Pansipa tilembere mitundu isanu ndi iwiri yowopsa yamavuto apakompyuta yomwe muyenera kumvera
1- Vuto la Makina a Boot
Malinga ndi momwe wogwiritsa ntchito amagwiritsira ntchito, mavairasi a Boot Sector ndi ena mwa owopsa kwambiri. Chifukwa zimakhudza mbiri ya boot, ndizovuta kuchotsa, ndipo mtundu uwu wama virus umalowerera m'magulu azokha pulogalamu ya boot pa disk, kuwononga ndikusokoneza zomwe zili mkati, zomwe zimabweretsa kulephera kwa boot process.

2- Direct Action Virus - Direct Action Virus
Direct action virus ndiimodzi mwamagawo akulu awiri a ma virus omwe samadzitsimikizira okha kapena amphamvu ndipo amakhala obisika m'makompyuta.
Tizilombo toyambitsa matendawa timagwira mwa kudziphatika ku mtundu winawake wa mafayilo - mafayilo a EXE kapena - COM.Nthawi zambiri munthu wina akatulutsa fayiloyo, fayiloyo imakhala yamoyo, kufunafuna mafayilo ena ofananawo mukakalembedwe mpaka ikamafalikira mwankhanza.
Kumbali yabwino, kachilomboka nthawi zambiri sikachotsa mafayilo ndipo sikulepheretsa magwiridwe antchito anu ndikulepheretsa mafayilo ena omwe sangathe kufikako.
3- Virus Wokhala
Mosiyana ndi ma virus achindunji, mavairasi omwe amakhalawa ndiowopsa ndipo amaikidwa pakompyuta ndipo amaloledwa kugwira ntchito ngakhale gwero loyambilira la matenda litachotsedwa. Mwakutero, akatswiri amawawona kuti ndi owopsa kuposa msuwani wawo kachilombo koyambitsa matenda omwe tidatchulapo kale.
Kutengera pulogalamu yamatendawa, pulogalamuyi imatha kukhala yovuta kuzindikira komanso kuvuta kwambiri. Mavairasi okhalamo akhoza kugawidwa m'magulu awiri: ma vekitala othamanga komanso ma vekitala ochedwa. Zonyamula mwachangu zimawononga kwambiri mwachangu motero ndizosavuta kuzizindikira, pomwe zonyamula pang'onopang'ono zimavuta kuzizindikira chifukwa zizindikiro zawo zimayamba pang'onopang'ono.
Pazovuta kwambiri, atha kuvulaza antivayirasi anu, ndikupatsira mafayilo aliwonse omwe pulogalamuyo imawunika. Nthawi zambiri mumafunikira chida chapadera - monga chida chogwiritsira ntchito - kuti muchotseretu kachilombo koyambitsa matendawa kotero kuti kugwiritsa ntchito pulogalamu yaumbanda sikungakutetezeni.
4- Ma virus angapo

Tizilombo toyambitsa matendawa titha kufalikira m'njira zingapo, ndipo titha kutenga zochitika zosiyanasiyana pamakompyuta omwe ali ndi kachilombo kutengera mitundu, monga makina oikidwiratu kapena kupezeka kwa mafayilo ena.
Itha kupatsira gawo la boot ndi mafayilo omwe ikwaniritsidwa, kuwalola kuti ichitepo kanthu mwachangu ndikufalikira mwachangu.
Kwenikweni ndizovuta kuchotsa. Ngakhale mutayeretsa mafayilo amtundu wa chipangizocho, ngati kachilomboka katsalabe mu gawo la boot, mwatsoka nthawi yomweyo komanso mosasamala kadzaberekanso mukadzatsegulanso kompyuta.
5- Kachilombo ka Polymorphic
Malinga ndi Symantec, wopanga mapulogalamu apakompyuta padziko lonse lapansi, ma virus a polymorphic ndi amodzi mwa ma virus owopsa omwe ndi ovuta kuwazindikira kapena kuwachotsa ndi mapulogalamu a antivirus. Kampaniyo imati makampani oletsa mavairasi amafunika "kuthera masiku kapena miyezi kuti apange njira zolondola zojambulira."
Koma ndichifukwa chiyani kuli kovuta kuthana ndi ma virus a polymorphic? Umboniwo uli m'dzina lake lenileni. Mapulogalamu a antivirus amatha kulembetsa mtundu umodzi wa ma viruswa, koma virus ya polymorphic imasinthira siginecha (kanema kake) nthawi iliyonse ikabwereza, ndipo pulogalamu ya antivirus imatha kupenga chifukwa ma virus a polymorphic amatha kuzemba mosavuta kuchokera pamndandanda wakuda.

Vuto lolemba ndi amodzi mwamatenda okhumudwitsa kunja uko, ngakhale atakhala kuti siowopsa pamakina anu onse.
Izi ndichifukwa choti chimachotsa zomwe zili mufayilo iliyonse, njira yokhayo yochotsera kachilomboko ndikuchotsa fayiloyo, chifukwa chake mutha kuchotsa zonse zomwe zili mkatimo ndipo zitha kupatsira mafayilo oyimirira okha ndi pulogalamu yonse .
Nthawi zambiri ma virus amtundu amabisika ndikufalikira kudzera pa imelo, zomwe zimawapangitsa kukhala kovuta kuzindikira kwa ogwiritsa ntchito makompyuta ambiri.

Njirayi imalola kuti pulogalamuyi itenge kachilombo popanda kuwononga kachidindo kapenanso kuwonjezera kukula kwake, ndikupangitsa kuti izitha kudutsa ma antiviruses mu njira zowabisira zomwe ma virus ena amadalira.
Mwamwayi, mtundu uwu wa kachilombo ndi wosowa, ngakhale kukula kwa mawindo otsogolera a Windows akuwapatsa mwayi watsopano wa moyo.
