In many cases, people remain utterly unaware of the fact that their system has been compromised by a virus of this category. This is oftentimes due to the specific ways that these threats use to infect the computers of their victims. Oftentimes, it is the users themselves that allow (albeit unknowingly) the virus into their systems. For example, many Trojans travel under the guise of popular games or programs that are distributed for free on illegal file-sharing or torrent sites.
