We have tons of new features and our detection rates improve each day. I don't think it's any secret that Webroot totally did away with the Spy Sweeper product several years ago. We literally built the SecureAnywhere product from the ground up -- including classification of both whitelist and blacklist files.
If you tried SpySweeper or the SecureAnywhere Beta from a couple of years ago -- everything is completely different since then. Admittedly, there were lots of bugs and features that didn't work as expected when we first released a few years ago, but all that has been corrected now.
So if you haven't given us a try in a while, you can get a free download trial from the Webroot website. We can run along side of your other AV.

And regarding the Zero-Day comments -- Let's face it, there is NO product that blocks truly unique malware on the very first day it's released. That's just the nature of the beast. But with our roll-back features, keystroke / screenshot blocking 'Identity Shield', plus other features that help keep your information secure, Customers can rest assured that Webroot will protect their system even if infected with Zero-Day malware.
Furthermore, if a customer is infected with a virus that we are not removing, they can give us a call or contact us via the community and we'll be able to use our Threat Intelligence Network to find, classify, and have the product remove the suspicious file -- and customers won't have to wait for a signature release in order to be protected.
So before you bash us, give us a try -- you'll be impressed.
