I received a call from someone who claimed that my computer had been identified by Microsoft as vulnerable. I thought it sounded fake, and I told them that I had no way to know if they were who they said they were. Then they said they could prove that they were from Microsoft by giving me my serial number if I would go to a website called www.ammyy.com.

Is this call a scam?

Yes. This is a scam. This is not a legitimate call from Microsoft. Neither Microsoft nor our partners make unsolicited phone calls (also known as cold calls) about your computer security or software fixes.

If you receive a call like this one, it’s a scam, and all you need to do is hang up.

Cybercriminals often use publicly available phone directories, so they might know your name and other personal information when they call you. They might even guess what operating system you’re using. It’s still a scam.

Don’t let scammers encourage you to install dangerous software

Once cybercriminals gain your trust, they might ask for your user name and password or ask you to go to a legitimate website (such as www.ammyy.com) to install software that will let them access your computer to fix it. Once you do this, your computer and your personal information are vulnerable.

Do not trust unsolicited calls. Do not provide any personal information.

Although law enforcement can trace phone numbers, perpetrators often use pay phones, disposable cellular phones, or stolen cellular phone numbers. It’s better to avoid being conned rather than try to repair the damage afterwards.
