Yesterday I upgraded my Intel IMac to Snow Leopard.  Now I regularly get notices that something has been blocked by Norton Firewall.  Then it asks for my password to permit SYMUIAgent to make changes.  Should I grant permission?  I don't know what SYMUIAgent is, and I've used Norton Firewall for some time. Previously, notice of their blocking something was inobtrusive and in the lower left corner of my screen.  Now it's right in the middle of everything so that I have to respond to it.


Thanks for any help/info you can give me.

iMac, Mac OS X (10.6.7)

    I just started getting this as I changed to Lion. Please let me know what you did.

    Sorry for the delay.  I just returned from vacation.

    I finally granted permission for SYMUIAgent to make changes.  After I did that once, the annoyance stopped.  I still get occasional messages that someone is trying to penetrate the firewall and asking if I want to permit it.  I always say "No."  I think everything is OK.

    Exact same problem after upgrading to Lion. Please advise?

    The solution is to remove Norton from your system. I hate to be that blunt however it simply is unnecessary on your system. OS X has more than enough security built into it and using ancillary security products tend create more problems than they solve. Follow Norton's uninstall instructions and your system should return to normal.
