Unwanted explorer problem

A couple of days ago explorer stated every 5 or 10 minutes.  It must be some sort of malware I really do not know. When I log on to my computer a black box appers with a a task command and then explorer runs on a regular basis with a ww1 online fix .co address.  I want to get rid of this unneeded activity. can anyone help.

Had you allowed anyone to remote access into your computer recently, supposedly trying to fix some problem? If so, that was a scam and they may have left some malware behind that is causing this.

Have you run a full system scan with Norton in Windows Safe mode?

I would suggest a second opinion scan using the FREE version of Malwarebytes. You can find it here http://www.malwarebytes.org/products/malwarebytes_free/

Be sure you do not accept the offer of the free trial of the Premium version.
