My anti virus software will not delete this virus because it's not allowed access to the folder. I think that message means that the file is in use, so there would be a process taking place. I have Windows XP and have not been successful finding this process or in editing the registry to get rid of the virus. Anyone hav any experience with this? It's called the "backdoor Sdbot" and its a Trojan if anyone knows what that is. Any help appreciated. PS I've updated Norton Anti-Virus so my definitions are up to date, it's just that the program won't allow access to fix it.
