To effectively get rid of viruses on your computer, follow these steps methodically:
Steps to Remove Viruses
Here's a comprehensive guide to eliminating viruses from your computer:
-
Disconnect from the Internet: Immediately disconnect your computer from the internet to prevent the virus from spreading or sending data. This also prevents further downloads or communication from the virus.
-
Reboot into Safe Mode: Restart your computer in Safe Mode. This mode loads only essential drivers and services, limiting the virus's ability to operate.
- Windows: Usually, you can access Safe Mode by pressing F8 or Shift+F8 repeatedly during startup. Alternatively, in Windows 10/11, you can hold the Shift key while clicking "Restart" from the power menu, then navigate to Troubleshoot > Advanced options > Startup Settings > Restart and select Safe Mode.
- macOS: Restart your Mac and immediately press and hold the Shift key until the Apple logo appears. This boots your Mac into Safe Mode.
-
Delete Temporary Files: Remove temporary files as viruses often hide within them.
- Windows: Use Disk Cleanup (search for "Disk Cleanup" in the Start Menu). Select your drive, and check the box next to "Temporary files." Click "OK" to delete.
- macOS: Empty the Trash. Temporary files are also often cleared during general maintenance, which utilities like CleanMyMac can handle, although manually checking your
~/Library/Caches/and/Library/Caches/folders for suspicious files is also advisable.
-
Run a Virus Scan: Use a reputable antivirus program to scan your entire system. Ensure your antivirus software is up-to-date before scanning. If you don't have one, consider downloading a trial version from a well-known provider like:
- Malwarebytes: Known for its effectiveness in removing malware.
- Norton: A comprehensive security suite.
- McAfee: Another widely used antivirus solution.
- Windows Defender (Windows Security): A built-in option on Windows that has improved significantly over time.
-
Delete or Quarantine the Virus: Based on the scan results, delete or quarantine the detected viruses. Quarantining isolates the virus, preventing it from causing further harm. Your antivirus software will guide you through this process.
-
Reboot Your Computer: After removing or quarantining the virus, restart your computer in normal mode.
-
Change All Your Passwords: Change passwords for all your online accounts, especially email, banking, and social media. The virus may have compromised your credentials.
-
Update Your Software, Browser, and Operating System: Ensure all software, including your web browser and operating system, is up to date. Updates often include security patches that fix vulnerabilities exploited by viruses. Enable automatic updates if possible.
-
Consider a System Restore (Windows): If the virus caused significant damage, consider using System Restore to revert your system to a point before the infection. This option is only available on Windows.
Important Considerations
- Prevention is Key: Install a reputable antivirus program and keep it updated. Be cautious when opening email attachments or clicking on links from unknown sources. Regularly back up your important files.
- Rootkits: If you suspect a rootkit infection, you might need specialized tools or to reinstall your operating system. Rootkits are very deep infections and difficult to remove.
- False Positives: Antivirus software can sometimes identify legitimate files as viruses (false positives). Before deleting a file flagged as a virus, research it online to confirm its status.
