Protect yourself against the latest malware attacks
Every day, over 315,000 new items of malware are unleashed by cybercriminals. If you’re going to protect your PC and your confidential information – you need a security solution that keeps up with the very latest threats.

Get security that won’t compromise performance
While you need to ensure your PC – plus the precious information you store on it – are fully protected, it’s no good having security software that ruins your PC’s performance… so you can’t enjoy your digital life to the fullest extent.

Prevent theft of your money & financial information
Online banking, shopping and payment systems have helped to simplify a host of everyday tasks – but they’ve also introduced serious security risks, including the potential theft of your passwords, your account details and your cash.

Don’t let the ‘Identity-Thieves’ take control
Imagine the chaos that can result if someone accesses your confidential information. If criminals capture your passwords and personal data, they can take on your ‘digital identity’, defraud you of money and cause a range of long-term problems.

Ensure your kids can enjoy the Internet… in safety
Internet threats can be scary for security-minded adults – let alone innocent children that trust what they see and who they communicate with. However, as the Internet is also a powerful educational tool, you need to enable secure access for your kids.

Stay safe & manage costs when you’re out & about
When you use public Wi-Fi, it’s easy for criminals to intercept your emails, passwords, credit card numbers and more. As well as taking care to protect your information, you also need to avoid excessive charges from Wi-Fi & 3G / 4G network operators.

Top detection rates of viruses and malware have been proven by independent labs.

Unwanted applications. Stop them before they take control.

Some programmes contain adware, they install toolbars and modify your system settings. They’re not malicious like trojans or worms but they can change your browser settings, alter your home page and direct you to another search engine by default. BullGuard’s unwanted app tool flags up these programmes and stops them from changing your settings.

BullGuard Parental Control is a powerful and easy-to-use tool that helps you protect your children online.

And here’s more: your back-up data is easily accessible whenever you want to view it or restore it to another computer or even your smart phone.

Firewall. Keep out intruders.

Protect your computer from unwanted hackers and identity thieves with this first line of defense. The firewall protects you against network attacks and prevents cyber crooks from entering your system.
