Secure Your Computer and Account After a Scam Attempt

Take immediate action to remove potential malware and secure compromised credentials if you interacted with fraudulent support.

Tech support scammers often use alarming error messages or fake activation screens to trick users. Your computer may not be 'hacked' in the traditional sense, but you must still ensure no malicious software was installed during the scam.

Run a Full Antivirus Scan

Open Windows Security or your preferred reputable third-party antivirus software. Navigate to 'Virus & threat protection' and select 'Scan options'. Choose 'Full scan' and click 'Scan now' to detect and remove any malware.

Uninstall Suspicious Software

Press the Windows key, type 'Control Panel', and select 'Programs and Features'. Sort the list by 'Installed On' date to easily spot any unknown remote access tools or fake security software installed on the day of the scam. Right-click and select 'Uninstall'.

Change Your Passwords

Log into your Microsoft account from a secure, unaffected device. Go to the Security dashboard and change your password immediately. Ensure you also enable Multi-Factor Authentication (MFA) to prevent unauthorized access.

Secure Your Computer and Account After a Scam Attempt

Report the Scam: If you paid for fake services, contact your bank or credit card company immediately to dispute the charges and cancel the compromised card.

Solution 2

Frequently Asked Questions

Will Microsoft ever call me directly about an Office installation error?

No. Microsoft does not make unsolicited phone calls to help you install software or fix computer issues. Any incoming call claiming to be Microsoft Support regarding an error on your screen is a scam.

How do I know if my Microsoft Office product key is legitimate?

A legitimate product key will successfully activate on the official setup.office.com website. If you purchased it from an unauthorized third-party seller at an unusually low price, it may be a pirated or invalid key.

What should I do if I allowed the scammer remote access to my computer?

Immediately disconnect your computer from the internet. Use another device to change your important passwords (email, banking, Microsoft account). Once disconnected, run a full offline antivirus scan or consult a trusted local IT professional to ensure all remote access software is completely removed.
