36 hours and still scanning? Norton Internet Security 5 for Mac

Just installed Internet Security 5, ran full system scan that included the Mac OSX/Version 10.7.3, and it's "Time Machine".  Why is this scan still running after 36 hours?  It's up to 16,658,802 of 16.658,802 and stil racing upward.

Something wrong here?

There's an issue scanning Time Machine volumes due to the way the links are managed for incremental backups.  Try disabling scan of that drive, your results should be better.

Thanks so much for your feedback.  It's still going...

Any hints on how I can disable the scan of that drive?  It seems like my only options are "pause" or "cancel"

For the current scan, just cancel.  When you do another System scan, just don't choose the Time Machine volume from the list that is presented (if you have no external drives, just select your main hard disk).

Again, thanks so much!
