AVG Antivirus Free is the only comprehensive free antivirus suite on the market these days. The free version of AVG perpetually protects your PC from viruses and malware attacks. AVG Antivirus Free, additionally contains some additional safety features like internet protection, Email protection and Firewall protection in real time.

In particular:

  • The AVG's link Scanner continually protects you from malicious websites that host malicious code.
  • The AVG’s Email Scanning engine protects you from emails that contain malicious attachments and therefore the Firewall engine protects you from hackers and alternative suspicious attacks.
  • The AVG's Firewall can protect you from malicious attacks.

Apart from these options, with AVG, you'll be able to perform scheduled scans on your PC during non operating hours and you ‘re continually updated with the most recent virus definitions.

Overall, AVG Free is a smart protection and full featured program, easy to put in and manage.

Avira Free Antivirus contains a robust scan engine that protects you from threats and has nice detection and removal results from separated labs. The program’s interface additionally includes a ton of configuration choices, like custom scan exceptions, scheduler, reports, etc.

Avira Free Antivirus is a robust antivirus answer in the last years, however it doesn’t contain some further safety features like Web or Email protections. * (The only choice for Internet protection is to install the Avira Browser Safety toolbar that is out there for Firefox & Chrome browsers).

Overall, Avira Free Antivirus could be a superb alternative for your protection. The program lacks further safety features, (like Email or Firewall protection) however it's a good choice to protect your computer for free.

* Note: Email and internet guard protection is enclosed by default in Avira Antivirus Professional version.

Microsoft Security Essentials / Windows Defender

Microsoft's Security Essentials (the name was changed to "Windows Defender" on Windows 8, 8.1, and 10) is both an anti-virus and anti-spyware program. The program protects your PC in real-time, is auto updated regularly, it doesn't take much disk space for installation and it doesn't slow down your PC.

Windows Defender is enabled by default in Windows 8, 8.1 & 10, unless your system comes bundled with another antivirus suite (commonly TRIAL) from the computer manufacturer. (In that case Windows Defender is disabled and you have to uninstall the bundled antivirus in order to enable and use it as your main antivirus).

MSE is available for free for Windows 7, 8, 8.1 & 10, in 25 languages and has received great score from several AV test labs.
