Thunderbird and Firefox

I just removed Zonealarm and McAfee and installed NIS 10 and have several issues.

 

I loath applications that insert themselves into other applications without asking permission.  Even worse is when I am not given the option of removing them.  I am referring specifically to the Norton Toolbar and Norton IPS add-ons that were forced into Firefox.  I want them UNINSTALLED!!!!  Not simply enabled or disabled!  Since the Uninstall buttons for both of them are greyed out Symantec leaves me little choice.

 

As much as I disliked McAfee it was competent enough to recognize Thunderbird as my email client and appropriately scan for spam.  Norton, it seems, is still stuck in the Microsoft middle ages and only recognizes outlook email clients.  Does anyone know if Symantec has any plans to include Thunderbird as an email client or perhaps something else I can use for email protection?

 

Does NIS scan for, detect, and remove rootkits?

 

Thanks
