Welcome @bradley

You will need to Reset to Defaults, for all installed browsers.

Safari -
Chrome - Reset Chrome browser settings - Chrome Help
Firefox - Reset Firefox preferences to troubleshoot and fix problems | Firefox Help

You may lose unsaved bookmarks, passwords etc.

Remove "Ads by VNPApps" virus (Easy Removal Guide)

That might help but Mac is more transparent in my opinion- all you need to do is to go to Finder (that smiley face) then Applications to find the sucker!

Then reset to defaults. @Huracan got them all except for Safari, where you do this (thanks to dominic23 from Apple Support Forums! see it here how to reset safari 8 | Apple Support Communities)

Force Quit .



Press command + option + esc keys together at the same time. Wait.

When Force Quit window appears, select the Safari if not already.

Press Force Quit button at the bottom of the window. Wait.

Safari will quit.



Relaunch Safari holding the shift key down.





Turn off Wifi. Click Wifi icon in the menu bar and select “Turn Wifi off”.

Visit another website.

You won’t have internet connection.

Turn on Wifi. Click Wifi icon in the menu bar and select “Turn Wifi on”.

Select your Network.
