I have a small folder of "virus killers" that I put on clients' computers routinely, to be used as needed. Today I copied this folder onto the client drive and an existing copy of Norton on the computer popped up and said it found trojan.gen.2. Drilling down further, Norton reported that it was contained within my copy of rkill.exe in the virus killer folder.
Is this likely and/or possible? Is my copy of rkill (which seems to work correctly) infected? Of course, I've deleted it, but I've not had this problem before.
