My computer has Virut 32 on it. I am not sure how Virut 32 works.

I have an external hard drive that I copied two Virut infected exe files to. I did not run the files. I just copied them. There are no other exe files on the external drive, just the two that I copied. Is my external drive now ruined and infected with Virut? Or, can I fix the problem by simply deleting the two infected files from the drive.
