Why choose avast! Internet Security?

avast! Internet Security provides complete antivirus, anti-spyware, antispam, and firewall protection, complemented now by new avast! SafeZone™ technology. It creates an isolated virtual desktop, invisible to any possible attacker, where you can do your online shopping and banking securely.

Shop and bank online with total privacy

avast! SafeZone™ opens a new (clean) desktop so that other programs don’t see what’s happening – and it leaves no history once it’s closed. 

Worry-free social networking and web surfing

Our award-winning and certified antivirus engine and shields stop even previously unknown threats – for peace of mind when you chat or spend time on Facebook, Twitter, or other websites.

Prevent identity theft

Our silent firewall stops hackers and other unauthorized entry attempts to your PC, to keep your data where it belongs – safe and sound.

Keep your email inbox safe and clean

Internet Security’s antispam feature blocks both spam and sophisticated “phishing” attempts, to keep you from clicking “harmless” links that really can cause damage.

Antivirus and anti-spyware engine 

  • 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 

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


  • 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 

  • 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 62,887 infected websites and protected 126,296,177 people from visiting them in the last 30 days. 

Boot-time scanner 

  • Scans your computer for infections before the OS can start to activate any viruses beneath it (now applies to Windows 7 and Windows Vista). 

avast! SafeZone™ 

  • 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. 


  • 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. 

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 

  • 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 

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

Behavior Shield 

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

64-bit support 

  • 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.

Operating Systems Supported

  • Windows 7
  • Windows Vista (any Edition excl. Starter Edition)
  • Windows XP Service Pack 2 or higher

Minimum Hardware Requirements

  • Processor Pentium 3
  • 256 MB RAM
  • 380 MB of free hard disk space

Please note that avast! Internet Security runs only on PCs with Windows XP and newer. Older Windows operating systems (Windows 95/98/ME/NT/2000) are not supported.

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