I personally hate false positives. Of course, at the time, you don't know they are false positives. That's the problem! Every time my antispyware or antivirus tells me it has found some malicious program, my heart leaps. Even if it's something I can dimiss with a glance or with some investigation..... And those that I can't, induces within me a sense of panic. The uncertainty, of whether your digital home has being breached, hanging like a heavy weight over me. I can't sleep, can't eat, until I have dismissed the possibility.
