downloaded MxO from this site, and now have a virus!

Agreed. My virus scanner is constantly updated and paid for...which is important, since so many malware coders out there target the freeware anti-virus programs and engineer their viruses and spyware to defeat them, counting on the vast majority of net users to be too cheap to actually pay for an anti-virus and thus financially support the anti-virus coders. There's a huge difference between AVG Free and the paid-for AVG Anti-Virus--both of which I've had. And guess which one found a heap of junk on my hard drive that the other overlooked after I forked over about $40 at Walmart and made an upgrade.

And while under full protection from malware, I downloaded and installed the emulator's files without incident.

So you'd better break out the Scooby Snacks and keep looking for the real malware executable, Smokewood.
