I get the same thing too. Avast says it's infected with Win32:Malware-gen. It just deletes the infected "arkenstoned.exe" file, and the wallet seems to run fine without it.

Anyone have any suggestions as to whether or not it's worthwhile to mine a coin who's developers added a virus into the package? I know just like University Coin this is one I won't touch.
No virus into the package. Almost all coins have a problem with antivirus programs.
Have to disagree with you big time on that one. I've got 191 wallets installed on my computer, Arkenstone is one of only 3 I've had virus warnings for. There's no reason for a false positive. I'm not a super expert or anything like that, but I can't think of why a cryptocoin would set off a virus flag unless it's infected.
