Website problem

I have a small home based web business and this message has just started appearing - 

symres:C:\Program%20Files\Norton%20Internet%20Security\MUI\18.6.0.29\09\01\coUICtlr.loc/SUSPICIOUSREDIRECT.HTML

 

I am not tech savvy and would like suggestions as to what I can do before this affects my business.

Hello BobH,

If so, please feel free to send me a Private Message with your website address and I'll check it out.
