Thaum nws nkag mus rau hauv lub khoos phis tawm, Trojan soj ntsuam cov kev ua hauv lub khoos phis tawm, sau cov ntaub ntawv thiab xa cov ntaub ntawv mus rau tus tsim tawm.
Raws li kev txheeb cais, feem ntau ntawm Trojans nkag mus rau hauv lub computer yog tshwm sim los ntawm cov neeg siv lawv tus kheej.

Qhov feem ntau pom ntawm Trojan nees yog: - email; - ICQ; - chaw muaj software uas raug nyiag siv; - Kev phom sij ntawm Trojan nees yog tias nws nce yuav luag tsis pub nkag mus rau koj lub khoos phis tawm.
