I agree. Get rid of it and get a refund since it clearly didn't work for you. Aside from there being no real need for AV programs on a Mac (yet at least), Norton is reigning king of the false-positives. McAfee probably hasn't made any significant changes to their scanning engine since the Windows95 days, so it's a slow and inefficient mess. Sophos is just a joke. Kaspersky has been on a downhill trajectory for at least the past few versions with feature creep becoming a serious issue. So I say dump all of them. They aren't doing you any real good on a Mac (if you're running Windows inside a VM, then Windows should probably have an AV program), so why waste money? If you have whatever it is these places charge for a subscription fee burning a hole in your pocket, I can tell you about the Jimmy Greystone Personal Wellness Prorgram, where all proceeds go to benefit me. You get about the same level of benefit either way, but I'm at least being honest about my intentions, and I'm not cluttering up your system with a bunch of useless software.
