Let a scammer into your computer, or email hacked? What to do now

Scammers are convincing, and the people who fall for them are not foolish — they are usually being rushed by someone pretending to be from their bank, their internet provider or Microsoft. If it has happened to you, what matters now is acting quickly and in the right order. Most of the damage can be limited.

How these scams usually go

Recognising the pattern helps you know what the scammer may have done, and helps you spot the next attempt.

  • The call or pop-up — someone claims your computer, internet or bank account has a problem — often "from" Telstra, NBN, Microsoft, Apple or your bank
  • Remote access — they ask you to install a program such as AnyDesk or TeamViewer, or visit a site that gives them control of your screen
  • The urgency — they insist it must be fixed now, keep you on the phone, and discourage you from hanging up or asking anyone
  • The ask — logging into online banking "to receive a refund", reading out a code sent by SMS, or buying gift cards

Do these first, in this order

Speed matters most for your money, so start there. Then cut the scammer off from the computer.

  • Call your bank — use the number on your card or the bank's official website, not one the caller gave you — ask them to freeze or watch your accounts
  • Disconnect from the internet — turn off Wi-Fi or unplug the network cable so any remote connection is cut
  • Do not answer their calls — scammers often ring back posing as a "fraud team" or the police — hang up
  • Change passwords from another device — start with email and banking, using a phone or a computer you trust, not the one they accessed

Clean up the computer — Windows and Mac

Remove the remote-access program and anything else they installed. If you are unsure what they did, it is safest to have the machine checked before you use it for banking again.

On Windows

  • Uninstall remote tools — Settings > Apps > Installed apps — remove AnyDesk, TeamViewer, UltraViewer, ScreenConnect or anything you do not recognise
  • Check startup — Task Manager > Startup apps — disable anything unfamiliar
  • Run a full scan — Windows Security > Virus & threat protection > Scan options > Full scan
  • Browser extensions — remove extensions you did not add yourself

On a Mac

  • Remove remote tools — check Applications for AnyDesk, TeamViewer and similar, and drag them to the Bin
  • Screen-control permissions — System Settings > Privacy & Security > Screen Recording and Accessibility — remove apps you do not recognise
  • Login Items — System Settings > General > Login Items — remove anything unfamiliar
  • Profiles — in System Settings, look for a "Profiles" or "Device Management" section; one you did not set up is a red flag

If your email has been hacked

An email account is the key to most of your other accounts, because password resets go there. Once you are back in, check for the changes attackers commonly make to keep access.

  • Change the password and sign out everywhere — most providers have an option to sign out of all other sessions
  • Turn on two-step verification — a code from your phone or an authenticator app stops a stolen password from being enough
  • Check forwarding and rules — attackers often add a rule that forwards or deletes your mail so you do not notice
  • Check recovery details — make sure the recovery phone number and email are still yours
  • Warn your contacts — tell people not to act on recent messages from you asking for money or payment changes

Report it

Reporting helps you and others. In Australia, report scams to Scamwatch (scamwatch.gov.au) and cybercrime, including hacked accounts and losses, through ReportCyber at cyber.gov.au. If your identity documents or details were shared, IDCARE (idcare.org) is a free national identity support service that can walk you through the next steps.

Common questions

A scammer had remote access to my computer — can they still get in?

Usually not once the remote-access program is removed and the computer has been disconnected and restarted. The bigger risk is what they saw or installed while connected, so remove unfamiliar programs, change passwords from another device and, if you are unsure, have the computer checked before using it for banking.

Do I need to wipe my computer after a scam?

Not always. If they only had a short remote session and you have removed the tool and scanned clean, that is often enough. If they were connected for a long time, installed several programs, or you cannot tell what they did, a reset is the safest choice — back up your personal files first.

Will Microsoft, Telstra or my bank ever call about a virus on my computer?

No. Legitimate companies do not cold-call about viruses or ask you to install remote-access software. A pop-up with a phone number telling you to call about an infection is a scam too.

Can I get my money back?

Sometimes, especially if you contact your bank quickly. The sooner the bank knows, the better the chance of stopping or recovering a payment — which is why calling the bank comes first.
