F-Secure Anti-Virus 2013 is a straightforward and effective antivirus engine which will do its best to keep all malware locked firmly out of your PC.

And "its best" is often very good indeed; F-Secure Internet Security 2013 was ranked as offering 100% effective protection in an AV-Test report from July 2013.

Install the program and it'll begin to protect you right away. Any files you access are checked for potential threats, and F-Secure's DeepGuard technology (enhanced to version 5 with this release) keeps an eye on the behaviour of all running processes, looking out for any which might be behaving suspiciously. This raises a few more alerts than we'd like, just initially, but once you've told it which programs to trust then things soon settle down.

You can of course also launch on-demand scans, though, either from the F-Secure console or by right-clicking the appropriate file or folder within Explorer.

A scheduled scanning option allows you to run automated checks on a daily, weekly or monthly basis, or just whenever your PC has been idle for a specified amount of time.

And all this comes presented in a redesigned and much simplified interface. Whether it's "better", we're not quite sure; it seems like there's less clutter per dialog, but you may well have to look through more dialog boxes to find what you need.

Don't let that put you off, though: the jury may be out on the new look, but the core antivirus engine is great.

Verdict

A straightforward and easy-to-use way to protect your PC from malware
