I haven't used it, but I generally have a dim view of security software provided by ISPs (after an excruciating experience with AT&T's bad excuse for a security suite.)
However, it looks like some people like it. At least one reviewer
had serious computer slow-downs and crashes after installing it, though.
The suite is from CA, and includes software that would otherwise cost you around $50. SO the underlying technology seems to be sound.
Hmmm, it looks like I've been no help at all in actually deciding! But at least I got to take up some space and learn a bit about a new security suite.
