Modern Endpoint Protection

Do You Need Antivirus?

In 2025, the answer is nuanced. Modern operating systems include decent protection, but dedicated solutions offer additional layers of defense.

Windows Defender

Built-in Windows security is now quite capable. For most users, it's sufficient when combined with safe browsing habits.

What to Avoid

Red Flags

Avoid: Norton (bloatware), McAfee (aggressive upselling), any "free" cleaner tools, anything with "optimizer" in the name.

Beyond Antivirus

Modern threats require more than signature-based detection:

  • EDR - Endpoint Detection and Response
  • XDR - Extended Detection and Response
  • Behavior analysis - Catches unknown threats
  • Cloud sandboxing - Safe file execution
