So, I stopped CGminer this evening, and when I relaunched CG, Avast AV is telling me it has a rootkit!
Then it blocks it! So I tried to re-extract from the zip, and Avast pops in and blocks it before unpacking the files!
I don't know if this is cause for alarm, or if the Avast people have some bad info!?!
This is the first occurrence, and does it with all versions 1.5.1-present. (These are the only ones I have, so I don't know about older versions!)
