Free antivirus software is an excellent option if you just require a basic level of protection however, be aware that they’re unlikely to offer the same degree of protection as premium solutions. The top free AV software will often offer top malware detection rates that are endorsed by independent labs such as AV-TEST or AV-Comparatives. However, they don’t have the extra features that are typically included in premium software. These extras, such as security measures for network threats and usage profiles, a VPN, password managers, and parental controls can be crucial to complete online security.

Furthermore, free antivirus programs might not be updated at the same rate as paid ones, which leaves a window of opportunity for spick and span baddies to get past detection. Most free antivirus programs rely on signature detection that involves checking malware samples against strings of characters associated with known attacks. This approach is successful if attackers have used the same patterns. However, sophisticated hackers are increasingly employing techniques that are unique enough to avoid detection by traditional signature scanning tools.

You should also take into consideration the terms of service for a particular antivirus program. The majority of free programs are licensed for personal use, and may not be suitable to business users. Some free solutions include technologies that could be classified as adware and spyware. Downloading these should be done with caution. Paid solutions, on the other hand tend to be supported by guarantees and warranties that specify what rights the user has to in case of a breach or infection.
