Is it safe to let someone remote into my PC? How remote IT support really works
Letting a stranger control your computer from afar sounds exactly like the thing you are warned never to do, and sometimes it is. The difference between legitimate remote support and a scam comes down to one thing: who started the contact. Here is how real remote support works, and how to tell it from the con.

How legitimate remote support works
When a real IT person helps you remotely, you stay in control the whole way.
You start it, or you approve it
Support connects only after you have asked for help and you enter or accept a one-time code. Nothing happens without your say-so.
You watch the whole session
Your screen stays on and you see every click and every window they open. Nothing is hidden.
You can end it any time
Close the app, or just pull the internet, and the connection drops on the spot.
A one-time code, not standing access
A legitimate tool gives access for that session only. When it is done, they cannot reconnect without you generating a new code.
A real technician expects you to be cautious and works within it. They will never mind you asking what they are doing.
The scam version
The same kind of software, in the wrong hands, is one of the most common ways people are talked out of their money. The scam almost always looks like one of these.
! An unsolicited phone call
Someone claims to be from Microsoft, Apple, Telstra, the NBN, your bank, or tech support, says your computer is infected or has been hacked, and wants to fix it. Microsoft, Apple and your telco do not cold-call you about viruses. Ever.
! A scary pop-up or full-screen page
Your computer is infected, call this number now, often with an alarm sound and a warning not to restart. It is a web page, not a real virus alert. Don't call the number.
Both funnel you to the same next step: install a remote-access app so they can help. Once they are in, they will pretend to find problems, then either charge you to fix nothing, talk you into logging into your bank while they watch, or accidentally refund too much and pressure you to send the difference back.
If you didn't start the contact, it is a scam. Hang up. Close the pop-up.
The safe rules
Two rules cover almost every case.
1. Only ever let in someone you contacted, on a number you looked up. From the company's official website, your bank card, or a bill. Never a number from a pop-up, a text, an email, or an incoming call.
2. Never someone who called or messaged you first. A real company that genuinely needs to reach you will be fine with you hanging up and calling the official number back. A scammer will pressure you to stay on the line, and that pressure is the tell.
A few more that catch the rest:
If a technician ever asks you to log into your bank, buy gift cards, move money to keep it safe, or install something to get a refund, it is a scam, every time. Stop and hang up.
If you have already let someone in: disconnect the internet, uninstall the remote-access app, run a security scan, change passwords for anything you touched during the session from a different device, and call your bank straight away if you accessed banking or money moved. If the machine needs a proper clean afterwards, the clean-up-a-compromised-PC guide walks through the order.
Report it
If you have been targeted or caught out, these are the places that help, and they are free.
Scamwatch
Scamwatch (scamwatch.gov.au) covers remote-access and tech-support scams and takes reports. It is run by the National Anti-Scam Centre.
ReportCyber
ReportCyber (cyber.gov.au) is the place to report cybercrime, especially if money was lost.

Your bank first
Contact your bank straight away if any money moved, or you logged into banking during the session.
The short version
Real remote support only happens after you ask for it. You watch the whole session, you can end it any time, and it is a one-time code, not standing access. An unsolicited caller, or a your-computer-is-infected pop-up telling you to install remote software, is the scam: hang up, close it, and only ever let in someone you contacted on a number you looked up yourself.
