ITD
Literally an 'Internet Transmitted Disease'

A Worm, Trojan, Malware or other noxious item that infects your computer and causes it to possibly become inoperable (and thus need cleaning/reloading).
Oh, Lord, now you know why I don't open attachments from people I don't know or get stuff from random sites. All those ITDs you can get.
