My wsock32.dll file has become infected with a virus. I detected this when I ran McAfee virus scanner. I downloaded instructions from the McAfee home site and the instructions tell me to rename wsock32.ska to wsock32.dll, but when I go to DOS and give the command to rename, I get the message duplicate file or file in use and will not rename. In explorer, under windows/system folder, I find the wsock32.ska file, but not the wsock32.dll file. I have tried to rename there with the same results.
When I run my virus scan and the ska virus is detected, I cannot clean or delete. If I cannot do any of the things above, what is the definitive answer?
