My Macbook Pro has been infected with something and Webroot won't scan. Ideas?

I'm getting popups, and some things aren't opening because they say a popup blocker has blocked them. If I turn off the popup blocker temporarily, they still don't open.
 
Meanwhile, Webroot says the last scan was interrupted and it won't scan again.

Hello andymead,
 
Welcome to the Community!,
 
Would you please reboot your Macbook Pro and then see if Webroot will scan your system? Let me know if Webroot isn't scanning.
 
Also we need to check your System Preferences. and I'll show you how when you can tell me Webroot is still working.
 
Awaiting your reply!
 
Thanks,
 
 

Hello andymead,
 
I'm going ahead and give you more information concerning your protection of your Macbook Pro. If you want to check these perferences then please look at this overly long reply.
 
You may need to Check your Disc Permmisions Shown beloiw. Open up Launchpad/Other/Disk Utility/
 

 
 
 
Please check you System Preferences as shown below. Open Security & Privacy.
 

Then make sure there is a check mark in Mac App Sore and Identified Developers.
 

 
 
I would suggest that you issue a Support Ticket if you cannot understand this information below.
 

Examine Browser Extensions

Examining browser extensions or add-ons are often sufficient to diagnose the issue. Look at the extensions you have installed in your browser, using the following methods:

• Safari – choose Preferences from the Safari menu, then click the Extensions icon, near the right side of the row of icons along the top of the window.
• Chrome – choose Preferences from the Chrome menu, then click the Extensions item in the list on the left side of the window.
• Firefox – choose Add-ons from the Tools menu, then look at both the Extensions and Plugins lists in the window that opens.

It’s important to understand that there are plenty of legitimate browser extensions out there. If you see any of the items shown in bold below, however, that’s a sign that you have adware installed.
