In addition to creating only one testing
engine for all parts of the AVG Anti Virus System (see AVG
Active Modular Core Page), Grisoft uses the introduction
of AVG 6.0 to continue it's steady advancement of AV heuristics
technology. AVG's Virus Stalker is an essential component
of the Active Modular Core. The Virus Stalker represents more
than six years of continuous development and refinement.
Grisoft was one of the first companies
focused on the serious development of a method called 'heuristic
analysis'. This approach is quite different from any of
the standard methods of virus detection. It no longer depends
solely on scanning files for known viruses listed in the program's
internal database, but instead added another dimension to
let the program work in the same way as would an experienced
virus researcher. The program analyzes the instructions of
tested objects, emulates these instructions and is able to
understand what they mean.
Using heuristic analysis, the program
is able to detect even unknown viruses. Because it is a virus
- it must contain incorrect instructions and methods - which
Heuristic Analysis can detect.
Heuristic analysis first appeared in
1993. Grisoft adopted the heuristic approach as the "core"
of its anti-virus engine and has continued in its development
for the past six years. The result is the best heuristic analysis
engine in the world today - high-end, reliable and quick.
We call it Virus Stalker.
With the extraordinary number of new
viruses being developed on a daily basis, combined with the
ever increasing use of the Internet, the ability to detect
'undiscovered' viruses is more essential than ever before.
