Lo monakalo ungabuka ekulahlekelweni kwamafayela kuya ekulahlekelweni kokuphelele kokuvikeleka - ngisho nokweba ngokuqondile. Lolu hlu (ngaphandle kwe-oda elithile) lunikeza ukubuka kabanzi kwezinhlobo ezilimazayo kakhulu ze-malware, kufaka phakathi amagciwane , iTrojans nokuningi.

Ama-Virus Overwriting

Amanye amagciwane anomholo wokukhokha onobungozi obangela izinhlobo ezithile zamafayela ukuthi zisuswe - ngezinye izikhathi ngisho nokuqukethwe konke okushayela. Kodwa njengoba kubi njengoba lokho kuzwakala, uma abasebenzisi benza isinyathelo masinyane amahle amafayela asusiwe angatholakala. Ama-overwriting amagciwane , noma kunjalo, bhala ngaphezulu kwefayela lokuqala kanye nekhodi yabo enonya. Ngenxa yokuthi ifayela liguquliwe / lishintshiwe, alikwazi ukutholakala.

Ama-keyloggers angarekhoda zonke izinkinobho, noma angase abe yinkimbinkimbi ngokwanele yokuqapha umsebenzi othize - njengokuvula isiphequluli sewebhu esibhekisela kuwebhusayithi yakho yasebhange. Lapho ukuziphatha okufunayo kugcinwa, i-keylogger iya kwirekhodi yokurekhoda, ithola igama lakho lomsebenzisi nephasiwedi. Okuningi "

Ababuyiselwe emuva
