Custom rules can be set for dealing with these types of programs. Potentially unwanted programs detection New in version 5.0, avast! now detects potentially unwanted programs, such as remote admin tools and commercial key loggers.The heuristics engine is able to cover both binary (executable) and script malware. New Heuristics engine Starting with version 5.0, avast! features a new heuristics engine designed to proactively detect malware undetectable with normal definitions.Technically, this is done using dynamic translation, a method much faster than traditional emulation techniques.
Secondly, it is used in the heuristics engine. The code emulator is used for two purposes. When a suspicious executable is encountered (during both on-demand and on-access scanning), avast! is able to emulate the program�s code in an isolated environment. Most of the collected samples are analysed by a number of automated processes and only a small fraction of the samples need to be processed manually by our virus analysts. This is a unique source of data made possible only thanks to our huge user base.
Most samples we process come from sensors deployed throughout the avast! community in the Behavior shield and anti-rootkit modules. The avast! Sandbox is unique as it runs on both 32 and 64bit platforms. This enables even unknown rootkits to be detected and stopped before they can do any damage.Įnables potentially exploitable programs (such as web browsers) and/or suspicious executables to be run in a safe, virtual environment. Unique "on access" technology checks all kernel-mode drivers that the operating system is loading for signs of rootkit behavior.
