The SystemCrash trojan is a fake threat displayed by some rogue-promoting Zlob clones, most notably - Winsurf.The best way to tell if you've been infected by this parasite is this: if you encounter a popup or fake system notification, which says your system has been infected by this trojan. This is a deliberate attempt to mislead you so that you'd buy the "licensed version" of whichever rogue is being promoted. One of these rogues is MalwareBell, but the SystemCrash trojan may belong to some others as well.
