ActiveX controls are the modern
rendition of OLE, or .OCX files. A simplistic example of OLE
(Object Linking and Embedding) allows a user to embed the
calculator into a word processor. ActiveX controls rely on the
Windows operating system, requiring developers to create version
specific controls. Unlike Sun's Java, ActiveX is able to
interact with the operating system. This has led to security
vulnerabilities in some instances, with the KAK worm perhaps
being the most notorious.
Behavior blocking monitors file activities,
preventing certain modifications to the operating system or
related files. For example, behavior blockers may monitor
the registry, and warn users accordingly if a file being
executed is attempting to modify the system registry. Some
files, of course, do this legimately, i.e. a SETUP program.
Others, however, have malicious intent and try to modify the
registry to launch on every startup or when a particular
access is made. While some find behavior blocking intrusive,
it can be a valuable addition to defending systems against
the threat of viruses and other forms of
