Common questions

Is the built-in protection enough?
For a careful user on an up-to-date system, often yes. Paid suites earn their place mainly on phishing blocking and on covering several devices at once.
How do you measure detection?
We run the same sample set against each product on a clean machine, then repeat it a month later with samples that did not exist the first time. A product that scores well only on old malware is not much use.
Does a paid suite slow a machine down?
Less than it used to, but the difference is measurable. We time a cold boot and a large file copy with each one installed, and publish both numbers rather than a verdict.
