Our avast! Free Antivirus often outperforms our competitors´ paid-for products and is the minimum protection anyone should have against viruses and spyware.

But if you shop or bank online and store sensitive data on your PC, we recommend our maximum, next-generation protection, avast! Internet Security.

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.

avast! is lightning fast

avast! has been proven again for its great scanning speed. Anti-Malware Test Labs tested 16 antiviruses and avast! received the highest honor, the Platinum Performance Award. Accelerate your PC with avast!

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."
