Why choose this product?

avast! Pro Antivirus employs complete virtualization technology to increase your protection. Any application can be run in the virtual Sandbox environment, to prevent attackers from reaching your PC. What's more, the avast! SafeZone™ gives you an isolated desktop fortress for even more sensitive operations.

Prevent interruptions

Automatically detect full-screen applications with Silent/Gaming mode, to disable pop-ups and other notifications without compromising security.

Keep unwanted scripts away

Our Script Shield detects malevolent scripts hidden in web pages and prevents them from hijacking and damaging your computer, while our Web Shield scans all visited web pages, downloaded files, and java scripts.

Stay proactive

Our heuristics engine proactively finds malware that is undetectable with normal definitions and virus signatures.

Clean your PC before Windows even starts

Our unique boot-time scanner cleans your PC before the Windows operating system can start to activate any viruses or malware beneath (now applies also to 64-bit Windows 7 and Windows Vista).

Please also note that avast! will not run properly if you have other antivirus software on your PC.

Core Technologies

Antivirus and anti-spyware engine Improved

Innovative scanning engine protects against viruses, spyware, and other malicious agents.

Real-time anti-rootkit protection

Prevents stealth malware (‘rootkits’) that, when loaded by the computer’s OS, are invisible to ordinary scanners.

Silent Firewall Improved avast! Internet Security only

Stops hackers, using heuristic and behavioral analysis and a white list of safe applications.

Antispam Improved avast! Internet Security only

Comprehensive spam and phishing filter, which works as a plug-in to MS Outlook and a generic POP3/IMAP4 proxy for other email clients.

avast! WebRep New

Provides website reliability and reputation ratings according to community-provided feedback.

avast! CommunityIQ

Our technology uses a global network of sensors to provide us with data taken (anonymously) from the actual web-browsing experiences of an opt-in group of avast! users. This info is then used to protect all avast! users with the most up-to-date information on viruses and infected websites.
Because of avast! CommunityIQ, avast! has discovered 275,738 infected websites and protected 150,751,206 people from visiting them in the last 30 days.

Hi-Tech Features

Boot-time scanner Improved

Scans your computer for infections before the OS can start to activate any viruses beneath it (now applies also to 64-bit versions of Windows 7 and Windows Vista).

avast! SafeZone™ New

Opens a new (clean) desktop so that other applications don’t see what’s happening – perfect for banking or secure ordering/shopping – and leaves no traces once it’s closed.

AutoSandbox New

Prompts users to run suspicious applications in the virtual Sandbox environment.

avast! Sandbox

Provides an extra layer of security for you to run your PC and its applications in a virtual environment – where any attacks are thus targeted (instead of your real PC).

OS supported:

  • Windows XP SP2+ 32-bit
  • Windows Server 2003, Vista, 7 (32-bit and 64-bit) only RTM versions are supported (Windows 7 SP1 RC is currently also supported)

OS not supported:

  • Windows 2000
  • Windows XP 64-bit (with any SP installed)
  • Windows Server 2003 64-bit

Intelligent Scanner

Reduces the number of required file scans up to 80% through a white list of safe applications. Files identified as safe are not rescanned unless they change.

Silent/Gaming Mode

Automatically detects full-screen applications and disables pop-ups and other notifications without compromising security.

Green computing

Leaves a minimal “footprint” due to its efficient and effective technology.

avast! Real-time Shields – a team of 24/7 guards

File System Shield

Real-time scanning of opened/executed files.

Mail Shield

Scans all incoming/outgoing email for malware (a special plug-in is used for MS Outlook).

Web Shield Improved

Scans all visited web pages, downloaded files, and java scripts. Thanks to the intelligent stream scanning feature, the Web Shield doesn't slow your web browsing.

P2P Shield/IM Shield

Checks files downloaded via P2P programs and while using IM or “chat” programs.

Network Shield

Protects against network-based viruses with two main components: a URL blocker for malicious URLs, and a lightweight intrusion-detection system.

Script Shield Improved

Detects malicious scripts hidden in web pages and prevents them from hijacking and potentially damaging your computer.

Behavior Shield Improved

Stops ‘zero-day’ threats and unknown malware before virus definitions have been obtained.

Others

64-bit support New

Supports the 64-bit architecture platforms of Windows 7 and Windows Vista.

Heuristics engine

Proactively finds malware undetectable with normal definitions and virus signatures.

Code emulator

Uses dynamic translation (a method much faster than traditional emulation) for both generic unpacking and within the heuristics engine.

Automatic processing

Infected files are processed automatically, without requiring user instructions.

Smart virus definition updates

Incremental updating minimizes the size of regular update files.

Fast application of updates

New format for the virus definition file means faster updates and reduces demand on CPU/memory, for uninterrupted computing.

Multi-threaded scanning optimization

Allows the splitting of large files between cores, which accelerates the scanning process on new multi-core CPUs and makes avast! run even faster.

Wake-up/Scheduled scanning

Schedule scanning at night or whenever you don’t need to use your PC.

Command-line scanner

Runs a scan directly from the command line.

What people say about avast

"Both my wife and I really like the simplicity of AVAST and feel reassured when the AVAST voice notifies us when the updates have been completed rather than having to go through a sequence of button pushing to clear the screen. I have also noticed that our computers are allowed to do what they do best, without the irritating interruptions or slow downs."
