If you are getting a pop-up ad (supposedly from Walmart) that you are the day’s chosen winner to answer a survey, then an adware may have infiltrated your computer. This pop-up scam promises a prize of $1000 Walmart gift card when you’re done answering the said survey.
Don’t be tricked into believing this fake so-called survey. It will ask you to provide personal information and pay a certain amount weekly before getting your “prize”.
Moreover, the adware will also attempt to commandeer your browser search and homepage. It will send you to malicious websites to get money from you or infect your computer further. It may also prevent you from changing your settings back. This adware is usually installed through bundled software without you knowing thus you have to remove it immediately.
