As you can tell from my usage tip, I have used Webroot products before. Mac Washer for OSX does all that it claims, despite the small gitch that is in version 1.
Take into consideration that this is the first version of this software for OS X, Webroot is aware of this problem, and will be issuing a fix very shortly.

It is a solid, sturdy piece of software that does as advertised. I am rating favorably because it performs as promised.
