I'm giving TDS3 as try. I see the on-demand scanning feature is enabled in the Demo version. But I get the impression the real-time protection that might keep trojans from installing themselves while you work is not enabled. Or did I miss something in the documentation? Isn't that what is referred to as Execution Protection? In other words, if your not going to do a on-demand scan, is there any benefit to keeping the program loaded into memory?
