Malware remains one of the biggest threats to Windows users, from home PCs to business networks. Many infections happen not because of advanced hacking, but because of overlooked security basics or common mistakes. Whether you’re a beginner looking for guidance or an experienced user wanting to tighten your defenses, the tips below will help you keep your Windows system secure.
Why Do Windows Users Get Infected? Common Mistakes
Before diving into strategies, it’s important to recognize how infections happen. Most are due to:
– Neglecting to update Windows and software
– Downloading from untrusted sources
– Clicking suspicious links or attachments
– Using weak or reused passwords
– Disabling security features for convenience
This article covers 15 actionable tips, highlighting frequent errors and how to avoid them, with guidance tailored for both beginners and advanced users.
1. Always Keep Windows and Software Updated
Mistake to avoid: Ignoring update notifications or postponing them indefinitely.
Updates often contain security patches for newly discovered vulnerabilities. Delaying these exposes your PC to known attacks.
How-to:
– Go to Settings > Update & Security > Windows Update
– Click Check for updates
– Enable automatic updates for both Windows and other Microsoft products
2. Use a Trusted Antivirus and Keep It Active
Mistake to avoid: Relying only on Windows Defender without additional protection or disabling your antivirus for performance reasons.
Windows Defender is solid, but a layered defense is stronger. Many infections occur after users disable antivirus temporarily and forget to reactivate it.
Tip: Choose a reputable antivirus and schedule regular scans.
3. Beware of Phishing Emails and Suspicious Links
Mistake to avoid: Clicking on links or opening attachments from unknown or unexpected sources.
Even advanced users fall for well-crafted phishing attempts. Always inspect the sender’s address and hover over links to preview URLs before clicking.
4. Download Only from Official or Trusted Sources
Mistake to avoid: Installing software from random websites, torrent sites, or links received through messages.
Unverified downloads can contain hidden malware.
How-to:
– Use the official website or Microsoft Store for all downloads.
– For drivers, visit the manufacturer’s official support page.
5. Use Strong, Unique Passwords with a Password Manager
Mistake to avoid: Using “123456” or the same password for multiple sites.
Password reuse is a major vulnerability. Use a password manager to generate and remember strong, unique passwords for each account.
6. Enable Firewall Protection
Mistake to avoid: Disabling the firewall to troubleshoot connectivity issues and forgetting to turn it back on.
Windows Firewall blocks unauthorized access.
How-to:
– Go to Control Panel > System and Security > Windows Defender Firewall
– Ensure the firewall is ON for both private and public networks
7. Limit Administrator Privileges
Mistake to avoid: Running your main account with Administrator rights.
Malware can do more damage if it gains admin-level access.
How-to:
– Use a standard user account for daily tasks
– Only use the admin account for system changes
8. Turn Off Autorun for External Devices
Mistake to avoid: Allowing USB drives or external media to run files automatically.
Some malware spreads via USB by taking advantage of autorun.
How-to:
– Open Control Panel > AutoPlay
– Uncheck “Use AutoPlay for all media and devices”
9. Regularly Back Up Your Data
Mistake to avoid: Not backing up files, leaving you vulnerable to ransomware.
Maintain backups on external drives or secure cloud services. If malware strikes, you can restore your system without paying ransoms.
10. Use Glary Utilities for Regular System Cleanup
Mistake to avoid: Ignoring accumulated junk, outdated registry entries, or leftover files that can harbor malware remnants.
Glary Utilities offers comprehensive system maintenance, including:
– One-click cleanup of junk files and privacy traces
– Registry repair to eliminate invalid entries
– Startup manager to control apps that launch with Windows
– Malware removal tools for detecting and cleaning infections
How-to for Beginners:
– Download and install Glary Utilities from the official website
– Open the program, select “1-Click Maintenance” and run a scan
– Follow the prompts to clean up found issues
Advanced Users:
– Use the built-in process manager to analyze running tasks
– Schedule automatic cleanups and updates
– Utilize the file shredder to securely delete sensitive files
11. Don’t Disable User Account Control (UAC)
Mistake to avoid: Turning off UAC for convenience when installing software.
UAC warns you when a program tries to make system changes. Leave it enabled for an extra layer of defense.
12. Be Cautious with Remote Desktop and Network Services
Mistake to avoid: Leaving Remote Desktop enabled and poorly configured, allowing attackers to access your PC remotely.
How-to:
– Disable Remote Desktop if not needed
– If required, use strong passwords and network-level authentication
– Restrict access to specific trusted IP addresses
13. Avoid Pirated Software and Cracks
Mistake to avoid: Installing pirated software, which often contains hidden malware or unwanted programs.
Using legitimate software ensures you receive updates and support, reducing your risk of infection.
14. Monitor System Behavior for Unusual Activity
Mistake to avoid: Ignoring slow performance, unexpected pop-ups, or unknown programs.
Use Glary Utilities’ startup manager and process monitor to review what runs on your PC. Unfamiliar entries can be researched or removed.
15. Educate Everyone Who Uses Your PC
Mistake to avoid: Assuming all users understand safe computing practices.
If others share your computer, teach them these basics. Set up separate user accounts with limited privileges for children or guests.
Summary for Beginners
– Keep Windows and all software updated
– Use strong, unique passwords with a manager
– Only download from official sources
– Run regular system cleanups with Glary Utilities
– Never click suspicious links or open unknown attachments
– Enable firewall and antivirus at all times
Summary for Advanced Users
– Use restricted user accounts for daily operations
– Monitor system processes and startup items with Glary Utilities
– Regularly back up and test your restore process
– Configure network services securely and audit your system for vulnerabilities
– Stay informed about new Windows threats and best practices
