Hi Bob and drhayden,
I've also installed BigFix and set Automatic Updates to notify only as mentioned in the article Bob linked to.
Seems like a pretty solid concept but I'll reserve judgment for a while - after evaluating 406 Fixlet Messages it finds no issues on my computer. I guess I'm too diligent about keeping things patched.
I'm not following the author's advice to disable it so its currently using 6092k ram running in the background (was 11,998k for some time after installation). This seems like a better way to test the program.
The EULA contains, in part, the following wording
"In addition, BigFix licenses third parties the technology necessary to examine elements of your computer using BFAST, which interaction can only be accomplished with your permission. In addition, you have the ability, as part of the BFAST technology to review any and all information being sent by you to such third party licensee. BigFix assumes no liability with regard to how such third party licensees employ BFAST, or use any information about your computer obtained through the use thereof."
I'm not 100% OK with that but trying it out anyway.
