I don’t think I can tell you how to get Juniper Networks web blocking software off your computer… simply because I don’t believe it’s on your computer.

What is web blocking software?
If you do a quick search for this, you’ll find that Juniper Networks produces web filtering software that’s targeted at corporate environments.
Your employer probably uses as part of providing the internet connection if you’re connecting through work. As you said, it’s targeted at corporations who want to prevent employees from going places where they shouldn’t be while using company equipment.
If you’re connecting from home, then it looks like something your ISP does – which I’ll admit is unusual.
Web filtering: Employer vs ISP
Whether or not you agree with your employer using this is irrelevant. When you’re using a service provided by your employer, they set the rules, and those rules can be as arbitrary and capricious as they like.
If your ISP implemented it, however, you might want to talk to them, if only to get clarity on exactly why, and what their rules are. Once again, your ISP can also set whatever rules it likes. In the case of a an ISP, though, arbitrary and capricious rules are bad for business, so most don’t do this often.
Because this isn’t on your machine, it’s very unlikely that you’re going to remove or change how it operates.
How do you know if it’s your ISP?
Since you have a laptop, test your connection in another location. Go to an internet café with Wi-Fi and see if you can access those sites there. If you can, then the filtering is happening on your provider’s side and not on your computer.
What happens if you see that message in other places?
If, somehow, it is on your laptop try using Control Panel to uninstall it first. If it’s not there, use Revo Uninstaller. If that still doesn’t work, treat it as malware and read my article, “How do I remove malware?”
The only other thing that I can think of is to use a hotspot VPN-type product, like TOR (The Onion Router). If you can get to those services, they will tunnel your access through whatever this device is and allow you to access whatever you want at the cost of some speed.
Unfortunately because this is exactly what web filtering is used for, my guess is these are exactly the kinds of things that would also be blocked.
