The OP was asking about Symantec Antivirus, NOT Norton AV:
I used to run Symantec AV when I worked for a corporation that made it available free to employees. A corporate security suite is geared more toward protecting the business versus protecting just one individual. A personal security software or suite, such as Norton AV (from Symantec) is more user friendly and designed for only protecting one user's systems. Corporate security suites will have features to help the IT department push new definitions to employees, lock out features that employees should not mess with and so on.
If you want a review of corporate security software, you will need to look toward the "trade" mags or their websites. This is not my area of expertise, so I don't know the reputable names. Publications such as c|net are primarily geared toward the individual with a smattering of industry news thrown in.
