to avoid heuristic alarms.
$
E  Flexible Entry-point.  The code seems to be designed to be linked
   on any location within an executable file.  Common for viruses.
$
L  The program traps the loading of software.  Might be a
   virus that intercepts program load to infect the software.
$
D  Disk write access.  The program writes to disk without using DOS.
$
M  Memory resident code.  The program might stay resident in memory.
$
!  Invalid opcode (non-8088 instructions) or out-of-range branch.
$
T  Incorrect timestamp.  Some viruses use this to mark infected files.
$
J  Suspicious jump construct.  Entry point via chained or indirect
   jumps.  This is unusual for normal software but common for viruses.
$
?  Inconsistent exe-header.  Might be a virus but can also be a bug.
$
G  Garbage instructions.  Contains code that seems to have no purpose
   other than encryption or avoiding recognition by virus scanners.
$
U  Undocumented interrupt/DOS call.  The program might be just tricky
   but can also be a virus using a non-standard way to detect itself.
$
Z  EXE/COM determination.  The program tries to check whether a file
   is a COM or EXE file.  Viruses need to do this to infect a program.
$
O  Found code that can be used to overwrite/move a program in memory.
$
B  Back to entry point.  Contains code to re-start the program after
   modifications at the entry-point are made.  Very usual for viruses.
$
K  Unusual stack.  The program has a suspicious stack or an odd stack.
$
Y  Bootsector violates IBM bootsector format.  Missing 55AA-marker.
$
p  Packed program.  A virus could be hidden inside the program.
$
i  Additional data found at end of file.  Probably internal overlay.
$
h  The program has the hidden or system attribute set.
$
w  The program contains a MS-Windows or OS/2 exe-header.
