Computer viruses, and malware come in nearly all forms nowadays. From phishing emails with offers too good you can’t resist, to spyware, and others that outright cut your device access. And while most devices nowadays feature built-in protection, it’s not enough.
Luckily, there are plenty of awesome free antivirus software you can maximize to enhance your device’s safety. Here are ten of the best free antivirus software we recommend.
1. 
Kaspersky Security Cloud Free
Kaspersky has one of the most feature-packed, and also the best antivirus software in the market. The Kaspersky security cloud free is an update of the Kaspersky free AV and looking at what it has to offer, it indeed is an update.
To begin with, it uses the same malware-scanning technology used in the paid version to detect malware. This not only results in comprehensive malware prevention, but also removal. We also loved that it includes a system watcher, a feature capable of not just detecting, but even reverse the impact of ransomware.
Gamers will love it even more because it also includes a gaming mode to prevent notifications, and other interruptions.
Where most free antivirus software outright deny users password management, Kaspersky allows free users up to 15 password entries, and a limited-usage VPN. Hotspot Shield VPN users on Kaspersky free users get 300mb of free and secure data connections they can use to tap into the former’s infrastructure.
This free antivirus also automatically adds browser extension to Chrome, and Firefox browsers, protecting users from malicious URLs, ads, and cookie trackers. Kaspersky free scans are also quick. Free version users get the full scan which comprehensively scans, and identifies malware, and a quick scan whenever they need to conduct a quick check of their device. Kaspersky Cloud free also runs free background checks on USB flash drives for malware and ransomware.
The interface is well-laid-out and even displays a red exclamation mark for items that might need attention. This makes checking for threats exceptionally easy even for the first-time user. The catch? Free features for Mac and iOS users are limited, plus you get no direct customer support. But in a nutshell, it’s one of the best antivirus software we came across.

Other than a free antivirus, free trial users also get online threat prevention. It features a web filter to scan, and block malicious sites, consequently protecting users from phishing, and spam attacks. The advanced threat defense feature takes security to the next level. it uses machine learning to detect, flag, and notify users of software with suspicious activity, for instance, making unauthorized system changes.
Bitdefender free trial users also get full customer support via phone calls, emails, chats, and even community forums. They also get updates sent out daily. The best part?
