There is a *new threat floating around Facebook. It's another one of those "See Who's Viewing Your Profile" scams. I'm surprised so many people are dying to see who's viewing their profile.
Antivirus alone is no longer enough though. Threats come in all shapes and sizes and “virus” no longer covers the gamut of threats out there. Once a system is compromised, it can be very difficult to regain control over. The most effective tool in regaining control over a compromised system, in our experience, is Malwarebytes’ Anti-Malware Pro.
Running McAfee? Think you're protected? You're not. Don't be fooled into installing "Antispywarebot" - it's a virus.
