One of the pioneers of free antivirus software for Windows, AVG has consistently won awards from AV-Comparatives over the past decade — including Top-Rated Product in their most recent test. It's unlikely anything is getting through this.
Avira has been creating antivirus applications for a long time, with the first one dating back to Bitdefender protects millions devices around the world and is consistently recognized by independent test labs like The Independent IT-Security Institute.
Russian cybersecurity firm Kaspersky has faced allegations of inappropriate connections to the Kremlin , prompting the US , the UK , and the Netherlands to ban the use of Kaspersky products across government agencies.
Nevertheless, the allegations remain inconclusive, and Kaspersky is consistently a top-rated antivirus product. If this app is already on your PC, you might be wondering why you should even bother with a free third-party antivirus solution. Its malware detection capabilities have improved, and it performed well in hands-on testing.
Still, PCMag gives it a rather lukewarm review:. Many free third-party apps are more effective at keeping you safe. The company will continue to support the antivirus software for the time being, but their overall support for Windows 7 has ended, and they recommend you upgrade to Windows Essential protection: PCMag reports that Sophos achieved excellent scores in their hands-on tests and excellent protection against malicious websites.
But unlike the other major players on this list, Sophos has few independent lab test results to prove its efficacy. Sophos also received a poor phishing protection score from PCMag. It's extremely short on features, though, and we'd like to see more coverage from the testing labs, too.
So here are few more antivirus products to consider:. Essential protection: Adaware Antivirus Free has received mixed scores in past independent tests, and PCMag cautions that Adaware has no recent test scores to show. And for an antivirus, protection should always be the 1 concern. Check Point ZoneAlarm is a free antivirus-firewall combo that licenses its antivirus engine from security giant Kaspersky.
Essential protection: Pairing strong antivirus prevention with a firewall can be good enough for basic computing. Features: Unfortunately, this free cybersecurity solution is missing many features you would expect to see, such as web-based security, protection against malicious websites, and personal data protection.
Essential protection: Qihoo formerly used the same core antivirus as Bitdefender and Avira, but it no longer does.
Sadly, its malware protection has suffered for it. Features: Qihoo comes with an impressive suite of bonus features, including cleanup and tuneup utilities, an adblocker , and more.
