I think at least some of these computers have something in common - like they are hacked or run by hackers. In particular the IP address 96.10.27.184 is clearly trying to alter the user agent in their request. I am pretty sure some of the others are doing the same. A few of them may be people who just need to update their browsers to the latest version.
Another interesting thing is that most of these visits were referred by Google for whatever that is worth.
