Security programs, rather annoyingly, have different ways of saying 'zap the ruddy thing!'.
While it's theoretically possible to get a 'false positive' with any security program (meaning that you could accidentally 'zap' something you want to keep) it's actually very unlikely to happen. My policy is always to choose 'delete', 'quarantine', or whatever looks the most lethal whenever any unknown threat is shown. (In the very unlikely event of something important accidentally getting zapped it can always be reinstalled anyway).
