Having an antivirus to protect your PC and mobile devices is essential. And while a full-fledged antivirus usually requires an investment, there are a handful of truly free antivirus options to consider as a light or short-term solution, depending on your needs. We did some investigating, and here’s what we found:

The following free antivirus programs by leading cyber security firms offer decent security without a fee.

  1. Total AV Free Antivirus
  2. BullGuard Free Antivirus
  3. Panda Free Antivirus
  4. BitDefender Mobile Security Fre
  5. ZoneAlarm Mobile Security Free

1. Total AV Free Antivirus

Total AV Free Antivirus

Total AV offers excellent protection for your PC and mobile devices, with a particular focus on security. This free antivirus ranks high across the board for malware protection and boosting performance, however it lacks valuable real-time protection and its bonus features are locked behind a paywall.


  • Easy and simple user interface
  • Very fast scans
  • Finds and removes any duplicated files
  • No impact on performance
  • Good phishing protection


  • No real-time protection
  • Requires signing up for an account
  • No quarantine option for the free version
  • Some false positives
  • You have to pay for advanced features, such as a password manager or VPN

Total AV Free Antivirus offers some handy tune-up features with an easy-to-use interface that’s great for beginners, but other than that it’s pretty limited. You have to pay to use its bonus features, including real-time protection, so if you’re looking for this, you may be better off looking elsewhere.

2. BullGuard Free Antivirus

BullGuard Free Antivirus

BullGuard excels in spotting known-malware and utilizes new techniques to spot new threats, including ransomware, dodgy websites, Trojans and more. You’ll have to enable the parental control features for the best protection, though.

While not strictly free, BullGuard offers a 30-day free trial – one of the longest free trial periods of any antivirus on the market – and the software uses the same core detection system used by its premium range. Great if you want to give it a try first.


  • 24/7 support
  • Automatic scanning
  • Robust parental control tools
  • 30-day money back guarantee
  • Fast vulnerability scanning with risk alerts
  • Gaming mode
  • Doesn’t require an account
  • Extended ransomware protection


  • High number of false positives
  • No password manager
  • Having full parental tools running slows down your device noticeably
  • Console shows the premiun features even though you can’t use them

BullGuard protects your Windows machine against just about all types of threats, including rootkits, malware, and phishing scams. While experienced users are able to tweak the features as needed, beginners will be able to just turn on the antivirus to run quietly in the background. Simple.

For a free antivirus, Panda is one of the best with some handy extra features thrown in for good measure.

3. ZoneAlarm Free Antivirus

ZoneAlarm Free Antivirus

ZoneAlarm Free Antivirus offers as much protection as some premium security suites, particularly for those who spend a lot of time online. The software is highly customizable and offers an excellent firewall, and three scan types to suit your needs.

Free Vs. Paid Antivirus

Free antivirus programs get a lot of negative press, mostly that they can’t be trusted for full protection. However, most free antivirus software uses the same core systems as their paid counterparts.

The differences lie in the additional features that make up each security suite. While some free antivirus programs offer extra security, they often lack the full range of extra elements.

Free Antivirus Programs Often Don’t Include:

  • Technical support
  • Protection from complex infection types such as ransomware, rootkits, and phishing
  • VPN services
  • Security from some zero-day infections

It’s great to get paid protection if possible, but free apps are a worthy alternative. You can also use the free trials for premium software if you ever need an added security boost.

Excellent Protection at No Extra Cost

Staying safe online is anybody’s given right. While many decide against premium security products because of the cost, it doesn’t mean you should forgo protection altogether. Free antivirus apps are an excellent alternative and will keep you safe from the vast majority of threats.

We recommend Total AV as the best free option as it offers a wide range of security features that rival some paid plans. However, all the options on this list provide high-levels of protection and are easy, quick, and straightforward to use.
