I have been using Norton Internet Security for the past 6 weeks, and I'm glad to say that it has not caused any problems with Band-in-a-Box.

I purchased this Toshiba laptop with i5 processor recently to support my new BB 2011. The Norton limited trial was installed. I have installed BB from the hard drive and have installed updates from the web site twice without interference from Norton. So, maybe the problem people were having with Norton Anti-Virus has been resolved.

Now that the Nortor trial period is over I am crossing my fingers as I install McAfee Total Protection 2011. (I chose McAfee because I could get three licences almost for free after mail-in rebates.)

My old computer, where I first installed BB 2011, had last year's version of McAfee, and also had no conflicts with BB.

Had I seen this discussion sooner, I may have tried Microsoft Security Essentials.
