I just scanned my PC with the the latest 4.x version of The Cleaner (Free for 30 days from
www.moosoft.com) and found that a couple of ioFTPD sites that I had backed up to .RAR files contained the 'Aristotles' Mirc trojan in the program hidewndw.exe - which was used for hiding the eggdrop bot window.
I didnt setup these sites, so i dont know where this file was sourced from, but if you use this program, please scan it with a proper trojan detector like Moosoft. Dont rely on your normal AV software to pick this up.
