Reset Profile in macOS Safari - Remove weknowAC Malware

I came across a really persistent version of weknow.ac malware on a mac. Here's what you need to do to remove it:

• Run Malwarebytes first to remove any crud. CLICK HERE for the Free Version. 
• Then, open the system preferences. 
• Go to "Profiles."
• Click the profile in the list to the left titled "Admin Prefs" and click the minus "-" button at the bottom to remove.
  
• Then open the terminal. 
  
• Enter: sudo profiles -D 
• Enter your password when asked.
• Say "Y" to approve if asked. 
• Restart your Mac.

That should remove the annoying weknowac search page in Safari. If you have the same problem in Chrome, click here for the directions to remove it.
