Remote tech help

When your computer misbehaves, remote support can be a lifesaver. A technician connects to your screen over the internet, diagnoses the problem and fixes it while you watch, without anyone visiting your home. Workplaces use remote support every day, and many independent technicians offer it to households and small businesses.

But criminals have learned to exploit the same tools. Scamwatch and the Australian Signals Directorate warn about remote-access scams, in which callers pretending to be from banks, telcos or tech companies talk people into installing screen-sharing software, then steal their money. Knowing how legitimate support works is the best protection against the fake kind.

The golden rule

Legitimate remote support almost always starts with you. You contact your workplace IT team, a technician you've chosen or the support line of a company you deal with, using contact details you found yourself. Scams usually start with them: an unexpected phone call, pop-up or message claiming there's a problem with your computer, internet or bank account.

If someone contacts you unexpectedly and asks you to install software or give them access to your device, hang up or close the message. If you're worried, contact the organisation using details from its official website, a bill or your card.

Staying in control during a session

Even with a trusted provider, stay at your computer and watch what the technician does. Don't share passwords for banking or email, and never log into internet banking during a session. End the session when the work is done, and make sure the remote access software doesn't remain able to connect without your permission.

Prevention beats cure

Many problems that send people looking for help can be prevented. Keeping your operating system, apps and browser updated, using reputable security software, backing up your files and being careful about what you download avoid many common issues. The Australian Signals Directorate's cyber.gov.au has practical guidance for households and small businesses.

If something goes wrong

If you think a scammer has accessed your computer or accounts, act fast. Contact your bank, disconnect from the internet, remove the remote software, scan for malware, change your important passwords from a different device and turn on multi-factor authentication. Report it to Scamwatch, or to ReportCyber if a cybercrime has occurred. IDCARE provides free support if your personal information has been compromised.

Fixing things yourself

Not every problem needs a technician. Restarting, installing updates, freeing up storage, removing unwanted startup programs and running a security scan solve many everyday issues. Our guide to fixing common computer problems explains safe first steps and when to call in help.

For workplaces

If you work for an organisation, follow its IT and security policies. Use the official support channels, report suspicious messages, and never install remote access software at the request of someone you can't verify, even if they say they're from IT.

Choosing between remote and in-person help

Remote support suits software problems: a program that will not install, settings that have gone wrong, email that stopped syncing, a printer driver that needs reinstalling or a slow computer that needs tidying up. It is usually quicker to arrange, because nobody has to travel, and you can watch every step on your own screen. In-person help makes more sense when the hardware itself is the problem. A cracked screen, a laptop that will not power on, a failing hard drive, liquid damage or a noisy fan all need someone to handle the machine. If the computer cannot start or connect to the internet, a remote session is simply not possible.

A sensible approach is to describe the symptoms first and ask the technician which option fits. A reputable provider will tell you honestly when remote help will not work and you need to bring the device in instead.

Questions to ask before anyone connects

Before you let a technician connect, ask a few plain questions. What exactly will they be doing? Which software will they ask you to install, and will it remove itself afterwards? How will they charge, and will they confirm the cost before starting? Will they need your passwords, and if so, can you type them yourself rather than reading them aloud? What happens if the problem cannot be fixed remotely? Clear, unhurried answers are a good sign. Vague replies, pressure to act now or reluctance to explain costs are reasons to stop and find someone else.

Keeping a simple record

Keep a short note of every support session: the date, who helped, what was changed and what you paid. It makes follow-up easier if the problem returns, and it helps you notice anything unusual, such as a charge you do not recognise or software you did not agree to.

Key points

Use remote support only when you started the contact with a provider you trust, stay in control during sessions and end them properly. Hang up on unexpected callers offering to fix your computer. Keep devices updated and backed up, and act quickly if you think you've been scammed.
