Ok

I am a very demanding computer and internet user and have been using Webroot Anywhere Complete for 10 years with well deserved confidence.
I prefer Webroot over all other internet security bundles, including Kaskersky, Bitdefender, and Norton, because Webroot runs on a completely different algorithm. A kind of smart artificial intelligence. Therefore, Webroot catches all suspicious processes, even if they don't exist in the database. In other words, comparing Webroot to other security software is no different than comparing apples to oranges. Webroot has never let me down in the last 10 years. That's why I can't understand those 1 and 2 star ratings. Personally, I think these people must have done something wrong with settings etc. Webroot always gets my full credit and highest rating.

Webroot makes me feel safe browsing the internet. It is not intrusive, uses very little processor resources, and does its intended job.

so fare so good

I purchased a license for Webroot antivirus and this extension came with the license. So far, so good. It is blocking malicious urls. It works.

I tried to uninstall this add-on manually. I followed the steps that Firefox itself suggested. It keeps popping up and reinstalling itself! DO NOT INSTALL IT!!!

Edit:
So, this is how I solved my issue. After I manually uninstalled it, I restarted my computer. It was gone! Solved!

webroot needs to change its invasive policies, persistent reinstallation, extension removal blocking, no good and easy way of uninstalling. even revo pro could not easily remove. it will not let you remove extensions, if you uninstall normally, it reinstalls by way of extension if you reopen any browser. for those purchasing or preloaded 2 months webroot secureanywhere through best buy, you will be constantly reminded 3 weeks before it expires, and it will haunt you and even its own forums suggestions on ways to remove are not working.
