Increased scanning speed
A significant boost in scanning speed is one of the key new engine advantages that will be appreciated by users. Dr.Web Virus Finding Engine showed a several-fold increase in speed compared with the previous engine when tested on a 3 terabyte test file collection in Doctor Web's anti-virus lab. A four-fold speed boost was demonstrated on test systems similar to present-day desktop computers. The new virus database format and improved object scanning algorithm allowed the engine to achieve such an impressive result.
Another key advantage of the new engine is its dynamic memory allocation that takes into account the overall system performance and current load. The memory is allocated in real time, so scanning and unpacking large files does not slow down other applications. The new engine has also been optimized for multi-core systems.
ScriptHeuristic and other detection technologies
The structure entropy technology implemented in the new anti-virus engine is truly unique and serves as an alternative to the signature-based search. It significantly improves malware detection.
The optimization of the universal extraction technology FLY-CODE, already used in other Dr.Web products, reduces scanning time by nearly one-third. New heuristic analysis algorithms ensure nearly 100% probability for detection of well disguised Trojan horses. An enhancement in Origins Tracing™ allows it to be used to scan DEX-files (Android).
