file->save as...or find a site from an AV vendor that lets you download it as a zip or other format (like text, since it's just a text string) and save it as such. – Bart Silverstrim Oct 13 '10 at 14:50

You don't need to download it. Just open up notepad and paste the following into the file:

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

Then, save it as whatever file you want. You'll probably need to temporarily turn off your AV to handle the file though.

This comes from the EICAR Anti Malware Test file page: https://www.eicar.org/?page_id=3950

You could download the EICAR test virus pattern to a file and rename the extension to what you need.
