Did this detect a real virus or is it fake?

In the past few days, I've had 2 random occurrences on certain sites where a new tab would pop up with text in the middle of the screen saying Microsoft Security Essentials has detected potential threats and I need to clean out my computer immediately to prevent the system crash. There is also a something that says "clean computer" that can be clicked. Well as far as I know I don't even have MSE. I have Avira and Malwarebytes so I'm assuming this is just some BS scam. What exactly is it?

Ok this is just bizarre. I don't know if this means anything, but I was installing Max Payne 3 on Steam when I got the pop up in the browser about the viruses. Well I cancelled the install in order to do the Scans and once the virus scans finished I went to install MP3 all over again.

Well about 20 percent through my install, Avira popped up in the corner saying it detected something. I looked at the Virus information and Avira thinks it found a Trojan. It says the Object is "MaxPayne3.exe" and the detection is "TR/Crypt.XPACK.Gen2"

Now I know Avira is widely known for false positives. (Every time I scan it gets like 40 warnings from my Witcher 2 updates) So could this be a false positive?

To my relief I found something that suggests it's a false positive.
