Why not scan with Grif's tools here. https://www.cnet.com/forums/discussions/how-to-remove-pup-option-603542/#post-f742c795-5881-433b-a29b-6d758efe5cd3
Also do you use WOT?
I've been using a new Dell Inspiron 3000-15 series laptop for 3 weeks now; it came configured with McAfee LiveSafe and I added SuperAntiSpyware when I got it along with McAfee Site Advisor. I was on a website ordering a fruitcake today; Harry & David.com when I received this loud message saying "YOUR COMPUTER HAS BEEN INFECTED" and I was told to call this number; 1-888-746-3662 which I did not because it seemed like a scam.
I closed the message; I then did a shut down; powered the computer back up and then ran a thorough scan using the McAfee LiveSafe software which came with this computer. After that scan finished I ran a thorough scan with SuperAntiSpyware and both scans came up clean. Is there some other security software that I should add to this new computer and start using? Could there still be a virus on this computer? The computer's OS is Windows 7 Pro which according to Dell can be upgraded to Windows 10.
