Okay.. sorry for posting so many questions in the past. However, I am destined to find out the truth about F-Secure's scanning engines and the quality of them. Okay as far as I know F-secure uses 3 scanning engines in one module. These scanning engines are : F-prot/AVP and Orion. Now, do you believe that F-Secure is made stronger by using these three scanning engines as opposed to just running the individual AV such as F-prot or AVP? What are your beliefs? I am willing to buy F-Secure and pay for the extra amounts, so long as it proves to be secure and worth the money. From my past experiences KAV has been too slow for both on-demand and realtime when scanning archives. F-Secure has run perfectly on my OS, which is win2k.
