For those that want deeper privacy protection

Tweet to your heart's content, shop, or bank safely and 'like' - well, anything you like. Internet Security's intelligent threat-detection keeps your identity safe online, and now adds an extra layer of anti-ransomware protection for your most important files and photos.

Keep hostage-takers off your files

Hackers demand an average of $643 from ransomwarevictims. Internet Security now walls off your private files & photos so they can't be encrypted and held hostage.

Avoid fake websites

Hackers can easily create a replica of your banking site to steal your logins and passwords. Internet Security encrypts your data so your information stays safe.

Spot scam emails

Today's phishing emails are not as obvious as "you've won the lottery." Internet Security stops more than the usual strange text and sender.

Firewall your data

The data sitting on your PC is the key to identity theft. Internet Security's Firewall is the strong gatekeeper you need to stop hackers from accessing it.

Take a look inside

Internet Security offers many layers of protection to keep you safe and your devices running smoothly. All of the advanced features below are included in your Internet Security software.

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.
