We'll never ask you to install a remote tool out of the blue. If someone does, hang up.
Tech support scams start with a pop-up warning, a phone call or an email saying your computer has a virus, your account is hacked or a payment went wrong. The “helper” then asks you to install a remote access app so they can “fix” it. Once they're in, they can steal files, passwords and money.
Microsoft doesn't make unsolicited calls to fix your computer. When we need to connect to your computer, it's because you asked us for help.
