iAntiVirus

I'm not sure this is the right place for this question, but I couldn't find a more related topic.

Has anyone heard of or does anyone use iAntiVirus? It is a freeware program from PC Tools (they also offer a Commercial version). Link to their website: http://www.iantivirus.com/?utmsource=pctools&utm_medium=dhtml&utmcampaign=iav

They seem legit, but one never knows, so I'm hoping someone here has heard of them or has had experience with them.
