Isofthiwe ye-antivirus yenzelwe ukuthola, ukuvimbela, nokususa isofthiwe enonya, i-malware. Ukuhlelwa kwe-malware kuhlanganisa amagciwane , izibungu , ama- trojans , ne- scareware , kanye (kuye ngokuthi isithwebuli) ezinye izinhlobo zezinhlelo ezingafuneki (njenge- adware ne-spyware ).
Esikhathini saso, isofthiwe ye-antivirus inikeza ukutholakala kwesignesha esekelwe kwe-malware (isofthiwe enonya). Isiginesha segciwane (aka pattern) sisekelwe engxenyeni eyingqayizivele yekhodi ngaphakathi kwe-malware, evame ukuhlolwa / yokusatshalaliswa ngendlela yesignesha yesignishi (aka pattern) izibuyekezo.
Kusukela ekuqaleni kwawo ngasekupheleni kweminyaka yama-1980, isofthiwe ye-antivirus yashintsha kanye nezinsongo ezikuvikelayo. Ngenxa yalokho, ukutholakala kwesignesha samanje (ukulinganisa iphethini) kuvame ukuqiniswa ngobuchwepheshe obunamandla bokuvimbela ukuziphatha nokusekela.
Isofthiwe ye-antivirus ngokuvamile iyingxoxo yokuphikisana okuphikisanayo. Izingqikithi ezivame kakhulu ezingavumelani phezu kwe-antivirus engakhokhwa mahhala nekhokhelwe, ukucabanga ukuthi ukutatshalaliswa kwesignesha akusizi ngalutho, futhi inkolelo yombango obeka abathengisi be-antivirus ukubhala ama-malware amaskena aklanyelwe ukuthola. Ukulandela kuxoxwa okufushane ngalunye lwalezi zimpikiswano.
I-Versus Fee yamahhala
Isofthiwe ye-antivirus ithungiswa noma isatshalaliswa ngezindlela eziningi, kusuka kubanikidi be-antivirus ngokuzenzakalelayo ukuqedela ama-suites e-intanethi okubopha i- antivirus nge-firewall, izilawuli zobumfihlo, nokuvikeleka kokuvikeleka okunye. Abanye abathengisi, njenge-Microsoft, AVG, Avast, ne-AntiVir banikeza isofthiwe yokuvikela i-antivirus yamahhala yamahhala (ukusetshenziswa kwesinye isikhathi ihhovisi lekhaya elincane).
Ngezikhathi ezithile, izimpikiswano zizoqinisekisa ukuthi i-antivirus yamahhala ingasebenza njenge-antivirus esikhokhelwayo. Ukuhlaziywa kwesikhathi eside kwe-AV-Test.org ukuhlolwa kwesofthiwe ye-antivirus kusikisela ukuthi imikhiqizo ekhokhelwe ivame ukubonisa amazinga aphezulu okuvimbela nokukhishwa kunokuba isofthiwe yamahhala yesilwane samahhala. Ehlangothini lwe-flip, isofthiwe samahhala yesilwane esiphelele sinamahlombe angaphansi kwesici, ngaleyo ndlela idla imithombo yesistimu encane ephakamisa ukuthi ingase isebenze kangcono kuma-computer amadala noma amakhompiyutha anekhono lomsebenzi ongenqunyiwe.
Kungakhathaliseki ukuthi ukhetha i-antivirus yamahhala noma imali esekelwe imali isinqumo somuntu siqu okufanele sisuselwe kumakhono akho wezezimali nezidingo zekhompyutha yakho. Okufanele ukugweme njalo, noma kunjalo, kukhona ama-pop-ups nezikhangiso ezithembisa i-antivirus mahhala. Lezi zikhangiso ziyi-scareware - imikhiqizo enobungozi eyenza izimangalo ezikhohlisayo ukuthi ikhompyutha yakho ifakwe igciwane ukuze ikukhohlise ekuthengeni isithwebuli se-antivirus engalungile.
Amasignesha Awukwazi Ukugcina
Naphezu kokukwazi ukwenza kahle iningi le-malware, i-percentage enkulu ye-malware ingahamba ingatholakali isofthiwe yenkambiso ye-antivirus yendabuko. Ukuze kulungiswe lokhu, indlela yokuphepha ekhethiwe inikeza ukuhlinzekwa okungcono kakhulu, ikakhulukazi uma ukuvikelwa okukhethiwe kuhlinzekwa ngabathengisi abahlukene. Uma konke ukuvikeleka kunikezwa umthengisi oyedwa, indawo yokuhlaselwa iyaba enkulu kakhulu. Ngenxa yalokho, noma yikuphi ukukhathazeka kulesofthiwe yomthengisi - noma ukutholakala okungabanjwanga - kungaba nomthelela omubi kakhulu kunokuba kwenzeke endaweni ehlukile kakhulu.
Noma kunjalo, ngenkathi isofthiwe ye-antivirus ingabambeki-konke okwenziwe yi-malware ngaphandle futhi kunezingxenye ezengeziwe zokuphepha, isofthiwe ye-antivirus kumele ibe yinhloko yimuphi uhlelo lokuvikela olunquma ngalo, njengoba kuyoba yinkinga yokuvimbela iningi lezinsongo okuzofanele ulwe nazo.
I-Antivirus Abadayisi Bhala izigciwane
Ithiyori ye-conspiracy ukuthi abathengisi be-antivirus babhala ama-virus kuyimbono endala, eyisicathulo, futhi engenasisekelo. Ukumangalela kufana nokubiza ukuthi odokotela benza izifo noma amaphoyisa aphanga amabhange ukuze athole ukuphepha emsebenzini.
Kukhona izigidi ze-malware ezingokoqobo, ezingaphezulu kwezinkulungwane ezingamashumi ezinsongo ezisongelwa nsuku zonke. Uma abathengisi be-antivirus babhala i-malware, bekuyoba nomncane kakhulu njengoba kungekho muntu embonini ye-antivirus kuyinto glutton sokujeziswa. Izigebengu nabahlaseli babhala futhi basakaza i-malware. Abasebenzi be-antivirus abathengisi basebenza amahora amaningi futhi anzima ukuqinisekisa ukuthi ikhompiyutha yakho igcinwe ephephile ekubhujisweni. Ukuphela kwendaba.
