HAXM Hotfix has a virus?

I tried downloading and installing this HAXM hotfix for my Windows 8.1, but my Webroot virus software detected W32.ROGUE.GEN. Is my virus checker reporting a false flag, or is this file really infected?

My system was crashing when I used HAXM trying to emulate an Intel Atom (x86). I think I had it configured properly but I read that I need to install a hotfix for my Windows 8.1 machine. I'm tired of Win 8.1's issues so I'm going to try to get my Windows 7 machine up and running.
