I am having problems updating the radius file. I click on the manual link and save as. It downloads and I save it but when I run TDS it gives me a warnng that radius file needs to be updated. I am having big problems with trojan horse IRC/BackDoor.Sdbot.45AZ. I upgraded my computer (box only), was having a MS serious error messages, downloaded SP2 and total crash. Now I have the above trojan. Can't understand why the warning re updated file. I am not very knowledgeable about computer stuff! Thanks for any help.
