Kada je hardver ili softver instaliran i ne dolazi s digitalno potpisanom datotekom, to izaziva sumnju na bilo kakav antivirus i sam Windows . Poznato je da Windows Security^{(Windows Security)} , aka Windows Defender , ispušta pogrešku 577^{(Error 577)} kada ne može provjeriti digitalni potpis u takvoj situaciji. Ovaj će vam post pomoći riješiti problem.

Windows nije mogao pokrenuti uslugu Windows Defender^{(Windows Defender Service)}

Cijela poruka o pogrešci je sljedeća:

Windows could not start Windows Defender Service.

Error 577: Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that was signed incorrectly or damaged, or that might be malicious software from an unknown source.

Pogreška Windows Defendera 577^{(Defender Error 577)} , Nije moguće provjeriti digitalni potpis

Pogreška se obično javlja kada uključite Windows Defender i tada dolazi do sukoba s postojećim softverom. Nije samo bilo koji softver, već sigurnosni softver koji može uzrokovati problem.

1] Provjerite postoji li preostali softver

Ako ste instalirali novi Antivirus ili ste nedavno deinstalirali softver, moguće je da je iza sebe ostavio neke datoteke, a deinstalacija nije dovršena. Morat ćete ručno potražiti datoteke ili locirati program za deinstalaciju da bi ga program izbrisao. Ako je riječ o sigurnosnom softveru, upotrijebite ove alate za uklanjanje virusa^{(AntiVirus Removal Tools)} . Ako nije na popisu, možete isprobati besplatni softver za deinstalaciju^{(free uninstaller software)} za brisanje preostalih datoteka.

2] Provjerite deinstalaciju Webroot-a

Ako ste koristili Webroot , možda se nije deinstalirao u potpunosti i ispravno. Upotrijebite ovaj alat iz Webroot^{(tool from Webroot)} -a da dovršite deinstalaciju i vidite hoće li pomoći.

3] Uključite Windows Defender

Imamo iscrpan post o različitim načinima na koje možete slijediti kada ne možete uključiti Windows Defender. ^{(cannot turn on Windows Defender.)}Ako vam odgovara Registry , slijedite ove korake da biste uključili Windows Defender .

Pritisnite tipku Win^{(Press Win)} + R da otvorite prompt za pokretanje .^(Run)

Upišite “^{(Type “)} regedit” i pritisnite tipku Enter

Dođite do ovih tipki:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender

Promijenite vrijednost ' DisableAntiSpyware ' i ' DisableAntiVirus ' iz '0' u ' 1 '.

Ako ga nema, možete stvoriti DWORD s istim nazivima i promijeniti vrijednost.

Pokušajte ponovno pokrenuti Windows Defender i trebao bi raditi.

Nadam se da je objavu bilo lako pratiti i da ste uspjeli uključiti Windows Defender i riješiti problem s pogreškom 577^{(Error 577)} . Iako posljednja metoda dobro funkcionira, imajte na umu da se morate riješiti bilo koje probne verzije sigurnosnog softvera ili preostalog registra i datoteka da biste to konačno riješili.

Windows Defender Error 577, Cannot verify the digital signature

When a hardware or software is installed and does not comе with a digitally signеd file, it raises a suѕpicion of any Antivirus and Windоws itself. Windows Security, aka Windows Defender, has been known to throw Error 577 when it cannot verify the digital signature in such a situation. This post will help you resolve the problem.

Windows could not start Windows Defender Service

The full error message is as follows:

Windows could not start Windows Defender Service.

Error 577: Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that was signed incorrectly or damaged, or that might be malicious software from an unknown source.

Windows Defender Error 577, Cannot verify the digital signature

The error usually occurs when you turn on Windows Defender, and that’s when the conflict happens with existing software. It’s not just any software, but security software that may be causing the problem.

1] Check for Residual Software

If you had installed a new Antivirus or recently uninstalled a software, then it is possible that it has left some files behind, and the uninstallation is incomplete. You will have to manually look around for files or locate an uninstaller for the program to delete it. If it is security software, then use these AntiVirus Removal Tools. If it is not on the list, you can try a free uninstaller software to delete residual files.

2] Check Webroot uninstallation

If you have used Webroot, it may not have uninstalled fully and properly. Use this tool from Webroot to complete the uninstallation and see if it helps.

3] Turn on Windows Defender

We have an exhaustive post on different ways you can follow when you cannot turn on Windows Defender. If you are comfortable with Registry, then follow these steps to turn on Windows Defender.

Press Win key + R to open Run prompt.

Type “regedit” and press the Enter key

Navigate to these keys:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender

Change value of ‘DisableAntiSpyware‘ and ‘DisableAntiVirus‘ from ‘0’ to ‘1‘.

If it is not there, you can create the DWORD with the same names and change the value.

Try re-running the Windows Defender, and it should work.

I hope the post was easy to follow, and you were able to turn on the Windows Defender and resolve the Error 577 problem. While the last method works fine, be aware that you need to get rid of any trial version of security software or leftover registry and files to resolve it finally.
