The only disadvantage of Trojan viruses lies in their name - they cannot spread without victim's consent. In last years, users think that any malicious or unwanted tools are viruses, but strictly speaking, viruses, unlike Trojans, can automatically spread and get into the unprotected systems.

But, if you'll assist your antivirus to act, and won't prevent him from working, the system will be protected. There are two ways to achieve this effect:

  • The safest choice is to fully quit using tools of dubious origin. These principles concern all the utilities downloaded not from the official developer websites or licensed distributors. Of course, the pirated replicas of paid software also are potentially dangerous.

  • If you are not ready to absolutely abandon the use of not official utilities, you should thoroughly inspect each downloaded tool. Trojan viruses usually lurk beneath the guise of good tools such as system optimizers, browser games, search engines, browsers, driver updaters and AV programs. Don't install suspicious utilities from this list, and while any unlicensed program is installing - watch closely at the installation, canceling all suggestions for downloading extra programs.
