F-Secure is also quite lightweight, with little impact on boot time, and has a memory footprint that isn't too high. Disappointingly, though, when it came to straightforward malware, F-Secure's performance was one of the least impressive this month: its score of 90% landed it in eighth place. It also took an annoyingly long time to clean up malware on some occasions, keeping us waiting for more than two minutes while it "processed" the infected files - even when we'd asked it to simply delete them. And it complained on three occasions during our false-positives test.

We were also irritated by the fact that, when parental controls are enabled, you have to enter the parental password every time you want to access the F-Secure interface. No other package was as intrusive about this.

To cap it all, it's pricey for a relatively limited feature set at £52 for a single PC licence. Although the F-Secure philosophy is certainly appealing, its other weaknesses mean it isn't top of the charts in this Labs.
