It's good to know there are free editions so that you can use it because it's free.
If you have other programs which check for viruses and other malware problems then this should be sufficient.
If you need the additional features of the professional versions then you should get it.
I prefer the free edition myself because I have other programs checking for the other features.
That said I'm still looking for a better program because it doesn't complete its scanning feature which means I don't know if it's doing its job properly.
