I guess I haven't run it lately because when I launched it today I discovered that there's a v 3.07, and a new subscription model. Still, I'd fire it up periodically and let it (slowly) go through my system looking for any malware. In all comparison tests the app falls in the middle to the back of the pack. In all this time it's found a grand total of 6 pieces of malware on my system - all old Windows malware embedded in saved html files.

It's been an okay app, a little slow, a little clunky-looking. When ClamXAV went commercial in 2016 I bought it immediately for $30 to support the developer. One thing to note: the scanning speeds, and the ramp up time before a scan actually begins are both hugely improved over v2. Those drive icons are a little too big and don't fit in well with the look and feel of a modern Mac, but to be honest, I don't spend my life inside the GUI of my AV software, so I don't really care too much about that. The UI could do with a little more polish, it's true. In each case for me, the constant updates and improvements, and decent licensing terms have been enough to persuade me to opt in. The only other two subs I maintain are for JetBrains products and Office 365. Not that I'm a fan of subscriptions, but in this case it's almost a no-brainer. Here we have a developer who cares about the Mac, who puts real effort into getting a quality program out, and yes, who asks to be paid for his work. Yes others are completely free, but from experience they also consume more system resources and are a PITA to remove. So not free, but so close as to make no real difference. £14.99 with the 50% discount and VAT removal (being a company purchase) for 3 computers over 2 years - it works out at a few pence per month.
