My website, [url removed, login to view] was hacked and a floating ad was placed onto the website. It appears on every page, even on the admin dashboard page. In addition any emails ending in @[url removed, login to view] do not receive emails anymore and are bouncing them back.
In the attached pic, circled in red is the floating ad that was added to my website without authorization.
Looking for someone with website troubleshooting skills to debug my site and restore my emailing functions.
