Emhlabeni we-unqulo wesi arab, isignesha yi-algorithm noma i-hah (inombolo etholakala kulayini wombhalo) okhomba ngokukhethekile igciwane elithile. Kuye ngohlobo lwe-scanner elisetshenziselwa ukusetshenziswa, kungenzeka kube yi-hashi e-static, ewuhlobo olulula kakhulu, inani elibalwe ngenani lekhodi ehlukile yegciwane. Noma, ngokungajwayelekile, i-algorithm ingahle isekelwe ekuziphatheni, okungukuthi uma leli fayela lizama ukwenza i-X, Y, Z, liyifake njengeliyisolisayo futhi livuse umsebenzisi ngesinqumo. Kuncike kumthengisi we-antivirus, isignesha ingathathwa njengesignesha, ifayela lesichasiselo , noma ifayela le-DAT .
Isignesha eyodwa ingase ihambisane nenani elikhulu lamagciwane. Lokhu kuvumela ukuthi isithwebuli sithole igciwane elisha elingakaze libonwe ngaphambili. Leli khono livame ukubizwa ngokuthi i-heuristics noma ukutholakala okujwayelekile. Ukutholakala okujwayelekile kungenakusebenza ngokumelene namagciwane amasha ngokuphelele futhi kuphumelele ngokwengeziwe ekutholeni amalungu amasha 'omndeni' wegciwane esaziwayo (iqoqo lezinambuzane ezabelana ngezici ezifanayo kanye nekhodi efanayo). Ikhono lokuthola i-heuristically noma lemvelo liphawulekayo, njengoba iningi lamaskena manje lifaka ngaphezu kwama-signatures angu-250k futhi inani lamagciwane amasha atholakalayo liyaqhubeka nokwandisa ngonyaka odlule.
Isidingo Esiphindaphindiwe sokuvuselela
Isikhathi ngasinye lapho kutholakala igciwane elisha elingatholakali ngesiginesha esivele likhona , noma lingabonakala kodwa lingasuswa kahle ngoba ukuziphatha kwalo akuhambisani ngokuphelele nezinsongo ezaziwa ngaphambili, isignesha entsha kufanele idalwe. Ngemuva kokuthi isignesha entsha idalwe futhi ihlolwe ngumdayisi we-antivirus, iphelelwe ngaphandle kumakhasimende ngesimo sokubuyekezwa kwesignesha. Lezi zibuyekezo zengeza amandla okuthola enjini yokuskena. Kwezinye izimo, isignesha esinikezwe ngaphambilini ingasuswa noma ishintshwe ngesiginesha esisha ukunikeza ukutholakala okungcono okungcono noma ukukhishwa amandla okucwiliswa.
Kuye kumthengisi wokuskena, izibuyekezo zinganikezwa ngehora ngalinye, noma nsuku zonke, noma ngezinye izikhathi ngisho nangeviki. Isidingo esikhulu sokunikeza amasignesha sihluka ngohlobo lwesithwebuli, okusho ukuthi yini leyo scanner ekhokhwayo ngokuthola. Isibonelo, i-adware ne-spyware ayifuni njengama-viruses, ngakho-ke isithwebuli se-adware / spyware singanikeza kuphela izibuyekezo zesignesha (noma ngisho nangaphansi kancane). Ngakolunye uhlangothi, isithwebuli segciwane kumele sibhekane nezinkulungwane zezingozi ezintsha ezitholakele ngenyanga ngayinye, ngakho-ke, izibuyekezo zesignesha kufanele zinikezwe okungenani nsuku zonke.
Yiqiniso, akunakwenzeka ukukhulula isignesha ngayinye ngegciwane ngalinye elisha elitholiwe, ngakho-ke abathengisi be-antivirus bavame ukukhululwa esimisweni esimisiwe, bahlanganise yonke i- malware entsha abaye bahlangana nayo ngaleso sikhathi. Uma ngabe isongo esivela kakhulu noma esisongelayo sitholakala phakathi kokubuyekezwa okuhleliwe okuhleliwe, abathengisi bayohlola ngokujwayelekile i-malware, benze isignesha, bahlole, futhi bayikhulule ngaphandle kwe-band (okusho ukuthi, ukuyikhulula ngaphandle kwesimiso sabo sokuvuselela esijwayelekile ).
Ukugcina izinga eliphakeme lokuvikela, lungisa isofthiwe yakho ye- antivirus ukuze uhlole izibuyekezo kaningi njengoba kuzovumela. Ukugcina amasignesha asesikhathini akuqinisekisi ukuthi igciwane elisha ngeke lihlehlise, kodwa lenza kube lula kakhulu.
