-- Get a good quality anti-virus. With the rafts of gaming malware out there, and the increasing sophistication of the malicious software, you'll need some level of protection against it. You'll need AV that goes beyond signature-based detection to look at file reputation, if you want to stop the smartest malware getting on your system.
-- Be careful who you befriend. It's easy to make friends in virtual worlds today, but not all are doing so innocently. Beware anyone who asks for your personal details, as they may want to do more than just contact you.
-- Only download titles from legitimate sellers. If you're downloading an illegal copy of a game, you aren't just breaking the law. You're risking getting malware on your machine, as crooks often disguise game files as malicious software.
