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.

Antivirus. Effectively catches all viruses.

Our Antivirus includes Behavioural Detection, which spots new viruses because of the actions they take on your computer and stops them before they can do damage. Together with Signature-based Detection, which identifies the ‘signatures’ of known malware, you gain a multi-layered defence system for your PC that’s virtually impenetrable. 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.

Powerful Parental Control. Protect without nagging.

BullGuard Parental Control is a powerful and easy-to-use tool that helps you protect your children online. You can block access to suspicious websites, put search filters in place, limit their time online and even monitor their activity.

Advanced Backup. Easily back up, recover and share files.

We’ve included 5GB of FREE online storage so you can keep your important data, photos, music and more safe. You can choose what you want to back up and how often, or just set the feature to auto backup. You can even back up content directly from folders with one click. 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.

Spamfilter. No spam. No scam.

BullGuard Spamfilter keeps out junk mail and email scams, like phishing attempts, virus spreading and foreign language spam. You can also customize filters to block emails you don’t want to receive.
Safe Browsing. All web sites checked.

Some websites have malicious code hidden in them. Or they are used to launch phishing attacks. The BullGuard protection software checks the websites that come up in your searches and lets you know which ones are safe and cautions you about those that can’t be trusted.

PC Tune Up. Keep your PC running smooth and fast.

You’ll never have to wait again to get your computer up and running. BullGuard’s PC Tune Up removes unnecessary files and frees up memory so your computer runs faster.
