I got what appears to be a Netsky infection. I also can't seem to delete a folder in my exchange server. MacAfee found 7 infected files. TDS3 found 1 trojan in a video folder. But once the o/s was turned on Exchange Begin dumping badmail. One of the problems I found was in the recovery dir. A user which is not part of the system, actually I can trace that user to a server that has been removed from the network. Anyhow that user deleted the badmail folder back in Oct. last year. I followed a MS process to kill the recover dir. but I couldn't complete the task. I went to the DOS shell and used the ATTRIB command to show hidden files. I kill everything I could see. Now the recovery dir has two dir.. but I can't clean them. When I use the o/s explorer I can see a SID file related to a user and in there are the BAD and BRD files that where deleted months ago. I think this is one of locations the virus is spawning. Just a few minutes ago Norton pickup the netsky virus in a exchange queue file.
