avast! Free Antivirus : For normal use
Antivirus and anti-spyware engineState 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.
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. 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.
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.
Potentially unwanted programs detection
New in version 5.0, avast! now 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.
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).
Wake-up for scan
Microsoft Windows is woken from sleep or hibernation mode, performs a scheduled scan, then returns back to sleep mode.
Allows users to define the scan time and files to be scanned.
avast! Intelligent Scanner Can reduce the number of required file scans by up to 80% through a white list of proven safe applications. Files identified as safe are not rescanned unless they change.
Monitors activity on your computer using a number of sensors (file system, registry and network based) and reports/blocks any suspicious behavior.
avast! sensors identify and monitor suspicious file activity on selected computers, automatically submitting files to the Virus Lab for additional analysis.
File System Shield
Real-time scanning of opened/executed files.
Scans all incoming/outgoing e-mails for malware. For MS Outlook, a special plug-in is used. Other email clients are protected by a generic POP3/IMAP4/SMTP proxy. New in version 5, the proxy also supports scanning of SSL communication (gmail.com, sympatico.ca, ….)
Scans all visited web pages and checks all files, pages and java scripts downloaded from the internet. Thanks to the Intelligent Stream Scan feature, the Web shield doesn't slow down your web browsing.
