Dorothy, (sorry for the misspelling earlier)
At the start of this post you stated you had tried the scanner on another PC, this lead me to think what ever caused the problem could be a driver issue with W2K (that is the OS you are running, correct?). If so, then there may not be a trojan horse or anything more than a W2K issue. Know that does not make any easier to find, but you may need to find something in the registry. When the scanner was tested on the 'other' pc had any updates been applied to it? I would continue to search the Epson forums to see if this had been seen before and would bet that there some folks there that can assist you in getting it up and going.
Good Luck and keep us posted.
