Avira periodically "cleans out" its virus definition files, replacing specific signatures with generic ones for a general increase in performance and scanning speed. A 15 MB database clean-out was made on 27 October 2008, causing problems to the users of the Free edition because of its large size and Avira‘s slow Free edition servers. Avira responded by reducing the size of the individual update files, delivering less data in each update.

Bitdefender introduced Active Virus Control in August 2009.
This technology continuously monitors each program (specific processes) running on the PC as it executes, and it notes any malware-like actions. Each action is scored and, when a given threshold is reached, the process is reported as harmful. Unlike heuristic technologies that check executable files when they are accessed or started, Active Virus Control monitors everything applications do as long as they are active.
In May 2006 Bitdefender developed a new technology, B-HAVE, to reduce dependency on virus signatures through proactive detection of unknown threats. This technology is based on a behavioral analysis in a virtualized environment.
To determine whether a program is malicious or not, this technology makes use of a virtual PC in which files are executed and analyzed. The virtual PC includes a set of virtual hardware devices, mimicking the configuration of a typical PC. B-HAVE checks for characteristics known to be associated with malware. A program may be deemed to be malicious if it attempts to modify certain files, read from or write to a sensitive area of the memory or create a file that is a product of a known virus. When attempting to use a non-trusted program, B-HAVE delays the launching until the program’s behavior and characteristics are analyzed and catalogued in the virtual environment. If no malicious actions are detected, B-HAVE starts the program normally; if a suspect conduct is present, B-HAVE automatically quarantines or deletes the application
