Despite the reference to a Windows technology, clicking "OK" in the error dialog will download a disk image file from a remote server, with a name such as cleanlive.dmg; Intego warns that several different filenames may be in use. This image may then attempt to mount itself, and launch its contents automatically.

Defense against the Trojan is possible by avoiding suspicious websites or refusing to accept the download, though if the ActiveX dialog is encountered, it becomes impossible to navigate away without closing a browser entirely. The Trojan should also in theory be recognized by various anti-virus programs such as Intego's own, which will halt the malware from being executed locally.
