Pros / F-Secure’s pre-installation scan removes infections from your computer before the main application installs.

Cons / This program doesn’t scan USB-connected drives or devices.

 Verdict / Its solid protection and sleek interface make F-Secure a good antivirus software option.

With its advanced technology and integrated security features, F-Secure Anti-Virus protects against viruses, spyware, worms, Trojans and ransomware. It also locates and eliminates rootkits and protects against viruses spread through email and cookies. Based on our own tests as well as test results from third-party laboratories, including AV-Test and AV-Comparatives, F-Secure is among the best antivirus software for Windows.

F-Secure’s clean, sleek interface makes the program easy to navigate, and it’s easy to schedule specific scans or adjust settings. The main dashboard lets you quickly access scans, tools and statistics, and most of the time, F-Secure updates and runs scans automatically. The program also scans compressed files as well as email attachments and messages.

When you first download F-Secure, the program uses the Cleanup tool to do a quick virus scan to see if there is any malware already in your system. If it finds any threats, the software takes care of them before the full program installs. You can also use the free scanner on F-Secure’s website to locate any current threats on your machine before you purchase the full product.

F-Secure’s biggest shortcoming is it doesn’t automatically scan USB files, which is a pretty common way for threats to enter your system. However, the program is quick to identify malware and can block these threats before they embed themselves in your computer system – it received an average 99 percent effectiveness score for detection and removal. You can also choose to manually scan USB files.

The software uses a protection network to collect information on new threats, also known as zero-day threats, and pushes out updates to its users to ensure their computers are protected against malware as it’s discovered. This network helps keep your antivirus software current, and F-Secure automatically updates itself.

If F-Secure finds a potential threat but isn’t completely certain it’s malware, it places the file in its secure Quarantine file. You can look over the quarantined files and mark those you know are legitimate as safe. The program automatically deletes quarantined files it determines to be malicious and removes them completely from your computer.

Though F-Secure does a good job protecting your computer from malware, it uses a lot of your system’s resources. When we performed our in-house tests, we noticed several seconds of delay, which was frustrating when we tried to attach files to emails, open applications and play games online. It didn’t seem to affect computer speed when we watched videos online after we opened them. Our results are similar to those reported by third-party testing labs.

When you purchase the basic F-Secure Anti-Virus for PC package, you can install the program on a single computer or laptop, which is standard for antivirus programs. You can purchase three licenses at one time, though they can only be used for computers since this version of F-Secure isn’t compatible with mobile devices. However, the company makes more inclusive products, such as F-Secure SAFE, that are compatible with both computers and mobile devices.

Though it didn’t receive top marks in all the areas we tested, F-Secure Anti-Virus for PC is beneficial in quite a few ways. It protects PCs from viruses, spyware and other sorts of malware, including ransomware threats. In addition, it updates itself automatically, so you’re always protected against the most recently discovered threats. The software doesn’t automatically scan files on USB drives when you insert them into your computer, but you can select a custom scan option to check these files before you open, download or save them to your computer.
