[Plugin: WordPress File Monitor Plus] Leftover files in server when using WPFMP with Cron

I’ve been using WPFMP with Cron, and I just noticed that every time it runs, a new file is generated on the server. There are hundreds now. The name of the file is in the following format:
index.php?sc_wpfmp_scan=1&sc_wpfmp_key=ce4301e4eccb788d9c7fe25e83eea4272db8f504.1

and the content is simply “Scan Successful”

I tried tweaking my cron command, adding a “quiet” parameter to wget (-q) and redirecting the cron output to dev/null, like this:
wget -q “http://domain.com/index.php?sc_wpfmp_scan=1&sc_wpfmp_key=dd4301e4eccb788d9c7fe25e83eea4272db8f504” >/dev/null 2>&1

…But still no success. I know this is probably not related to the plugin per se, but you’re the first guy that I figured might know the answer.
Do you have any idea how can I avoid these files from being generated?
