I would say you are in no way in the clear, and no you should not have hit 'accept' in a scenario where you were locked out of your files and some random message came up saying 'accept me', purporting to be from 'Webroot' ... to regain access to them.

Unless you KNOW that you actually installed Webroot (or it came with your PC) this is for sure a worrisome situation afa viruses go.

Other malicious apps can mimic the appearance of known security apps like Webroot in a convincing way, so unless you know your PC has a legit copy of Webroot protecting it ... I'd be concerned.
