This morning when we turned on our laptop a popup that looks like it could be from Norton saying it detected Adware.Webwise on our computer. My husband recently had something similar pop up on his work laptop that was fake, so we were a bit suspicious. I ran a full system scan and it said there were no threats detected. The same thing happened when I ran Norton Eraser. So my question is, is this a real threat or an attempt by some malicious software?
Here's the popup as it appears on my desktop:
Thanks for your help.
