I just had to dump TrendMicro PCcillin. It seemed incapable of distinguishing cookies (that are a matter of course in surfing) and spyware and/or viruses. My computer time with Trend Micro PC cillin consisted mostly of grabbing the mouse upwards of 20 times an hour to close warning box pop-ups.

Once I dumped the PC cillin and went back to Norton, not only do I not have the annoying pop-ups, my computer is faster as well.
