AntiTroy is a rogue antispyware program. It is usually distributed through the use of trojan that come from fake online malware scanners or websites like youtube that ask users to download a fake codec or an update of Adobe Flash Player needed to view a video online.

These files are absolute harmless but AntiTroy during the scan reports them as infections to make you think that your computer is infected with a lot of spyware, worms, trojans and other viruses. Of course, the scan results are fake, the rogue is unable to detect or remove any infections nor will be protect you from legitimate future threats.
Last, but not least, the same trojan that installs AntiTroy will download and install a trojan FakeAlert.
