Are These Norton Products?

Good Morning Evening one,

 

I would like to know if the following software is truly part of Norton Products.

 

NRnR.exe

NPE.exe (Norton Power Eraser)

 

I was regularly getting error messages from my copy of Norton Internet Security so I followed instructions supposedly on Norton site to download the above two products to solve my problem.

 

I have since had another error crop up once but by enlarge the software seems to load correctly. The problem is ever since running the above software I have had to put up with annoying adverts poping up every time I go to web sites. This happens in Explorer, Firefox and Chrome. I have Firefoxs' option to turn off pop ups is on but that does not make any difference. I have run a full norton scan of my computer but that makes no difference.

 

Do you have any comments/suggestions.

 

I am using Windows 7.

 

Regards

Terry Cummings
