Hi there, ZGrant.

It seems that you've encountered a customer support scam. Most of the time, they'll convince you that there’s a problem with your company file, then offer you a fix. To help you avoid fake customer support scams, I recommend reading our online security tips.

You may also coordinate with your local IT support. They can advise you what antivirus software to use so you can prevent unwanted pop-ups or any malicious adware.

I'm also additional this article to learn how to determine phishing, spam, spoof, or hoax emails: Identify suspicious activity, phishing scams, and potential fraud.

If you have any other concerns or questions, don't hesitate to add a reply below. I'll be around to help.
