Kwihlabathi le-antivirus, isayinithi yintetho ye-algorithm okanye i-hash (inombolo ephuma kwisiqalo sesicatshulwa) esichaza ngokukhethekileyo intsholongwane ethile. Ngokuxhomekeke kuhlobo lokutshekisha isetyenzisiweyo, lingaba yintsimbi ye-static leyo, ngendlela yayo elula, kubaluleka kubalo lwenani le-code ekhethekileyo kwintsholongwane. Okanye, ngokungaqhelekanga, i-algorithm inokuthi isekelwe kwisimilo, oko kukuthi ukuba le fayili izama ukwenza i-X, Y, Z, ukuyifakela ityala kwaye ikhuphe umsebenzisi kwisigqibo. Ngokuxhomekeke kumthengisi we-antivirus, isayinithi ingathunyelwa njengesignatshi, ifayile yefayile , okanye ifayili ye-DAT .
Isayinwa esisodwa sinokuhambisana nenani elikhulu leentsholongwane. Oku kuvumela i-scanner ukuba ifumane intsholongwane entsha ye-virus engazange ibone ngaphambili. Olu buchule lubizwa ngokubhekiselele kwi-heuristics okanye ukufumanisa okuqhelekileyo. Ukufumanisa okwenziwe ngokuqhelekileyo kungenakusebenza ngokubhekiselele kwiintsholongwane ezintsha kunye nokusebenza ngokuthe xaxa ekufumaneni amalungu amatsha eentsholongwane 'yintsapho' esele yaziwa (iqoqo leentsholongwane ezabelana ngeempawu ezifanayo kunye nezinye iikhowudi enye). Ukukwazi ukubona i-heuristically or generic is important, kuba kuninzi i-scanners ngoku iquka ngaphezu kweenguqu ezingama-250k kunye nenani leentsholongwane ezithe zafunyanwa ziyaqhubeka zikhula ngokukhawuleza ngonyaka emva konyaka.
Iimfuneko zokuphinda zihlaziywe kwakhona
Ngasinye ixesha i-virus entsha itholakale engabonakaliyo ngesignatshana esele ikhona , okanye ingafunyanwa kodwa ayikwazi ukususwa ngokufanelekileyo ngenxa yokuba ukuziphatha kwayo akuhambelani ngokupheleleyo nezinsongo ezaziwa ngaphambili, kufuneka isayinitsha entsha idalwe. Emva kokuba isayinitsha entsha idalwe kwaye ivavanywe ngumthengisi we-antivirus, iqhutywe kumthengi ngendlela yokulungiswa kwemisayina. Ezi zihlaziywa zongeza ubuchule bokufumanisa kwijini injini. Kwezinye iimeko, isayinwa esinikezelwe ngaphambili ingasuswa okanye ithathelwe indawo ngesiginitsha esitsha ukubonelela ngokubhekiselele kumntu wonke okanye ukukhutshwa kwamanzi.
Ngokuxhomekeke kumthengisi wokutyikitya, ukuhlaziywa kunokunikezelwa ngeyure, okanye kwimihla ngemihla, okanye ngezinye iiveki. Ininzi yesidingo sokubonelela isignesha iyahluka kunye nohlobo lwe-scanner, oko kukuthi yintoni na loo khangeli ohlawulwayo ngokufumana. Ngokomzekelo, i-adware kunye ne-spyware ayifani nangoko njengezixhobo ezinjengegciwane, ngoko-ke i-adware / spyware iskena kuphela inokubonelela nge-weekly updates (okanye nangaphantsi kangangoko). Ngakolunye uhlangothi, i- virus scanner kufuneka ibambisane namawaka ezisongelo ezintsha ezifunyenweyo nganye ngenyanga, ngoko ke, ukuhlaziywa kwesayinwa kufuneka kunikwe ubuncinane imihla ngemihla.
Ngokuqinisekileyo, akunakwenzeka ukuba ukhulule isayina ngamnye kwisifo ngasinye esitsha sagqithwe, ngoko ke abathengisi be-antivirus bavame ukukhululwa kwishedyuli esetyenzisiweyo, bafaka yonke i- malware entsha abaye bahlangana nayo ngeli xesha. Ukuba isisongelo esiphezulu okanye esisongelayo sifumaneka phakathi kohlaziyo lwaso oluhleliweyo, abathengisi baya kuhlalutya i-malware, benze iisayinithi, bavavanye, bayikhulule ngaphandle kwebhanti (oko kuthetha ukuba, ukuyikhulula ngaphandle kweshedyuli esiqhelekileyo yokuhlaziya ).
Ukugcina inqanaba eliphezulu lokukhusela, qwasela isofthiwe yakho ye- antivirus ukujonga ukuhlaziywa kaninzi njengoko kuya kuvumela. Ukugcina iisayineli ngokusesikweni akuqinisekisi ukuba intsholongwane entsha ayiyi kukhawuleza, kodwa yenza kube lula kakhulu.
