Understanding the Threat

A virus can do more than just slow down your computer—it can delete files, encrypt them for ransom, or even use your system for malicious activities. The first step in recovery is understanding what you’re dealing with. Viruses come in many forms, from malware that sneaks in through a download to phishing attempts that trick you into giving up personal information.

Immediate Steps to Take

  1. Disconnect from the Internet: This prevents the virus from transmitting data or downloading additional malware.
  2. Enter Safe Mode: Restart your computer and enter Safe Mode. This limits what can run on your computer, helping to prevent the virus from causing further damage.
  3. Run a Virus Scan: Use your antivirus software to run a thorough scan. If you don’t have one, now is the time to get it. There are several reputable free and paid options out there.

Recovering Your Files

  • Check Your Backups: If you’ve been backing up your files, you may be able to restore them from there.
  • Use File Recovery Software: There are tools available that can help recover files deleted by a virus. However, success can vary depending on the virus and how long it’s been since the files were deleted.
  • Consider Professional Help: If the data is particularly valuable and recovery attempts have failed, it might be worth consulting with a data recovery service.

Preventing Future Infections

  • Keep Software Updated: Regularly update your operating system, browser, antivirus, and other software to protect against vulnerabilities.
  • Be Wary of Downloads: Only download files and software from trusted sources.
  • Educate Yourself: Learn about common phishing techniques and malware. Being able to recognize a threat is half the battle.

Summary of Facts

  • Disconnect from the internet and enter Safe Mode immediately after discovering a virus.
  • Use antivirus software to scan and remove the virus.
  • Recover files from backups or use file recovery software.
  • Update software regularly and download only from trusted sources to prevent future infections.
