Pros / It is excellent at detecting security threats, both known and newly discovered malware.

Cons / It lacks online backup to help you restore your system in the event of an attack, though this feature is available with its premium security suite for a higher cost.

 Verdict / F-Secure Internet Security is a high-performance internet security suite with perfect scores in protection tests, but it lacks some highly useful security features.

Editor’s Note: Top Ten Reviews uses test results from the independent laboratory AV-Test as part of our review process for the best internet security suites software. AV-Test looks specifically at protection, performance and usability on multiple versions of Windows operating systems, and it performs these evaluations several times throughout the year. We use the most current AV-Test scores available at the time of our review. It is possible that new AV-Test scores will be released after our review goes live on the site. We will consider these scores during our next review of the best internet security suites software.

F-Secure Internet Security is among our top 10 interment security suites because of its great performance in recent testing by independent software lab AV-Test. Many of its competitors, however, have a few more features to improve security, which prevents this internet security program from ranking higher in our review.

AV-Test included F-Secure Internet Security in the 22 home-user security products it continuously evaluated during March and April 2016 on Windows 10 test computers. F-Secure earned a perfect score in protection for correctly identifying and blocking nearly 23,000 known and new malware threats. It also scored above average for mistakenly blocking only three out of 1.2 million good websites, thinking they were threats. Compared to the industry standard, running F-Secure internet protection does not slow down your computer significantly as you surf the web, copy files and use applications on your desktop.

Even though F-Secure's malware prevention performance places it among the best security software, a lot of products ranked higher in our internet security review for their included feature sets. F-Secure does include many important tools, though, such as instant scans of email and USB drives for threats. It also includes a gamer mode that knows when you are playing online and suspends some functions to keep your computer running at full speed and not bother you with permission and reminder pop-ups.

F-Secure has parental controls that let you determine when your children can access the internet. It also lets you block harmful websites and content so that your children can't view them. This is an important security feature that not all internet security suites include.

Some features missing from F-Secure are a firewall to boost security and a password manager to protect your passwords in the event of a hack. It doesn't have online backup capabilities either, which would be helpful in the event your computer is attacked and you need to reset your files and programs to the way they were prior to infection.

F-Secure Premium Security Suite

F-Secure SAFE has all the important protections found in the basic antivirus software plus the extra features of the internet security program. As F-Secure's premium security suite, SAFE includes additional tools that make it a more secure product. Two extra features in F-Secure SAFE are a virtual keyboard and online backup.

With online backup, your computer system automatically saves your files and applications in the cloud. In the event that your computer is hacked or infested with malware, you can rescue your system and restore it to its original state. This is better than using a rescue CD that is subject to the information last saved on it. Online backup has more current information, so you don't lose as much, if any, important documents, search history and applications.

The virtual keyboard allows you to log in to online banking, email and other password-protected sites with added safeguards to your passwords. Using the virtual keyboard secures your passwords from being swiped by hackers looking to steal your identity. F-Secure has a second layer of defense available, a password manager, that gives you a secure place to keep your passwords and access them when you forget or need them. However, the password protector is not part of F-Secure SAFE and needs to be purchased separately.

One extra feature that is not included with F-Secure SAFE but is found in the best premium security suites is a file shredder. This tool completely eliminates any virus or malware threats from your computer. Programs without this tool simply isolate the threat to prevent it from infecting your computer.

F-Secure doesn't offer as many support options as most other programs in our review. It has phone support, but only during weekdays. It does have live chat support, though this too is limited to weekday hours. It also has a useful knowledgebase to help you identify common malware threats and learn how to avoid them, as well as how to install F-Secure Internet Security.

F-Secure is a good product because it is so effective at detecting and stopping malware. It works against both known and unknown viruses. Competing products have a few more features, but F-Secure does include parental controls and a gamer mode.
