AVG has started classing SABnzbd+ as a "Potentially harmful program Logger.FNY"
I woke this morning to find SABnzbd+ wasn't running and the exe missing.
I have sent SABnzbd+ to AVG as a false positive.
This post is just FYI
I have had the same with AVG yesterday (a friend of my also).
I reinstall SABnzbd and get some updates from AVG and the problem seems to be over, but you never know.
