We know you're excited about the possibility of a GTA V release on PC...and so do spammers. A new spam email has been circulating which pretends to be an invitation for a Windows beta test for GTA V. It provides a "code" in the form of a zip file, which actually contains malware.
If you get such an email, don't let your excitement over GTA V cloud your judgment. We'll let you know if we hear anything about a legitimate beta, and in the meantime, be wary of any suspicious emails.
