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: +31- 59- 182 011

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.

Error: Some internal limit exceeded!
No executable files found!
Error: Can not create logfile!
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 evaluation period of this unregistered version of TBAV has been
expired! You should now either register your copy or remove it from
your system.

If you register, you may continue to use TBAV, and as an extra bonus,
some additional features will become available to you!

Select 'Register' from the TBAV main menu for more information.

Process aborted by user!
No drives to be scanned found!

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.
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.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read:
