Created in Europe to combat the growing threat of intelligent
and sophisticated viruses around the world, ThunderBYTE Anti-Virus
Utilities have been leaders in the anti-virus computer software
field for several years, boasting the world's fastest scanner.
Using a combination of traditional and proprietary heuristic
"seek-and-destroy" techniques to ferret out even the stealthiest
viruses, trojans, and logic bombs, these utilities offer an
enhanced level of anti-virus protection at speeds that are
unsurpassed in the PC arena.

ThunderNEWS * A BREAKTHROUGH IN DETECTION OF ENCRYPTED POLYMORPHIC VIRUSES *
────────────────────────────────────────────────────────────────────────────
ThunderBYTE has once again defined the cutting edge in virus
detection technology with the first and only generic decryption
virus scanner, that can detect encrypted polymorphic viruses.
TbScan, ThunderBYTE's flagship virus scanning product, now
incorporates a code emulator that automatically decrypts any
encrypted virus without requiring any information about the
specific virus.
A polymorphic virus is one which uses advanced encryption techniques to
assemble varied (yet entirely operational) clones of itself. This technique
renders signature-based anti-virus scanning technology obsolete.
ThunderBYTE has overcome the obstacles presented by these advanced
polymorphic and encryption engines by using a real code emulator in TbScan.
"The emulation done by TbScan is purely software based," says Howard H. Thaw,
President of ThunderBYTE North American Sales. "No instruction of the file
to be examined will ever be executed. This is so we can be 100% sure that
something undesirable will not be activated."
"No longer do we have to create algorithmic virus detection routines to
detect complex polymorphic viruses," says Robin Bijland, President of ESaSS
B.V., Nijmegen, The Netherlands, the company that developed TbScan. "All
polymorphic viruses can now be detected by simple signature. We are now able
to distinguish between different viruses that have been encrypted by the same
engine. For example, instead of naming every MtE (Mutating Virus Engine)-
based virus 'MtE', we can now name them 'MtE:Pogue', 'MtE:Fear', etc."
Encrypted polymorphic viruses are the latest and most difficult to detect
class of viruses, since each file infected by the virus looks completely
different. Serious virus researchers from around-the-world exchange virus
samples with each other to confirm rapidly the authenticity, classification
and reliable detection of new viruses.
Recently scientists at ESaSS examined samples of a software infection
emanating from The Black Baron's Simulated Metamorphic Encryption Generator
(SMEG) that clearly indicates a new level of sophistication with viruses.
"After failing to detect the new virus with simple signature-based scanners,
generic techniques, and even our own proprietary heuristic methods,"
commented Dr. Frans Veldman, Author of ThunderBYTE Anti-Virus and Chief
Executive of ESaSS, B.V., "the ESaSS scientific team completed work on a
sophisticated "generic decryption scanning engine", which detected the
mystery virus within seconds."

A new version of the ThunderBYTE Anti-Virus Utilities (TBAV) incorporating
this generic decryption and code emulation technology is now available from
ThunderBYTE North American Sales, which is a partnership between the
developers, ESaSS B.V. (The Netherlands) and TCT (Thaw Computer Technology
Inc.), a respected and established computer security organization with
offices in the United States and Canada. Site license inquiries and
evaluation software are available by calling 1-800-667-TBAV or dialing into
ThunderBYTE Online Information System at 613-930-9999 (2400-19200 baud
supported).
