Digital Payday page automatically opens in Safari
I have Safari Version 11.1.2 on a Mac running High Sierra (version 10.13.6). Digital Payday web page automatically opens in Safari. It is not a pop-up window but automatically appears on the tab bar. I have never visited this site. I contacted AppleCare about this issue. The tech told me to do the following in Safari: (1) check extensions (none were there), (2) clear history, (3) delete cookies. Checked the Applications folder. No suspicious apps. Deleted Trash. Restarted Mac. I downloaded Malwarebytes and ran a scan. 8 threats were detected and remediated. I deleted the quarantined files. This morning, Digital Payday was once again open in Safari. I ran Malwarebytes and no threats were detected. Has anyone had this issue? Thx
