Microsoft calling? Mind the tech support scammer!

Microsoft calling_ Mind the tech support scammer

After a long day, there is nothing like sitting down at your computer with a cup of tea to catch up on the news online. But what would you do if you were faced with a pop-up telling you that your computer has a virus and that ‘Microsoft tech support’ is conveniently letting you know?

The solution seems only a quick call away. The popup even conveniently provides you with a toll-free number.

However, it’s the people who are claiming to help you that are about to load your computer full of junk and charge your credit card for the privilege.

What these scams look like

These tech scams can appear in various ways, usually as a popup on your browser or a call on your home phone number. Here’s what to look out for:

Over the phone

Usually calling from places such as India, these scammers target people with lists of active phone numbers usually acquired through public phone books or data breaches.

The scam is simple. Someone calls pretending to be calling from Microsoft, a partner company or even your ISP. They say that they have been receiving reports of malicious software on your system and ask you to give them remote control access of the machine to remove the malware.

Once given remote access, they use tools within Windows that show errors that occur normally to scare you. The tech support scammers then use that fear to sell you software for a massive markup, costing hundreds of dollars. You have absolutely no way of knowing what has been installed and what kind of private information you may have just given away.

We wrote a more detailed explanation with how these scams work when one of our own employees was targeted by one of these tech support scammers.

Microsoft is aware of these scams and states on their website:

“You will never receive a legitimate call from Microsoft or our partners to charge you for computer fixes.”


Scammers create websites that claim your system is compromised and to call “Microsoft” at the toll-free number provided.

These scammers pay to reach the top of search engine listings. If you Google ‘tech support online’ looking for a way to fix your computer, you may end up at one of these webpages accidentally. Ranking highly in Google search may be enough to convince you they are a legitimate online tech service, especially if you already believed that you may be infected.

BleepingComputer has previously reported on a particular type of this scam that prevents users from even closing their browser without calling the number on their screen to have the message removed. This kind of scam borders on the edge of ransomware as you feel forced to call and inevitably pay to have your system ‘cleaned.’

Consequences for scammers

Previously a collection of US companies was caught for running this kind of scam by using popups to scare users into calling for tech support and pushing them into purchasing services they didn’t need. CSO Australia reports:

“Charges have been filed against Missouri-registered firms Global Access Technical Support, Global sMind, Source Pundit, Helios Digital Media, and an Indian company, Global Ites Private Limited. Defendants include three individuals who own the firms.”
