The really "fun" thing about getting one of your sites false-positive detected as a malware site is that pretty much all of the engines use EACH OTHER as data points, so once one of them flags you, all the others immediately follow suit... but they generally DON'T follow one another in terms of REMOVING false positive detection results.
So if eg Kaspersky sneezes, you have ten or more badly documented and completely different removal request procedures to follow.
