PC Security: Free Protection for Your Computer

Protecting Your Home Computer: A Security Guide

I frequently receive inquiries regarding PC security. Consequently, I've decided to share my perspective on various methods for safeguarding your computer against viruses, spyware, and other threats.

Initially, I generally don't advocate for paid security suites, with one exception: if a less tech-savvy individual, such as a grandparent, is the primary user. Those unfamiliar with technology may benefit from the simplicity of solutions like Norton or Trend Micro.

Configure these suites for automatic updates and daily scans. This "set it and forget it" approach can minimize the need for frequent technical assistance.

Configuration for Experienced Users

For users with greater technical proficiency, let's explore alternative configuration options. This isn't intended as a definitive "best of" list, but rather a compilation of tools I've found consistently effective.

• Anti-Virus: Clamwin
• Spyware Protection: Spybot Search and Destroy, Spyware Blaster, Ad-Aware
• Hardware Firewall: Linksys Router
• Software Firewall: Comodo Personal Firewall
• Internet Browser: Firefox
• Downloading Practices: Exercise Caution

Employing these utilities requires ongoing maintenance, unlike the "set it and forget it" approach. I dedicate a specific day, typically Saturday or Sunday, to updating and running scans with each program.

Individual Utility Management

Clamwin automatically updates its database, but currently lacks real-time protection. Scheduled scans can be configured within the program.

Scheduled scans in Spybot Search and Destroy can be implemented through Windows Scheduled Tasks. I typically perform a manual scan approximately once per week.

I also manually update Spybot once a week to ensure it has the latest definitions.

Spyware Blaster is updated manually on a weekly basis to maintain its effectiveness.

Regularly updating Ad-Aware is crucial for its continued performance.

Firewall and Browser Considerations

A hardware firewall offers a more robust level of security than a software firewall, in my opinion. A suitable Linksys router can be acquired for around $50.

If you are utilizing a wireless network, ensure you employ WEP as a minimum security measure, with WPA2 being significantly preferable. Additionally, disable SSID broadcasting.

If a hardware firewall isn't available, utilize the built-in firewall in Windows XP or Vista. For enhanced control over outgoing traffic and programs attempting to connect to the internet, I recommend Comodo Personal Firewall.

Safe Computing Practices

Finally, exercise sound judgment. Avoid opening email attachments from unknown senders. Ensure your email client has an up-to-date spam filter.

Keep your Windows operating system current with automatic updates, although caution is advised with Vista; consider manually installing updates and waiting a few weeks to assess potential issues.

Always scan any downloaded file before opening it, particularly executable files. Your virus protection software will alert you to any detected threats. Avoid peer-to-peer networks like Kazaa, Bearshare, and Azureus.
