AOI

Did you contact them, or did they contact you?

You don't tell me enough.

If they claimed to be representing Microsoft Support:

It is a Scam.

Microsoft will never contact you with cold-calls, popups, etc.

This is the advice given to anyone who has any phone calls, etc. like this about Malware, License Expiry, Refunds, etc..

And your machine does not send out messages to anyone saying that it has problems or is infected with Malware, etc.

We all have errors and warnings in our event viewer, which is another ploy they use to scare you

These so-called "Microsoft" Tech Companies either want to sell you worthless software, or gain Remote Access to your Computer to try and steal your Banking and Credit Card details and to also carry out an Identity Theft on you.

You are the only one who knows if you have given them Remote Access.

If you have given them Remote Access and if you do Internet Banking, contact your Bank, explain it to them and change Passwords.

If you use your Credit Card online, cancel it and get a new one issued to you.

And the only way that you willl know that you are free of them is to save your Data and do a clean install of your Operating System.

And Microsoft does not contact you, unless YOU have made prior arrangements with them to do so.

There is a section in the link I am supplying you about this at the end of it
