Your all-inclusive protection.
Our top-selling suite secures your data, identity, and sensitive financial transactions in its unique SafeZone – and keeps hackers out with its Firewall.

Online or offline, you’re totally secure

Secure your financial transactions.
Prevent having your credit card or online banking data hacked and your money stolen. Use SafeZone, an Internet Security feature that secures sensitive transactions. Set your favorite banking or shopping sites to automatically launch SafeZone to ensure that all of your sensitive financial transactions stay private.

Make your computer a data fortress
Your private data shouldn’t be available to anyone but you. So the silent firewall in Internet Security blocks hackers from stealing sensitive personal data from your PC. This new version was rebuilt to make faster decisions, work even better with Windows, and fully support IPv6.

Say "Goodbye" to spam & phishing scams
The majority of spam includes harmful ‘phishing’ links built specifically to exploit your PC or credit card data. This type of phishing email tries to convince you it’s from a legitimate sender. Our anti-spam technology filters out such nuisances to save your time and protect you from potential headaches.

Did it break? Fix it!
If anything nasty happens to your computer and some malware blocks access to your avast!, you fortunately were able to create an image of your avast! setup on a USB stick or CD/DVD ahead of time, which will help you restore the PC to its normal functions.

Intelligent antivirus, anti-spyware, & anti-malware
Not just a marketing phrase! Our DynaGen-powered antivirus streams hundreds of tiny real-time updates to your PC’s virus database each day, to catch new malware faster. Its decisions are based on artificial intelligence that works inside the algorithm responsible for analyzing suspicious files.

Run shady files in a virus-proof environment
Unsure if the file you just downloaded is safe? Run it in the Sandbox, a virtual environment where you can run even the most heavily infected files safely. But you’ll know if it’s safe anyway, with our FileRep (file-reputation scanning) technology.

Our crowd in the cloud
avast! CommunityIQ is one of the world’s fastest signature-based malware data sources. This early warning system is based on data from tens of millions of our customers who – anonymously – share any new pieces of malware they encounter.

SYSTEM REQUIRED : 
You need at least Windows XP (with SP2) installed. Windows Vista, 7, 8, and even 8.1 are fully supported (unless your device runs the Starter or RT edition) in both the 32- and 64-bit variant. A 10-year old Pentium 3 processor will do, with 128 MB RAM and 600 MB of hard-drive space. And now imagine the stellar performance with your new hardware!
