Due to an exploit in Apple's Remote Desktop Agent, a new 'trojan horse' has surfaced for Mac OS X; and with it, appeals from Anti-Virus software companies claiming you need to buy a product to protect yourself. The truth: this trojan horse, so far, has not been documented in the wild, and in fact, we find it highly suspicious that multiple Anti-Virus companies have been able to get a hold of it.
ARD Patcher is a small application that will patch the exploit, free-of-charge, as in reality its a simple patch that Apple will surely fix in an upcoming update. Getting an antivirus program is overkill in this situation, despite what all those companies will tell you. Note: This does *not* disable Apple Remote Desktop, unlike some of the other fixes circulating around the internet, this one will neither require disabling ARD nor enabling remote management.
Version 1.1: added advanced option to disable ARD all together.
