Detecting a computer virus can be alarming, but remain calm! Here's a streamlined path to resolution:

1. Disconnect and Diagnose: Immediately disconnect your computer from the internet to prevent further spread. Reboot in Safe Mode, which limits active programs, potentially isolating the virus. Look for unusual applications, pop-ups, or sluggish performance.

2. Scan and Eliminate: Run a thorough virus scan with your installed antivirus software or a trusted online scanner. Follow its prompts to quarantine or delete detected threats. If your antivirus is disabled or ineffective, consider specialized malware removal tools like Malwarebytes or HitmanPro.

3. Clean Up the Aftermath: Delete temporary files (Windows: Disk Cleanup) to remove potential virus hideouts. Change your passwords immediately, especially for crucial accounts like email and banking. Consider backing up vital data to an external drive before proceeding.

4. Fortify your Defenses: Ensure your antivirus software is updated to the latest definitions. Enable real-time protection for continuous monitoring. Practice safe browsing habits: avoid suspicious links, downloads, and emails. Stick to reputable websites and software sources.

5. Seek Help: If the virus persists or you're uncomfortable tackling it yourself, seek professional help from IT experts or dedicated virus removal services. Remember, prevention is key! Regular backups, strong passwords, and vigilant online behavior go a long way in keeping your computer virus-free.
