I am presently using the free version for periodic scans. Overall, I think the developers have done a very nice job. I like the program a lot. It bothers me a little that they won't let you turn off the splash screen in the free version. Unless you buy a license for the full version, you must waych that annoying splash screen every time you start the program. I think it is better to try and attract customers to your paid product by adding value to the product, not by annoying them into buying the product. Still, a great product overall. This is just one annoyance that detracts slightly from the experience.
