Core and detection
Improved 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.
New Code emulator

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.
New 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.
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.
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).
Wake-up for scan

Microsoft Windows is woken from sleep or hibernation mode, performs a scheduled scan, then returns back to sleep mode.
Scheduled scanning

Allows users to define the scan time and files to be scanned.
New 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.
Shields
New Behavior Shield

Monitors activity on your computer using a number of sensors (file system, registry and network based) and reports/blocks any suspicious behavior.
Behavioral Honeypots

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.
Mail Shield

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, ….)
Web Shield

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.
P2P Shield

Checks files downloaded using P2P programs. - ABC, Ares, Azureus, BearShare, Bit Torrent, BitComet, BitLord, BitPump, CZDC++, Direct Connect, eDonkey, eMule, iDC++, iMesh, Kazaa, Kceasy, LimeWire, Morpheus, Opera's DC++, Overnet, Qtrax, Shareaza, SoulSeek, StrongDC++, uTorrent, Vuze, WinMX, Winny2, Zultrax.
IM Shield

Checks files downloaded while using instant messaging or “chat” programs. - AIM (AOL Instant Messenger), Gadu-Gadu, gaim/Pidgin, Google Talk, ICQ, IM2 Messenger, Infium, Miranda, mIRC, MSN/Windows Messenger, Odigo, PalTalk Messenger, Psi Jabber Client, QIP, QQ, SIM, Skype, Tlen, Trillian, WengoPhone, XFire, Yahoo! Messenger.
Network Shield

Provides protection against network-based viruses. The module has two main components: a URL blocker, designed to block malicious URLs (as defined by the Virus Lab), and a lightweight intrusion-detection system.
Updates
Smart virus definition updates

Incremental updating system minimizes the size of regular update files.
New Fast application of updates

New format for the virus definition file speeds up application of updates into avast! 5.0 and reduces demand on CPU/memory, resulting in uninterrupted computer use.
New format for the virus definition file means faster updates and reduces demand on CPU/memory, resulting in uninterrupted computer use.
Gaming
New Silent/Gaming Mode

New Silent/Gaming Mode automatically detects full-screen applications and disables pop-ups and other on-screen notifications without degrading security.
Optimized for latest Intel Core i7 CPUs

Critical sections of the avast! scanning engine code have been optimized to deliver unrivaled performance on the latest Intel chips.
CPU optimization
New Multi-threaded scanning optimization

avast! runs faster on new multi-core CPUs. A new avast! feature allows the splitting of large individual files between cores, accelerating the scanning process.
Green computing

Reduced demands on the disk drive result in lower energy consumption.
Miscellaneous
avast! iTrack

Real-time graphic scanning reports.
Brand new Graphical user interface

Easy to navigate graphical interface.
Automatic processing

Infected files are processed automatically without requiring user instructions.
