Robot voice claiming that I made an error on my taxes and I have to call them back. She can.

I did not actually receive a call from this number, but...  My computer screen went red, said I had a "Google Chrome critical error," and told me to call this number.  I did (on a secure line), and was directed to someone who could "help" me.

Sound suspicious enough for you?  Oh, the phone number was supposed to be Microsoft support.

Tech Support Pop Up scam:

Most popups are generated from an Ad on an unsuspecting website and can be closed by end tasking the Browser, if it won't close by trying to close the tab/window. They can be removed by clearing the Cache and History, then restarting the Browser with an Ad Blocker turned on. If your Browser doesn't have one built-in, you might look to see if it supports a Browser Extension Ad Blocker.

This is a known Tech Support Pop-up scam and many different phone numbers have been used with it.
