Avast Antivirus

Based on the award-winning avast! antivirus engine, avast! antivirus contains all of the features you would expect in a modern antivirus program. It incorporates anti-spyware technology certified by West Coast Labs’ Checkmark process, as well as anti-rootkit and strong self-protection capabilities, but now provides even faster scanning with improved detection ability. It contains several real-time “Shields” which continuously monitor your email and internet connections and check the files on your computer whenever they are opened or closed.

avast! antivirus now also comes with a completely revamped user interface for easier scanning. avast! Pro antivirus offers a number of additional features, including a script shield and a process virtualization module, while avast! Internet Security comes with an antispam filter and built-in firewall. Once installed, avast! runs silently in the background to protect your computer against all known forms of malware. You don’t need to do anything else – just install and forget!

Core and detection:

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! 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 programs 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:

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.

Potentially unwanted programs detection:

avast! detects potentially unwanted programs, such as remote admin tools and commercial key loggers. Custom rules can be set for dealing with these types of programs.

Scanning:

Boot-time scanner

Allows you to scan your computer for infections before the operating system has started and before a virus can be activated (32-bit operating systems only).

Command-line scanner:

Enables you to run a scan directly from the command line.
