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.
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.
Provides website reliability and reputation ratings according to community-provided feedback.
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 89 082 infected websites and protected 123 176 306 people from visiting them in the last 30 days.
Scans your computer for infections before the OS can start to activate any viruses beneath it (now applies to Windows 7 and Windows Vista).
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.
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).
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 XP 64-bit (with any SP installed)
Windows Server 2003 64-bit
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.
Automatically detects full-screen applications and disables pop-ups and other notifications without compromising security.
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.
Scans all incoming/outgoing email for malware (a special plug-in is used for MS Outlook).
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.
Protects against network-based viruses with two main components: a URL blocker for malicious URLs, and a lightweight intrusion-detection system.
Detects malicious scripts hidden in web pages and prevents them from hijacking and potentially damaging your computer.
Stops ‘zero-day’ threats and unknown malware before virus definitions have been obtained.
Supports the 64-bit architecture platforms of Windows 7 and Windows Vista.
Proactively finds malware undetectable with normal definitions and virus signatures.
Uses dynamic translation (a method much faster than traditional emulation) for both generic unpacking and within the heuristics engine.
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.
Schedule scanning at night or whenever you don’t need to use your PC.
Runs a scan directly from the command line.
