Clean My Mac detects Acorn as having malware

I'm sure it's not. I can't imagine that hackers have been able to corrupt a download from GitHub. But I thought this might be useful information. Detected threat: OSX.Pirrit Malware

Hmm, I'm wondering if the malware infected Acorn while it was on your computer. Can you download a fresh copy and run it again?
