• Research reputable options before purchase or download. Examples include Norton Security, McAfee, or Bitdefender.
• For instance, Norton Security Ultra is known for its multilayered defense system against various malware strains.
• Customize Your Scan:
• Open your chosen security application. Instead of relying solely on automated scans (often labeled “Run Smart Scan”), choose a more customized scan option.
• Many applications offer a “Full Scan” that thoroughly examines every nook and cranny of your system.
• Review and Act on Scan Results:
• Once the scan is complete, review the detailed list of any detected threats.
• Follow the recommended actions, which may include quarantining or removing malicious files.
• Some software even offer post-scan recommendations to further secure your system.

Advantages of Third-Party Scanning:​

• Advanced Detection Capabilities:
  Third-party solutions often incorporate cloud-based threat analysis and machine learning. They can detect even zero-day exploits that traditional signature-based methods might miss.
• Customization and Control:
  Users can often schedule scans, perform quick scans for immediate issues, or deep scans when troubleshooting unusual behavior.
• Additional Features:
  Many commercial antivirus programs come with extra utilities like VPN services, secure browsing, and identity protection features that offer comprehensive online safety.

Summary:​

While Windows Security is a solid default option, supplementing it with a trusted third-party software can provide an extra layer of assurance. This method is particularly valuable if you are responsible for handling sensitive data or simply desire peace of mind through enhanced scanning routines.

Method #3: Uninstalling Suspicious Software and Applications​

Sometimes, a noticeable drop in performance or frequent crashes can be traced back to a recently installed app that might be harboring malware. In many cases, simply uninstalling the offending application can resolve the issue. However, it’s wise to run a full malware scan afterward to ensure no remnants remain.

Step-by-Step Guide:​

• Identify the Suspicious App:
• Notice if your PC’s performance begins to decline after installing a new program.
• Use the Windows search function (Windows key + I) to open the Settings app.
• Access Installed Apps:
• Navigate to Settings > “Apps” and then click on “Installed apps.”
• The list of apps is displayed alphabetically by default, but you can use the “Sort” function or the search bar to find a specific app more quickly.
• Uninstall the Problematic Application:
• Click the three dots icon next to the app you suspect is problematic.
• Select “Uninstall” and follow the on-screen prompts.
• Restart your computer once the uninstallation is complete.
• Run a Malware Scan:
• As a best practice, after uninstalling a suspicious application, run a comprehensive scan using either Windows Security or your preferred third-party software.
• This ensures that any remnants of malware that might have spread from the app are detected and removed.

When to Consider This Method:​

• Performance Issues:
  If your PC slows down dramatically or crashes frequently after installing new software, it’s worth investigating whether the application is malicious.
