10 Signs Your Computer Has Been Hacked (And What To Do)
Cybercriminals are getting smarter every year—and you don't have to be a large corporation to become a target. Home users and small businesses in Ball Ground, GA and across North Georgia are increasingly in the crosshairs. Knowing the warning signs of a hack can save you thousands of dollars and enormous stress.
1. Your Computer Is Running Unusually Slow
If your once-fast PC has suddenly become sluggish, malware running in the background could be consuming your processor and RAM. While slowdowns can have innocent causes, a sudden unexplained change in speed is a red flag.
2. Unfamiliar Programs Have Appeared
Check your installed programs list. If you see software you never installed—especially tools with generic names or random letter combinations—you almost certainly have a problem.
3. Your Passwords No Longer Work
If you find yourself locked out of email, social media, or banking accounts, a hacker may have changed your credentials after gaining access. This is a serious, time-sensitive emergency.
4. Friends Are Receiving Spam From You
When people in your contacts report getting suspicious emails or messages from you, your email account or social media profile has likely been compromised and is being used to spread phishing links.
5. Your Webcam or Microphone Activates Unexpectedly
Indicator lights that switch on when you're not using the camera or microphone are a telltale sign of spyware. Some advanced malware can disable the indicator light entirely, so regular security scans are critical.
6. You Notice Unusual Network Activity
Use your router's admin panel to watch outbound traffic. Data leaving your machine at odd hours—especially to foreign IP addresses—suggests something is phoning home with your information.
7. Your Browser Has New Toolbars or Redirects
Browser hijackers install toolbars, change your homepage, and redirect your searches to ad-laden sites. They're often bundled with free software downloads.
8. Antivirus Has Been Disabled
Sophisticated malware often disables security software as a first step. If Windows Defender or your antivirus won't start and you didn't turn it off, treat it as a confirmed compromise.
9. Ransomware Notice on Screen
A locked screen demanding Bitcoin or gift cards is ransomware—one of the most damaging cyber threats today. Do not pay. Disconnect from the internet immediately and call a professional.
10. Files Are Missing or Encrypted
Unexplained file deletions or files with strange extensions you can't open are ransomware symptoms.
What To Do Immediately
- Disconnect from the internet to stop data from leaving your machine.
- Change all passwords from a known-clean device.
- Run a full malware scan with a reputable tool like Malwarebytes.
- Enable two-factor authentication on all important accounts.
- Call a trusted IT professional—many issues require expert remediation to fully remove.
