Antivirus and anti-spyware engine
State of the art scanning engine provides reliable protection against viruses, spyware and other forms of malicious software.

Real time anti-rootkit protection
Unique on access technology checks all kernel-mode drivers that the operating system is loading for signs of rootkit behavior. This enables even unknown rootkits to be detected and stopped before they can do any damage.

avast! Sandbox
Enables potentially exploitable programs (such as web browsers) and/or suspicious executables to be run in a safe, virtual environment. The avast! Sandbox is unique as it runs on both 32 and 64bit platforms.

avast! Community IQ
Most samples we process come from sensors deployed throughout the avast! community in the Behavior shield and anti-rootkit modules. This is a unique source of data made possible only thanks to our huge user base. 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.

Code emulator
When a suspicious executable is encountered (during both on-demand and on-access scanning), avast! is able to emulate the program鈥檚 code in an isolated environment. The code emulator is used for two purposes. First, it is used for generic unpacking. Secondly, it is used in the heuristics engine. Technically, this is done using dynamic translation, a method much FASTER than traditional emulation techniques.

Heuristics engine
Starting with version 5.0, avast! features a new heuristics engine designed to proactively Detect malware undetectable with normal definitions. The heuristics engine is able to cover both binary (executable) and script malware. you can free download Avast! Professional Edition 5.1.822 Beta / 5.0.677 now.
