That sinking feeling when your computer or account feels compromised? It’s terrifying, and knowing what to do next can be hard.

It’s a scary situation, but don’t panic. Many people go through this. Acting fast and correctly is what truly matters.

We will help you figure out if you’ve been hacked, what immediate steps to take, and when it’s best to call in expert help.

First, Confirm the Hack: Are You Really Compromised?

The feeling that you’ve been hacked is terrifying, but sometimes a computer glitch can feel just as scary. Before you take drastic action, it helps to confirm if you’re truly compromised.

Common Signs You Might Have Been Hacked

Look for these clues. They often tell you that someone has accessed your computer or online accounts:

  • Strange emails or social media posts: If your friends or followers report odd messages coming from your account.
  • Login or password change alerts: Notifications about someone trying to log in, or your password being changed, when you didn’t do it.
  • Missing or encrypted files: If your files disappear or you cannot open them, this could be ransomware.
  • Your computer acts strangely: Unexpected pop-ups, a very slow internet connection when it was fast before, or new toolbars appearing in your browser.
  • Unusual bank activity: Charges or transactions on your bank account that you do not recognise.

Rule Out a Simple Glitch

Sometimes, a slow computer is just a slow computer.

  • Is the problem happening across all your apps, or only in one specific programme?
  • Have you recently installed new software or updated Windows?

These could be signs of a simple software conflict, not necessarily a hack. But if you see multiple signs, especially those involving your personal accounts, it’s safer to assume the worst.

Immediate Steps: Act Fast, Act Safely

If you think you have been hacked, every second counts. Acting quickly and correctly can limit the damage.

Disconnect Your Computer From the Internet

This is the very first thing you must do.

  • For Wi-Fi: Click the Wi-Fi icon in your taskbar and turn Wi-Fi off.
  • For wired internet (Ethernet): Unplug the internet cable directly from the back of your computer.

 

Why this helps: Cutting the internet stops any attacker from further accessing your computer. It also prevents any malware from spreading to other devices on your home network or sending your personal data out.

Change Your Important Passwords (Use Another Device!)

Once you are offline, your next urgent task is to change all your important passwords.

  • Change everything vital: Start with your main email account, then banking, social media, and any shopping sites.
  • Use a different device: Do not use the computer you suspect is hacked. Use a completely different, clean device, like your phone. Ideally, disconnect your phone from your home Wi-Fi and use mobile data, in case your router is also compromised.

This is a key step in regaining control. And for future protection, remember to always use strong, unique passwords for every account so you can avoid.

Next Steps for Recovery

Once you have disconnected your computer and changed your crucial passwords, you can take a few more steps towards recovery.

Tell Your Contacts and Your Bank

  • Friends and family: If your email or social media accounts were hacked, tell your contacts. They might receive strange messages from you, and it helps them stay stay safe.
  • Your bank: If you saw any unusual activity in your bank accounts, contact your bank immediately to report it.

Scan for Malware (Use Caution)

Now that your computer is offline, you can run a malware scan.

  • Use the antivirus software already installed on your PC.
  • For a deeper scan, you might consider restarting your computer into Safe Mode (you can usually find instructions for this online by searching for “Windows Safe Mode”). Safe Mode only runs essential programmes, which can help your antivirus find stubborn infections.

Be realistic: A basic scan is a good first step, but if it was a serious hack, or you suspect complex malware, simply scanning your PC yourself might not be enough to completely clean it.

Back Up What You Can (If It Looks Safe)

If your computer appears to be working normally and you don’t suspect your files are encrypted or corrupted by ransomware, you should back up your most important documents.

Copy your crucial photos, videos, and work files to a separate, external hard drive that you know is safe. Do this before any further cleanup or repairs, just in case something goes wrong.
