Take a look inside

Internet Security is more than a one-trick pony. It comes with many tried-and-tested security measures to keep you safe and your devices running smoothly.

Intelligent antivirus

Detects all kinds of nasty threats, from viruses to malware. Yes, even spyware, ransomware, and phishing attacks.

Smart Scan

The ultimate time-saver. Check your PC and network for all kinds of issues in just one easy click.

Home Network Security

Is your router set up properly? We’ll tell you. Otherwise, anyone can break into your network and anything connected to it (like your computer, phone, or printer).

Browser Cleanup

Get rid of mystery toolbars, add-ons, and extensions that were installed without you noticing – and without your permission.


You lock your front door to keep thieves out of your home – so why should your computer be any different? Firewall keeps you safe from all kinds of intruders.


Too many passwords, none of which is safe? It’s fairly common. Remember just one, and Passwords will take care of the rest.


Ever downloaded a file from a shady server and suspected it’s trouble? Test files in a sealed space first, and keep the rest of your PC safe.


Your router settings can be changed to connect you to a fake site. Why? So hackers can steal your banking details. SecureDNS keeps your online banking safe.


Spam isn’t just annoying. It can be dangerous, too. Internet Security keeps you – and your money – safe from threats like phishing emails.


Pay and bank safely, without anyone seeing your details. SafeZone creates a protective space that hackers - and anyone else – can’t access.
