As a former server administrator, to me, any time that Perl can help solve a difficult administration problem is an instance of a "cool use" for Perl. Reading your post, I was glad to see I'm not the only one who looked to Perl for help with Nimda.

In the first hours after it first came out, while AV manufacturers were still getting their updates for it stabilized, I wrote a short script to help our webserver administrator out in cleaning up webpages on an infected server (Nimda, at least the versions I have encountered, append to web pages JavaScript code to open a window containing its code a considerable distance off-screen, as another way of transmitting itself). The script would look for the JavaScript code (with some variation allowed), and convert it to HTML comments (in case we found it had been converted in error). (Sadly, though, the script was on a machine that has since been reloaded, and thus was lost.)
