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)
$
  This version of TbScan is more than 6 months old!
  Statistics show that the amount of different viruses
  doubles about every nine months. For the safety of your
  data it is highly recommended to obtain a more recent
  version of TBAV.

  Consult the file Agents.Doc for information about TBAV
  agents, or consult ESaSS B.V. in The Netherlands:
        Phone: [phone]
        Fax:   [phone]
        BBS:   [phone]

  Press any key to continue...
$

  You specified option 'allfiles'!

  Since there are no viruses that only infect non-executable files, it
  is really sufficient to scan executable files only!

  The only time you should use option 'allfiles' is after you found at
  least one virus in an executable file.

  Be aware that because of the complex nature of TbScan (it performs
  emulation and disassembling of the file being scanned) treating data
  files as executable files causes unpredictable results. False alarms
  may occur.

This unregistered version of TbScan has a few limitations:
- Options 'extract' and 'secure' are not available!
- This version will not execute when put on a network drive. You need to
  install it on your local drive. However you can scan your network drives,
  as long as TbScan itself is put on a local drive.

These limitations will disappear after you have registered TBAV!
Select 'Register' from the TBAV main menu for more information.

  The license or evaluation period of this TBAV software has been
  expired! Extension of a license comes with 50% discount on the
  initial license fee.

  Please contact your TBAV distributor for more information or
  select 'Register' from within the TBAV main menu.

$

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 a code decryption routine or debugger trap.  This is common
   for viruses but also for some copy-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.
$
1  Found instructions which require a 80186 processor or above.
$
@  Encountered instructions which are not likely to be generated by
   an assembler, but by some code generator like a polymorphic virus.
$
X  Stealth capabilities.
$
Y  Bootsector violates IBM bootsector format.
$
t  Program contains a time or date triggered event.
$
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.
