Anti - yog dab tsi no? tswv yim

Antivirus paub rau ib ntev lub sij hawm. Tej kev pab cuam tau hnov kiag li txhua leej txhua tus, txawm nyob deb los ntawm lub computer technology. Nyob rau hauv hauv paus ntsiab lus, yog hais tias peb tham nyob rau hauv nqe lus dav dav, tus anti-virus - qhov no yog qhov tseem ceeb rau kev totaub txog cov kev ruaj ntseg ntawm tag nrho cov computer system thiab cov ntaub ntawv kev ncaj ncees.

Yuav ua li cas yog antivirus software? General tswv yim

Yog hais tias peb tham txog dab tsi yog qhov anti-virus software, ces, roughly hais lus, yog ib tug hluas daim ntawv thov los yog ib tug txheej ntawm software cuab yeej uas yog tsim los tiv thaiv systems thiab cov ntaub ntawv los ntawm malware kev tshawb fawb thiab nrhiav kom tau ntawm cov kab mob, tshem tawm lawv cov los yog kev kho mob ntawm tus kab mob yam nyob rau hauv ib tug system cov ntaub ntawv los yog ntsia daim ntaub ntawv.

Yog li, peb yuav hais tias anti-virus - qhov no software muab ua kom tiav kev tiv thaiv rau computer systems los ntawm lwm hem hais tias yuav nkag mus rau nws los ntawm hauv Internet, los ntawm e-mail los yog siv tshem tawm.

kev faib antivirus

Nrog hais txog kev faib tawm, anti-virus software yuav tsum tau muab faib raws li lub hom phiaj thiab cov hom kev kawm ntawm tus tsom xam, tsis hais qhov kev khiav hauj lwm systems nyob rau hauv tej kev kawm uas yuav tsum ntawm lawv hauj lwm.

Nyob rau hauv cov nqe lus ntawm destinations, antivirus - nws yog yog ib tug pab cuam rau kev tsom xam, qhia thiab tshem tawm cov siab phem code los yog daim ntaub ntawv, los yog tag nrho software pob uas yuav tsis tsuas tau cov saum toj no cov kauj ruam, tab sis kuj pab qhia ntawv rau kev tiv thaiv nyob rau hauv cov nqe lus ntawm kev ua hauj lwm nyob rau hauv lub Web site, xa thiab tau txais e-mail tiv thaiv tawm tsam spyware uas tau nyiag cov ntaub ntawv nyob rau hauv lub keeb kwm yav dhau thaum tus neeg siv tsis tau txawm twb paub lawm, thiab lwm yam (Lub thiaj li hu ua version ntawm antivirus software).

Qhov yooj yim piv txwv yog lub ob software khoom hom Eset NOD32 thiab Eset ntse Security.

Qhov thib ob pob muaj ntau txoj kev xaiv thiab yuav tsis tsuas kam nrog kev txiav txim muaj nyob rau hauv lub system ntawm cov kab mob, tshem tawm lawv, thiab kho cov seem cov ntaub ntawv. Muaj yog ib tug ncaj haib nta txawm rau kev tiv thaiv ntawm lub computer systems thiab cov ntaub ntawv rau ib qhov kev twb kev txuas rau Internet, thiab txawm software muaj nuj nqi ntawm "proactive" muaj txuj ci, muaj peev xwm los tsim ib tug backup los, yuav encrypt cov ntaub ntawv thiab ntau npaum li cas.

Ib qho tseem ceeb qhov chaw nyob rau hauv lub cais ntawm xws software nyob thiab txoj kev tsom xam. Lawv muab faib ua ib tug kos npe rau thiab probabilistic.

kos npe tsom xam

Kos npe txoj kev yog raws li nyob rau hauv lub fact tias anti-virus software piv cov qauv ntawm cov tej yam txawv cov ntaub ntawv nrog cov neeg uas muab cia rau hauv lub kos npe rau database. Uas yog vim li cas peb yuav hais tias antivirus - yog ib daim ntawv uas yuav tsum tau tas li muab kho dua. Raws li yog qhov tseeb, qhov no vib this tsis muab ib tug 100 feem pua guarantee ntawm kev ruaj ntseg, vim hais tias cov kev pab cuam muaj peev xwm mus qhia tau tsuas paub tias cov kab mob. Ntawm cov yooj yim tshaj plaws kev pab cuam ntawm no hom yuav tsum tau qhia, "Avast" - anti-virus, uas yog pub dawb.

probabilistic tsom xam

Raws li rau lub tsom xam ntawm no hom, nws yog muab faib ua heuristic, tus cwj pwm thiab sib piv ntsuam checksums.

Nyob rau hauv luv luv, nyob rau hauv cov nqe lus ntawm heuristics antivirus - nws txhais tau hais tias cov ntaub ntawv cov qauv rau lub hauv paus ntawm ib tug sib piv ntawm cov paub kab mob, raws li tau zoo raws li paub algorithms uas lawv siv nyob rau hauv lawv cov chaw ua hauj lwm.

Tus cwj pwm coj tsom xam implies qhov yuav tshwm ntawm kev ua tau tej yam. Feem ntau nws yog hais txog executable macros, scripts los yog applets. Nyob rau hauv lwm yam lus, cov txheej txheem no yeej muaj peev xwm mus twv seb yog dab tsi txiav txim tej zaum yuav tiav nyob rau hauv ib co tej yam txawv cov ntaub ntawv los yog daim ntawv thov.

Piv checksums - nws yog ib txoj kev nyob rau hauv uas lub checksums ntawm cov ntaub ntawv khaws tseg nyob rau hauv lub cache, thiab ces piv nrog tom ntej tseem ceeb. Qhov xaus hais tias cov muaj ib tug kev hem thawj yuav tsum ua nyob rau hauv lub hauv paus ntawm dab tsi yog ua nyob rau tib lub sij hawm los yog ib tug loj heev kev hloov ntawm system khoom.

Raws li yog qhov tseeb, yuav luag tag nrho txoj kev muaj heev zwj ceeb kev txiav txim ntawm lub xub ntiag ntawm tus kab mob no. Piv txwv li, "Avast" - anti-virus, uas yuav tsum noj raws li ib tug kev hem thawj rau lub tua ntawm tej macro commands, thaum ua tau ib tug kab mob los yog siab phem code nws tsis yog. Txhua txoj kev kwv yees qhov tshwm sim ntawm kev hem thawj nws muaj nws pluses thiab minuses. Tab sis lawv ua ke nyob rau hauv ib yam khoom uas muab ib tug ntau tangible tau, uas koj mus qhia kab mob, malware los yog spyware rau lub hauv paus ntawm cumulative tsom xam.

Qhov tseem zoo-paub anti-virus software

Raws li rau lub anti-virus software, hnub no computer technology nyob rau hauv lub ntiaj teb no muaj ib tug ntau ntawm tej yam yooj yim daim ntawv sau npe thiab ntawm tag nrho mixed-siv ceg. Tej zaum cov feem ntau zoo-paub software pob yuav hu ua "Kaspersky Anti-Tus kab mob no", uas muaj nyob deb ntawm cov loj tshaj plaws lub sij hawm muab piv rau tag nrho lwm cov khoom.

Txawm li cas los, qhov no pob yog tsim los rau haib txaus nyob rau hauv cov nqe lus ntawm system ua tau zoo, vim hais tias nws muab xws li ib tug load nyob rau hauv lub active hom, muaj hwj huam computers thiab laptops tsuas "poob dej tuag" nyob rau hauv lub lag luam. Txawm li cas los, cov "Kaspersky Anti-Tus kab mob no" nws muaj nws yam tsawg kawg nkaus thiab pom zoo uas yuav tsum rau lub computer "hlau". Yog li ntawd nws yog tsis tau rau txhua computer rau nruab.

Tsis pub tsawg nrov thiab cov khoom Corp. Eset. Ntawm no, feem ntau nrov yog system Eset NOD32 thiab Eset ntse Security, uas tau hais saum toj no. Nws yuav tsum tau muab sau tseg tias cov khoom "Kaspersky Lab" thiab lub tuam txhab Eset them los yog shareware, yog li ntawd ib puag ncig sum rau lawv yuav muaj rau nteg tawm (ntawm chav kawm, kev kawm rau kev siv ntawm daim ntawv tso cai software). Nws mus tsis tau hais tias cov Internet yuav nrhiav tau thiab "kreknutye" version. Ntawm no yog cov cia li ib tug guarantee ntawm tag nrho cov functionality yuav tsis muab txawm lub crackers lawv tus kheej.

Ntawm cov dawb cov kev pab cuam ntau cov neeg siv xav tib yam Avast, antivirus Panda, lub AVG, McAffee, lub Norton Antivirus, etc. Nyob rau hauv qhov tseeb, anti-virus software yog tam sim no heev heev, yog li ntawd txhua tus neeg xaiv ib yam dab tsi ua hauj lwm nrog thiab yuav ua li cas los tiv thaiv lub system.

xaus

Tej zaum neeg feem coob tau pom tau hais tias cov anti-virus - ib qho kev pab rau kom tiav kev tiv thaiv tsis tau tsuas yog los ntawm cov kab mob, tab sis kuj los ntawm ib tug ntau yam ntawm sab nraud ntshai heev txawm hais txog espionage los yog cov tub sab tub nyiag ntawm ntaub ntawv, nyob rau hauv Feem ntau, ntawm tej yam uas yuav ua rau ib tug kev hem thawj rau lub operating system , "hlau" (muaj ib co kab mob) thiab cov neeg siv cov ntaub ntawv khaws tseg rau lub hard drive, tshem tawm, los yog txawm nyob rau hauv lub "huab" cia.
