Similar to how a car shows signs of malfunction or our bodies exhibit symptoms when we’re ill, computers also display indicators when infected by malware. Common signs include:

  • Unexpected Actions: If your computer starts to shut down, restart, or perform tasks without your input, it could be infected.
  • Changed Home Page: Unauthorized changes to your browser’s homepage can indicate a malware infection.

Action Steps for Suspected Malware

  1. Start Your PC in Safe Mode: Restart your computer and enter Safe Mode. This mode loads only the essential system programs, which can help in diagnosing and fixing the problem.
  2. Scan with Antivirus Software:
    • Use a trusted antivirus program to perform a full system scan. Here’s how:
      1. Open Antivirus.
      2. Select the ‘Protection’ option and then ‘Virus Scans’.
      3. Click ‘Run Smart Scan’.
      4. Allow the scan to complete.
  3. Eliminate the Threat: If malware is detected, follow the antivirus software’s recommendations to quarantine or delete the infected files. Be cautious not to delete critical system files.

    Tip: If you’re unsure about removing a file, consult a tech professional or rely on the antivirus software’s advice to avoid damaging your system.

Additional Tips and Best Practices

Malicious software, or malware for short, can cause a variety of problems for your computer. The good news is that by understanding the warning signs and taking some proactive steps, you can significantly reduce the risk of infection.
