What is the best new antivirus software?

Windows 10 comes equipped with two apps — Windows Defender and Windows Firewall — that do a great job fighting against viruses and other types of malware. Many users will say Defender and Firewall are all they need, while others want a third-party option handling their PC's security.

If you're interested in taking your security to another level, check out this roundup of the best antivirus software available in 2017.

Kaspersky Total Security

Kaspersky Total Security 2017

Kaspersky's most complete antivirus software comes, as the name implies, with Total Security. This suite of tools is designed as a sweeping safeguard for you and your PC — unlike other antivirus software, Kaspersky Total Security includes a kid-safe mode to protect your young ones from inappropriate content and messages, a built-in password manager to keep track of your ever-expanding list, and an online backup to keep your files safe.

These features are, of course, an added bonus to what you'd normally expect out of antivirus software. You're getting a firewall to protect against unknown connections, adept anti-malware security to catch viruses before they infect your PC, and anti-phishing protection to help keep your personal information safe.

If you don't mind spending a premium amount for your antivirus software and you need something that works on multiple platforms, Kaspersky Total Security is where it's at. It starts at about $60 for one year of protection, and it can be installed on up to five devices. It is compatible with Windows XP and later, as well as macOS, iOS, and Android.

Webroot SecureAnywhere AntiVirus

Webroot SecureAnywhere AntiVirus 2016

Webroot SecureAnywhere AntiVirus is an interesting package — its signature database is stored in the cloud, which means it only takes up about 2MB of space on your hard drive and doesn't require constant updates. It also only takes up about 4MB of RAM during system idle, which is especially important for those of you that don't have much RAM to spare.

Here's how the cloud-based Webroot SecureAnywhere AntiVirus works: new files and programs are scanned and their signature is sent to the cloud to be analyzed. In the meantime, the file or program in question is kept in a quarantine state with some of its function unusable. When Webroot determines the file or program to not be malicious, the quarantine state is lifted. If you don't have internet access, programs and files you've previously accessed on your PC remain usable, but new ones will be placed in the quarantine state until you reconnect to the internet.

On top of malware protection, you're getting anti-phishing tools to protect your private information, webcam protection to protect you from spying, and incredibly fast scans of your PC.

If you're someone who is always connected to the internet and could use the extra space on your hard drive, have a look at Webroot SecureAnywhere AntiVirus. It starts at about $30 for one year of protection, and it can be installed on up to three devices. It is compatible with Windows 7 and later, as well as MacOS.

Avira Free Antivirus

Avira Free Antivirus

Just because Avira Free Antivirus is, as the name suggests, free, doesn't mean it doesn't offer great protection and a ton of customizable options.
