If you’ve been getting pop-ups for the so-called ‘Yahoo Customer Reward Program’, be wary because it is a scam! Yahoo has never launched such rewards program. The pop-up is part of an adware that will attempt to commandeer your browser search and homepage. It will display numerous pop-ups and deals like this one from Yahoo tricking you to click and participate. Its aim is to gather personal information like your IP address, browsing history, and financial details. 
The adware Yahoo Customer Reward Program is usually installed through bundled software without you knowing. You have to remove it immediately before it infects your computer further or prevents you from changing your settings back.
