With the Pro version you get real-time protection and can schedule scans and so forth. As I remember it, you can also get a lifetime subscription for an additional $9.00 (not sure if this is still available or not, but was there when I checked it last). I'm currently using the free version which works just great with Jaws. I'm also using Malwarebytes' anti-Malware along with Superantispyware and I have a great combination along with Avast 4 Home Edition. I also have Spywareblaster installed on my machine. Stanley
