I just got a new windows 10 computer, and wanted to make sure I updated all the drivers, so I got some freeware that would do it all for me.  It had good reviews on Cnet, so I went ahead and downloaded it. 

I ran Malwarebytes, and it identified this program as a PUP. I quaranteened all the alerts.  I then did the scan again and it found a couple more.  At this point I just decided to reset windows, getting rid of all my apps and files.

The reset gives you the option to also format the harddrive, but I wasn't sure what this would do-- if it would get rid of windows on the MACHINE altogether, or if I'd lose any software that CAME with the computer.

So I elected to not format the drive.  I reinstalled windows after the reset, installed AVAST and Malwarebytes, and they found no issues (except Avast did find a network issue, strangely, but didn't tell me what it was; just said it was now resolved). 

What should I do? Is it worth formatting the drive for a PUP issue? If I do, will I be able to get Windows 10 Pro back?Pup's are relatively harmless...THINK of cookies on STEROIDS...PUP = Potentially Unwanted Program. They are programs that are sometimes installed by other programs without user consent, and are typically (not always) of questionable quality or integrity.
