European PC users have won the honourable title of caring the least about security. Data from CipherTrust shows that Europe leads the way in the number of zombie PCs: 26 per cent of all PCs infected are located there, followed by the US (20 per cent) and China (15 per cent).

Zombie PCs are computers that have been infected by a worm or virus and are at the control of hackers. They rent them out to send spam or launch DDoS (distributed denial of service) attacks.

It's an embarrassing result for Europe, especially because there are some simple ways to prevent your computer from being turned into a zombie. Praying is one of them, followed by running anti virus software, a firewall and staying up to date with the latest patches.

Oh, and don't open every email attachment that promises pictures of naked 16 year old girls.
