Both coins (XAGON and QUEDOS) were created by my service over a month ago. They were ordered by different individuals, but seeing as they were released on the same day, and have similar whitepapers, it's not too difficult to see they're being pushed by the same person/group.
I checked, and it doesn't look like there were any modifications made to the client after I compiled, so they should be clean. Here's the VT links:

I've been dealing with false positives like these for a
very long time. BitcoinMiner is the one that always persists, but every now and then some D-List antivirus will decide throw a very nasty sounding false positive.
Artemis is a heuristic detection tool by McAfee and isn't indicative of anything in particular. It just means something is "suspicious", but given McAfee's track record as the worst antivirus ever, I wouldn't put too much stock in it. It certainly doesn't "basically disable almost all functions of your machine", that's just pure FUD.
Trojan.StartPage.Win32.26934 is absolutely a false positive by a crappy AV vendor (who has ever heard of zillya before?) and is incredibly easy to verify since the payload of that particular trojan is that is changes your home page. Run the client in a VM and you'll see it does no such thing. Also refer to the often overlooked behavioral information of both clients, and you'll see nothing out of the ordinary:

this gem after ocminer exposed him with this thread. Amusingly enough, he claims that I exposed him, and he now wants to fight me. A true internet tough guy, if there ever was one.
tl;dr Both coins are free of malware - any detection is simple a false positive. So if you've ran them, don't panic and nuke your computer. That being said, I'd still stay away from both of these coins for every other reason mentioned above.
