Lens as desktop cursor

Hello, I have suddenly a lens as the cursor on my screen.  I want it to disappear as soon as possible.  I think I know how this started, 

I was trying to fill in the Ethias.be form when I was suddenly blocked.  But there is more.  I bought the update for Norton months ago 

and was surprised to get it installed without submitting the key.  Now of course I get messages that my trial is expired.  When I want to 

fix it, it says that my protection is up to date but then when I'm logged out I get messages that I'm not protected anymore.  This lens makes it 

harder to work.  Is this lens a virus or is it just a tool that was put on accidentally?

Have a nice day.

Hello. Look for a program labeled PM2 or similar in your listing of features and programs in Control Panel, uninstall it and restart. You can immediately disable this by pressing the Windows Logo key + Esc key. 

Since you have no idea how this was installed please run a system scan using Malwarebytes free version to see if a PUP has been installed. Allow it to remove what it finds and restart.
