Dr.Web Announced New Virus-Funding Engine
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 tera-byte test file collection in Doctor Web's anti-virus lab. A four-time 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.
The new engine supports dynamic memory use, so the amount of memory allocated to the anti-virus changes depending on the system performance and concurrent user and system tasks. Memory allocation is performed in real time, so the system performance doesn't decrease while the anti-virus extracts large files. Anti-virus operation in multi-core systems has been optimized similarly.
"The new system resource manager estimates current system load before utilizing resources for scanning. The Scanning Engine service controls engine memory operations and decides whether the engine should be given all the memory available or make sure users can perform their tasks undisturbed The new engine can also determine a reasonable scanning depth for a particular object, so valuable system resources won't be wasted", Konstantin Yudin, Doctor Web Windows anti-virus project manager said.
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 unique universal unpacking technology FLY-CODE has been used in Dr.Web products before but with an upgrade providing a 30% scanning time decrease and new heuristic analysis algorithms it achieves almost one hundred percent probability for detection of well protected Trojan horses. An enhancement in Origins Tracing™ allows to use this technology for scanning DEX-files (Android).
The update is available for Dr.Web anti-virus, Dr.Web Security Space, Dr.Web Desktop Security Suite and Dr.Web Server Security Suite series 6 and 7. The update will be downloaded and installed automatically. To use the updated Dr.Web CureIt, you can download it from Doctor Web's site. Dr.Web CureNet! users only need to start the updating module.
