The BIG RED FLAG here is that you got a popup for it! If they have to advertise it with a popup, it's probably not worth having, not legitimate, or not safe. My Google search showed a Firefox Add-on called Webshield from TotalAV which is a questionable product on it's own.
Behind every good computer... is a jumble of wires 'n stuff.
Rated 1 out of 5 by Sandy Richards, 12 hours ago Having issues with the "real-time protection" when opening the icon. Get an error message and to reboot but after 3 days of doing this, nothing changes. Hopefully they have a money-back policy! Rated 1 out of 5

I removed the Total Webshield extension. Immediately after removing the Total Webshield extension, I was able to log onto online banking for Bank of America and also Capital One with absolutely no issues. Something is wrong with Total Webshield. Michael Allen
I recommend the built-in Windows Security and if you're not comfortable with just that, add a subscription to Malwarebytes. I don't recommend any "security suites" such as Norton360 or whatever McAfee is calling their suite these days.

Totally agree. I don't think you can do better. Get the real time version of Malwarebytes. There is also a setting in it, that allows it to integrate with Windows Security.
