I've read some of the previous threads and looked over the Ewido web site, but I have a question for those using the free ESS. Since the free ESS is only an on demand scanner, does ESS load any processes in the background at system startup? I prefer not to have anything running in the background, unless I initiate it, since to me that defeats the purpose of a on demand program, and besides, why use resources for something you don't want running. As you may have guessed, I'm looking for only a on demand AT. Thx for your replies.
