Boss Prefer Norton Anti-virus Software

I have installed few different anti-virus software in my office PC to test on which anti-virus is provides better performance for the last 2 years. So far, I think my boss prefer Norton anti-virus the most. She has more confidence on using these products. I am not sure how the performance is actually, but if my boss does not mind to pay for the annual subscriptions fees then I do not mind to use it for my computer too.
