When it comes to the world of free antivirus, Avast is one of the best candidate out there. Avast is well known in the market for a long while now and it is very effective at detecting and blocking suspicious and malicious programs as well as blocking malware and phishing tools that might appear in browser. Avast’s free solution is capable of running automatic scan on PC or notebook to check for security problems. Additionally, it’s also bundled with a password manager, a system cleaning tool, a outdated software updater and recovery disk. Ok, it’s not perfect, the system cleaning tool and the software updater is junk at the very least and if I am provided with the option, I will opt out of installing those.

Although you can use Avast Free Antivirus without paying, you need to register an account to use it (after 30 days). However, it should not be a problem, after all they are providing a free service. Another thing is, free version of Avast doesn’t comes with “Deep Scanning” feature which is really important if you want to detect threats prior to the antivirus installation. The real-time protect is available to contain the machine from new threats, but it doesn’t overcome the lack of deep scanning.



  • Comes from a trustworthy source.

  • Needs you to register an account to continue using free version.

The low hardware requirements are also one of the key feature of AVG.

The AVG antivirus is specially brilliant at detecting and protecting against phishing attacks. Moreover, it scans your PC to find any security problem very quickly.

  • Provides additional tools to monitor processes and use devices.


  • The free version has several locked features.

Bitdefender Antivirus Free Edition

Bitdefender Antivirus Free Edition is an interesting option because unlike the others, it is more discreet. Bitdefender runs entirely in the background and requires the modest amounts of configuration setup to get started, meaning it provides silent installation feature. So this can be a good start for a less tech-savvy person who doesn't want to go through a lot of checkboxes to use an antivirus.

ZoneAlarm Free Antivirus

ZoneAlarm is perhaps the least known of all the solutions listed above. However, it offers tools that can be enough for your type of needs: a very strong firewall, the option of storing 5GB of cloud files, real-time monitoring and identity protection.

Unfortunately, the phishing protection of ZoneAlarm is not up to the mark, but it does notifies the user of sites and applications of suspicious behavior. In this way, you can judge whether it is valid access or use.
