"Still the Finest Overall Package"4.0 starson by dlauber
Pros: Excellent live tech support based in the USA. They pay attention to user suggestions and incorporate them into the new product. Free update to new version during license period. Does not slow down your computer.
Cons: Integration with Mozilla's Thuderbird email is a bit spotty. False positives tend to involve "not-a-virus" being identified incorrectly,
Summary: After suffering through a decade of Norton and then Trend Micro's PC-Cillan, we've been using Kaspersky Internet Security for 3 years. Sure, we sometimes run into a problem, but the phone tech support has been fantastic with actual follow-up. All in all, KIS has worked for us better and more reliably than its competitors. I recommend it to all my clients.
