Probably nothing serious, but this is what virustotal found:
File name: Appcoin-Qt.exe
Detection ratio: 1 / 49
Analysis date: 2014-02-23 21:39:19 UTC ( 5 minutes ago )
Antivirus Result Update
Bkav HW32.Laneul.gems 20140222
I looked it up more, and it seems like a lot of security systems call it a backdoor, so I would get rid of it ASAP.
EDIT: Nvr mind, I guess not.
Thanks for the feedback.
The scan result and the detected issue is pretty common and can be found in many alternative cryptocurrencies. It's known by many experienced altcoiners and it's been confirmed to be harmless.
