Browser user agent resource

Question

I have a client who says he is using ie7 from two different sites however our iis logs are showing two different user agents one beginning

Mozilla/5.0+

the other

Mozilla/4.0+

This change occurred on Tuesday.

Does anyone know of a good resource for browsers and the various user agents they pump out?

Does anyone know the difference between the two user agents above?

Thanks in advance, Patrick
