I used the free version for a while, which I found to be very good. I like the plain, light-weight tree-based UI and the fact that it uses less RAM than other anti-virus programs, whilst still be fast and having excellent detection abilities.
I bought the premium version, which doesn't appear to be significantly different from the free version, because I wanted priority support and also to help support this excellent software, which gives about 40% of the cost of the premium software to charity.
This software is made in Germany, which goes some way to explaining how it can be so powerful, yet so very efficient with its use of system resources. It more powerful than Norton, whilst using 1/4 of the RAM and costing 1/4 of the price. Excellent!
