In the process, I found a DAT on McAfee's website. Specifically, it is SDAT4563. So I saved it to my desktop and copied it into my memory stick to bring to him.
Here is the problem. I cannot delete the file from my desktop. I continually get an error message saying:
"Cannot delete sdat 4563: It is being used by another person or program. Close any programs that may be using the file and try again."
I do not use McAfee, I use Symantec (Norton).
I do not know what possible program it could be using, and I want it off my desktop...it worries me.
