Smadav Antivirus Download for Windows PC [Free Download Smadav Pro 2023]

What is Smadav?

As a software specialist, I recently had the opportunity to test out Smadav, a unique antivirus program that is designed to run alongside another antivirus software. After putting it to the test, I can say that I was impressed with its performance.
Smadav is a product with its own software license that can be installed with another antivirus, making it a valuable addition to any computer’s security setup.

Unlike other antivirus programs, Smadav is designed to still allow you to install another antivirus while providing an extra layer of protection. It is especially useful for those whose computers are already infected, as it can detect and clean out any existing threats.

The pro version of Smadav is designed for main protection in your PC and can also fix any issues caused by another antivirus. It improves security by preventing the spread of infection from USB devices, and it can be a valuable tool for keeping your computer safe and secure.

Technical Characteristics

  1. Small Footprint – Installer size under 2MB and runs optimally even on older computers without lag due to very small memory and CPU usage.
  2. Real-Time Scanning – Advanced monitoring of opened files, apps, processes and system areas to detect threats before damage.
  3. Added Tools – Extra tools for file deletion, security, convenience and productivity like manage extensions, clean up junk files, view app passwords etc.
  4. Whitelist Facility – Option to exclude trusted apps and files from scanning to avoid false positives and speed up system.
Technical Characteristics



  1. Frequent Database Updates – New viruses originate daily and Smadav pushes out several definition file updates per-day for maximum protection.
  2. Works with Other Antivirus – Smadav is designed to complement your existing main antivirus solution for layered security. It can run alongside others.
  3. Bonus Privacy Features – The Pro version comes with extra tools like privacy cleaner to erase junk files/traces and open web anonymously through built-in proxy.


  1. Resource Conflicts – Though minor, some users have reported system crashes and freezes when Smadav quarantines suspicious files already acting upon by Windows Defender.
  2. Lack of Customer Support – Being a small product from a startup, some users find email-based assistance insufficient compared to 24/7 live chat support by big companies.
  3. Automatic Passkey Feature – Privacy advocates dislike antiviruses that silently whitelist other bundled software during installation. Smadav does this without consent.
