What's new in Dr.Web Anti-virus 4.44.0 Beta :
Doctor Web, Ltd. launches beta-testing of Windows Vista compatible version of Dr.Web for Windows (beta number 4.44.0).
This version incorporated a unique non-signature malware detection algorithm which supplements traditional signature-based scanning and heuristic analyzer of Dr.Web. The malicious codes detected with the help of the new technology are labeled by Dr.Web as «.Origin». The viruses detected by the new technology as «.Origin» are considered to be incurable, which should be taken into account when setting all modules of Dr.Web for Windows.
Practically all components of the product have been modified and improved. The SpIDer Mail module includes now a spml_set.exe file, which provides compatibility with Windows Vista. A number of errors in mail processing in some e-mail clients have been corrected. Some new files have been added to SpIDer Guard. Graphical User interface of SpIDer Guard has been changed to display scanning statistics of the file monitor in a separate window. The module's operation has become more stable. The problems resulting in freezing during the scanning of complex and packed objects have been eliminated, too.
