What is antivirus software?

Yes, antivirus keeps your devices safe, but what exactly is it? Antivirus software detects, prevents and removes any form of malware on your device. This includes computer viruses, spyware, adware, ransomware, Trojans, worms and spam. Any malicious software a hacker concocts, its an antivirus’ job to thwart its devious plans to steal your data.

As for how it works, an antivirus will scan through everything on your device, including software, applications, files and even web pages, to make sure its free of malicious code. If malware is found, it will block the threat, warn the user it’s on their device and remove it. It’s like having a digitalised version of top secret agents whose sole purpose is to search and destroy.

Antivirus software will perform different types of analysis, including specific analysis, pinpointing familiar malware; generic analysis, recognising parts of known malware code; and heuristic analysis, which searches for unknown, threatening malware that follows the usual malicious routine. Cybercriminals may continue to construct new strains of malware and exploit zero-day vulnerabilities, but cybersecurity experts stay one step ahead.

Researchers at AV-Comparatives test a number of antivirus services, giving them a score from Standard certification to Advanced+ certification. The latter is awarded to software that goes above and beyond just passing tests, which include real-world protection rates, online malware protection and detection, offline detection and the impact on a device’s performance.

1. Norton 360

Best overall antivirus software

Best antivirus: Norton 360

“Norton” and “antivirus” are synonymous these days, as the well-established cybersecurity brand has successfully fought against malware, viruses and nasty software threats since 1990. 

Norton 360 offers excellent antivirus protection and extra features that make for a valuable, all-in-one security product. Its Norton 360 Deluxe and Premium package may cost a pretty penny. Still, with security across multiple platforms, a full-blown VPN, Dark Web Monitoring, Parental Controls and more, it will have a household free of cyber threats. 

Norton’s certainty of its antivirus software’s capabilities is clearly defined by the brand’s 100% Virus Protection Promise. If a device protected by Norton 360 can’t get rid of a virus, the user receives their money back. It’s a big claim, but unquestionably, no one should expect to get that refund.

If you have the money for it, you can also check out the premium Norton 360 Platinum package for even more online protection, including from identity theft.

2. AVG

Best free antivirus

Best antivirus: AVG

You can never go wrong with free antivirus protection, but some deliver even better detection and protection rates, along with extra security features, without costing a dime. This is where AVG antivirus shines.

AVG provides reliable protection and only a small impact on performance for Windows, Mac, iOS and Android. It safeguards your devices against malware, viruses and zero-day exploits, along with blocking malicious links and attachments in emails. Throw in phishing protection when surfing the internet and extra security features such as its SafePrice browser extension and Network Inspector, and you’ve got yourself a do-it-all antivirus.

Sure, you can find all of these perks with other free antivirus software like Avast, but if you like a slick, darker user interface that’s easy to navigate, then AVG is for you.

5. Malwarebytes

Best antivirus for Windows PC

Best antivirus: Malwarebytes

Hundreds of malware emerge every minute, and it’s Malwarebytes’ mission to detect and conquer them all. Does the antivirus do this successfully? Yes, but there’s wiggle room for improvements.

Malwarebytes’ no-nonsense approach to protecting your devices from the onslaught of malware and viruses is effective for those who need a reliable antivirus that will detect and remove malicious software, especially with its free version. However, while its premium service provides 24/7 real-time detection, conveniently blocks vicious ransomware and shields users from malicious websites, it doesn’t go beyond on the feature front.

That’s no bad thing, as sometimes a user only needs a powerful antivirus to keep them safe from cyber threats. But considering its competitors add a few more security tools, such as data breach monitoring and a firewall, there’s room for improvement.
