I have had a "threat secured" notice pop-up more than a dozen times in the past 24 hours. "JS:LockyDownloader [Trj] and now it's Quarantied in the Virus Chest." I see the details; and have the option to view the virus chest. It is always empty. The threat is always from the same source. Is this some sort of bot sending repeated instances of the same contaminated message? Or is this a false positive? How do I make it stop?
