Windows Defender Antivirus iz sustava Windows 10 ima nekoliko izvrsnih zaštitnih značajki, od kojih su neke pogrešno shvaćene. Dvije od njih nazivaju se zaštita u oblaku^{(Cloud-delivered protection)} i Automatsko slanje uzorka^{(Automatic sample submission)} i rade u tandemu. Uz njihovu pomoć dobivate učinkovitu zaštitu od nepoznatih prijetnji koje još nisu otkrivene na drugim računalima. Ako ih razmišljate o onemogućavanju ili želite znati što rade kako biste odlučili hoće li ih zadržati omogućenima, pročitajte ovaj članak:

NAPOMENA:^(NOTE:) Značajke podijeljene u ovom članku prvi put su predstavljene u sustavu Windows 10^{(Windows 10)} uz Anniversary Update . Međutim, neke su se stvari promijenile s najnovijim ažuriranjima, pa smo u skladu s tim ažurirali članak.

Što je zaštita u oblaku u sustavu Windows 10^{(Windows 10)} ?

Prema Microsoftu, "approximately 96% of all malware files detected and blocked by Windows Defender Antivirus are observed only once on a single computer, demonstrating the polymorphic and targeted nature of modern attacks, and the fragmented state of the threat landscape. Hence, blocking malware at first sight is a critical protection capability."

Značajka zaštite koja se isporučuje u oblaku iz sustava Windows 10^{(Windows 10)} omogućuje Windows Defender Antivirusu^{(Windows Defender Antivirus)} da na prvi pogled blokira većinu novih, nikad prije viđenih prijetnji. Kada Windows Defender Antivirus treba dodatnu inteligenciju za provjeru namjere sumnjive datoteke, on šalje neke metapodatke usluzi zaštite oblaka koju je stvorio Microsoft , a koja može odrediti je li datoteka sigurna ili zlonamjerna unutar milisekundi.

Kada Windows Defender Antivirus usluga zaštite u oblaku ne može donijeti konačnu presudu, može zatražiti mogući uzorak zlonamjernog softvera za daljnju inspekciju. Ako je omogućeno automatsko slanje uzorka , ^{(Automatic sample submission)}Windows Defender Antivirus prenosi sumnjive datoteke koje pronađe u uslugu zaštite u oblaku radi brze analize. Dok čeka na presudu, Windows Defender Antivirus zaključava te datoteke, sprječavajući moguće zlonamjerno ponašanje. Antivirusni program Windows Defender^{(Windows Defender Antivirus)}zatim poduzima radnje na temelju odluke primljene od usluge zaštite koja se isporučuje u oblaku. Na primjer, ako usluga zaštite u oblaku utvrdi da je datoteka zlonamjerna, ona blokira pokretanje datoteke, pružajući trenutnu zaštitu. Prema zadanim postavkama, Windows Defender Antivirus je postavljen da čeka do 10 sekundi da dobije odgovor od usluge zaštite u oblaku prije nego što pusti sumnjive datoteke da se pokrenu.

Stoga, ako želite da zaštita isporučena u oblaku radi punim potencijalom, značajka automatskog slanja uzorka antivirusnog programa Windows Defender^{(Windows Defender Antivirus)} također bi trebala biti uključena.

Ako želite saznati više pojedinosti o ovoj temi, preporučujemo da pročitate Windows Defender Antivirus usluga zaštite oblaka: Napredna obrana u stvarnom vremenu od dosad neviđenog zlonamjernog softvera^{(Windows Defender Antivirus cloud protection service: Advanced real-time defense against never-before-seen malware)} .

Korak 1. Otvorite aplikaciju Windows Security

Da biste omogućili ili onemogućili zaštitu u oblaku i značajke automatskog slanja uzoraka antivirusnog programa Windows Defender^{(Windows Defender Antivirus)} , prvo što morate učiniti je otvoriti ^{(open the )}aplikaciju ^{( app)}Windows Security . Jedan jednostavan način da to učinite je da kliknete ili dodirnete prečac Windows Sigurnost iz izbornika ^{(Windows Security)}Start^{(Start Menu)} , na popisu aplikacija.

Korak 2. Otvorite postavke zaštite od virusa i prijetnji^(Virus)

U aplikaciji Windows Security kliknite ili dodirnite Zaštita od virusa i prijetnji^{(Virus & threat protection)} .

Pomičite^(Scroll) se prema dolje dok ne pronađete odjeljak pod nazivom "Postavke zaštite od virusa i prijetnji". ^{("Virus & threat protection settings.")}U njemu biste trebali vidjeti vezu pod nazivom "Upravljanje postavkama". ^{("Manage settings.")}Kliknite ili dodirnite na njega.

Korak 3. Omogućite ili onemogućite zaštitu u oblaku i automatsko^(Automatic) slanje uzorka

Na popisu " Postavke zaštite od virusa i prijetnji^{(Virus & threat protection settings)} " pronaći ćete različite prekidače koje možete koristiti za uključivanje i isključivanje različitih zaštitnih značajki Windows Defender Antivirusa^{(Windows Defender Antivirus)} .

"Zaštita koja se isporučuje u oblaku"^{("Cloud-delivered protection")} trebala bi biti uključena prema zadanim postavkama jer "pruža povećanu i bržu zaštitu uz pristup najnovijim zaštitnim podacima u oblaku". ^{("provides increased and faster protection with access to the latest protection data in the cloud.")}Također se navodi da "najbolje radi s uključenim automatskim slanjem uzoraka",^{("works best with Automatic sample submission turned on,")} koji šalje uzorke sumnjivih datoteka Microsoftu^(Microsoft) bez da to učinite. Ako ne želite da Windows Defender Antivirus komunicira s Microsoftovom^(Microsoft) infrastrukturom temeljenom na oblaku i nikada ne prima i šalje podatke iz nje, postavite prekidače za zaštitu u oblaku^{(Cloud-delivered protection)} i za automatsko slanje uzorka^{(Automatic sample submission)} na Isključeno.

Nakon što to učinite, Windows Security kaže da je "Zaštita u oblaku isključena. Vaš uređaj je možda ranjiv"^{("Cloud-delivered protection is off. Your device may be vulnerable,")} i da je "Automatsko slanje uzorka isključeno. Vaš uređaj može biti ranjiv." ^{("Automatical sample submission is off. Your device may be vulnerable.")}Obje su izjave točne i ne preporučujemo onemogućavanje ovih značajki jer one smanjuju učinkovitost antivirusne zaštite koju dobivate u sustavu Windows 10^{(Windows 10)} .

NAPOMENA:^(NOTE:) Ako želite pronaći više pojedinosti o tome koje se informacije šalju Microsoftu^(Microsoft) i kako se koriste, kliknite ili dodirnite vezu "Izjava o privatnosti"^{("Privacy Statement")} koja se nalazi na dnu popisa s postavkama.

Jeste^(Did) li onemogućili zaštitu u oblaku i automatsko^(Automatic) slanje uzorka?

Prije zatvaranja, recite nam jeste li odlučili onemogućiti zaštitu u oblaku^{(Cloud-delivered protection)} i automatsko slanje uzorka^{(Automatic sample submission)} ili ste ih držali uključenima. Komentirajte^(Comment) u nastavku i razgovarajmo.

Should you disable the Cloud-delivered protection from Windows 10?

The Windows Defender Antivirus from Windows 10 has a couple of excellent protection features, some of which are misunderstood. Two of them are named Cloud-delivered protection and Automatic sample submission, and they work in tandem. With their help, you get efficient protection against unknown threats that have not yet been discovered on other computers. If you are considering disabling them, or you want to know what they do to decide whether to keep them enabled, read this article:

NOTE: The features shared in this article were first introduced in Windows 10 with Anniversary Update. However, some things have changed with the latest updates, and we updated the article accordingly.

What is Cloud-delivered protection in Windows 10?

According to Microsoft, "approximately 96% of all malware files detected and blocked by Windows Defender Antivirus are observed only once on a single computer, demonstrating the polymorphic and targeted nature of modern attacks, and the fragmented state of the threat landscape. Hence, blocking malware at first sight is a critical protection capability."

The cloud-delivered protection feature from Windows 10 enables Windows Defender Antivirus to block most new, never-before-seen threats at first sight. When Windows Defender Antivirus needs additional intelligence to verify the intent of a suspicious file, it sends some metadata to the cloud protection service created by Microsoft, which can determine whether the file is safe or malicious within milliseconds.

When the Windows Defender Antivirus cloud-delivered protection service is unable to reach a conclusive verdict, it can request the potential malware sample for further inspection. If Automatic sample submission is enabled, Windows Defender Antivirus uploads the suspicious files that it finds to the cloud protection service, for rapid analysis. While waiting for a verdict, Windows Defender Antivirus maintains a lock on those files, preventing possible malicious behavior. The Windows Defender Antivirus then takes action based on the decision received from the cloud-delivered protection service. For example, if the cloud protection service determines a file as malicious, it blocks the file from running, providing instant protection. By default, Windows Defender Antivirus is set to wait for up to 10 seconds to hear back from the cloud protection service before letting suspicious files run.

Therefore, if you want the cloud-delivered protection to operate at full potential, the automatic sample submission feature of Windows Defender Antivirus should also be turned on.

If you want to learn more details about this topic, we recommend reading Windows Defender Antivirus cloud protection service: Advanced real-time defense against never-before-seen malware.

Step 1. Open the Windows Security app

To enable or disable the cloud-delivered protection and automatic sample submission features of Windows Defender Antivirus, the first thing you have to do is to open the Windows Security app. One easy way to do that is to click or tap on the Windows Security shortcut from the Start Menu, in the list of apps.

Step 2. Open the Virus & threat protection settings

In the Windows Security app, click or tap Virus & threat protection.

Scroll down until you find the section called "Virus & threat protection settings." In it, you should see a link called "Manage settings." Click or tap on it.

Step 3. Enable or disable Cloud-delivered protection and Automatic sample submission

In the list of "Virus & threat protection settings," you find different switches that you can use to turn on and off the various protection features of Windows Defender Antivirus.

The "Cloud-delivered protection" should be turned on by default because it "provides increased and faster protection with access to the latest protection data in the cloud." It also states that it "works best with Automatic sample submission turned on," which sends samples of suspicious files to Microsoft without prompting you to do so. If you do not want Windows Defender Antivirus to communicate with Microsoft's cloud-based infrastructure, and never receive and send data from it, set the switches for Cloud-delivered protection and for Automatic sample submission to Off.

After you do that, Windows Security says that "Cloud-delivered protection is off. Your device may be vulnerable," and that "Automatical sample submission is off. Your device may be vulnerable." Both statements are correct, and we do not recommend disabling these features, as they lower the effectiveness of the antivirus protection that you get in Windows 10.

NOTE: If you want to find more details about what information is sent to Microsoft and how it is used, click or tap the "Privacy Statement" link found at the bottom of the list with settings.

Did you disable the Cloud-delivered protection and Automatic sample submission?

We hope that this guide has helped you better understand these protection features included in Windows 10, and Windows Defender Antivirus. Before closing, tell us whether you decided to disable Cloud-delivered protection and Automatic sample submission or whether you kept them turned on. Comment below and let's discuss.
