Hi, and thank you for your question. My name is ***** ***** I'll be assisting you today.
It looks like your browser/system was hijacked by a rogue service claiming to be from Microsoft - they show fake popups/alerts to trick the user into paying for their "services" and install their worthless software and/or other junk items in the process.
May I connect with you remotely to troubleshoot the issue now?
Please reply back using the box below, and then we will continue further.
