3. Enter Safe Mode

To effectively remove virus from PC, it’s often best to work in Safe Mode. Safe Mode is a diagnostic startup mode for Windows and macOS that starts your computer with only the essential programs and services running. This prevents many types of malware from loading automatically, making them easier to locate and remove.

Why Use Safe Mode for Malware Removal?

• Disables Malware: Many malicious programs are designed to launch automatically when your operating system starts. In Safe Mode, these auto-start functions are often bypassed.
• Reduces Interference: With fewer programs running, your legitimate antivirus and anti-malware tools can perform more effectively without competition from the malware itself.
• System Stability: If malware has severely compromised your system, Safe Mode might be the only way to get your computer to boot up and function reliably enough to run scanning tools.

How to Enter Safe Mode:

• Windows 10/11:
  1. Restart your PC.
  2. As it starts up, typically you’ll hold down the Shift key and click “Restart” from the Power options on the login screen or Start Menu.
  3. Choose “Troubleshoot” > “Advanced options” > “Startup Settings” > “Restart.”
  4. After the PC restarts, you’ll see a list of options. Select “4” or “F4” to start in Safe Mode, or “5” or “F5” for Safe Mode with Networking (though avoid networking if possible for initial steps).
• macOS:
  1. Restart your Mac.
  2. Immediately after your Mac starts, press and hold the Shift key.
  3. Release the Shift key when you see the login window.

Once in Safe Mode, your screen resolution might be lower, and some features might be unavailable. This is normal. You’re now ready for the actual malware cleaning guide operations.

4. Run Comprehensive Malware Scans

With your device isolated and in Safe Mode, it’s time to unleash your security software. This is a crucial malware removal step where you actively seek out and eradicate the threats. You’ll need reliable anti-malware and antivirus tools for effective threat removal.

Steps for Running Scans:

1. Update Your Security Software (if possible): If you’ve managed to get into Safe Mode with Networking and your internet connection is stable and considered safe (e.g., you’re sure the malware isn’t using it), update your antivirus and anti-malware software. Newer definitions mean better detection. If not, proceed with existing definitions.
2. Use Your Primary Antivirus: Open your installed antivirus software (e.g., Windows Defender, Avast, Norton, McAfee) and initiate a full system scan. A quick scan might miss deeply embedded malware.
3. Employ a Second Opinion Scanner: No single antivirus is 100% effective. It’s highly recommended to use a reputable second-opinion anti-malware scanner. Popular choices include Malwarebytes, SpyBot Search & Destroy, or HitmanPro. Install one (if you don’t have it already) and run a full scan.
   • Self-healing tip: If your malware is preventing you from downloading or installing new security software, try downloading them on a clean, separate device (e.g., a friend’s computer, a USB drive) and transferring them via USB.
4. Review and Quarantine/Remove: Once the scans are complete, the software will typically present a list of detected threats. Carefully review this list. In most cases, you should choose to “Quarantine” or “Remove” all detected malicious items. Avoid deleting files directly unless you are absolutely certain they are malware and not critical system files.

This process can take several hours depending on the size of your hard drive and the number of files. Be patient and let the software do its job. For insights into powerful security tools, you might find articles on AI Threat Detection Tools That Actually Work helpful for future malware detection.

5. Update All Software and Operating System

After successfully running scans and removing detected threats, it’s time to address potential vulnerabilities that allowed the malware to infect your system in the first place. This malware prevention step is critical for robust cybersecurity protection.

Why Updates are Crucial:

• Patch Vulnerabilities: Software developers regularly release updates that fix security flaws (vulnerabilities) that hackers exploit to deliver malware. Outdated software is a common entry point for attacks.
• Enhanced Security Features: Updates often include improvements to existing security features or introduce new ones, bolstering your overall defense.
• Compatibility and Performance: While not directly security-related, updates also improve software compatibility and performance, ensuring a smoother user experience.

What to Update:

• Operating System (OS): Windows Update for Windows PCs, and System Settings/App Store for macOS. Ensure all pending updates are installed.
• Web Browsers: Chrome, Firefox, Edge, Safari – make sure they are running the latest versions. Most browsers update automatically, but it’s good to check manually.
• Antivirus/Anti-Malware Software: Ensure your security software is always up-to-date with the latest threat definitions.

   • Go to “Control Panel” > “Programs” > “Programs and Features” (or “Settings” > “Apps” > “Apps & features” in Windows 10/11).
   • Review the list of installed programs. Look for anything you don’t recognize, didn’t intentionally install, or looks suspicious (e.g., generic names, programs installed around the time of the infection).
   • If you find suspicious programs, select them and click “Uninstall.” If unsure about a program, search its name online to determine if it’s legitimate or malware.
2. Check Startup Programs:
   • In Windows, open Task Manager (Ctrl+Shift+Esc), go to the “Startup” tab.
   • Disable any unknown or suspicious entries that are set to launch with Windows. This won’t uninstall them but will prevent them from running immediately.
3. Review Browser Extensions (All Browsers):
   • Chrome: Type chrome://extensions in the address bar.
   • Firefox: Type about:addons in the address bar, then go to “Extensions.”
   • Edge: Click the three dots menu (…) > “Extensions.”
   • Look for any extensions you don’t remember installing, are unfamiliar, or seem to be causing issues (like excessive ads or redirects). Remove or disable them.
   • Consider resetting your browser settings to default if problems persist.
4. Clear Browser Cache and Cookies: This can remove any lingering malicious scripts or tracking cookies.

This meticulous review ensures that no remnants of the infection or related unwanted software continue to compromise your device security basics.

• Account Security: Changing passwords immediately limits the damage if your accounts were accessed.
• Prevent Re-infection: If your old passwords were weak or reused, they could be a vector for future attacks.

Which Passwords to Change First:

• Email Accounts: Your primary email is often the gateway to many other accounts (password resets, verification codes). Secure this first.
• Banking and Financial Services: Online banking, investment accounts, payment services (PayPal, Venmo).
• Social Media: Facebook, X (formerly Twitter), Instagram, LinkedIn.
• Online Shopping: Amazon, eBay, and other e-commerce sites.
• Work-Related Accounts: If your infected device was used for work, inform your IT department immediately and change all work-related passwords.

Best Practices for New Passwords:

• Strong and Unique: Use a combination of uppercase and lowercase letters, numbers, and symbols. Aim for at least 12-16 characters.
• Avoid Reusing: Never use the same password for multiple accounts.
• Use a Password Manager: Consider using a reputable password manager (e.g., LastPass, 1Password, Bitwarden) to generate and store strong, unique passwords securely.
• Enable Multi-Factor Authentication (MFA): Wherever available, enable MFA. This adds an extra layer of security, requiring a second verification method (like a code from your phone) even if your password is stolen.
