Markaan dhex maraayo golayaasha waxa aan inta badan helaa su'aashan la iswaydiiyay marar badan - Ma awoodo in aan gacanta u shido Windows Defender ama Windows Defender ma dami doono ama ma dami doono oo ma bilaabi doono Windows 11 , Windows 10, Windows 8, ama Windows 7. Haddii aad la kulanto arrintan, markaa qoraalkan ayaa ku caawin kara.

Ma daari karo Windows Defender gudaha Windows 11/10

Haddii aadan awoodin inaad bilowdo Windows Defender , markaa mid ka mid ah talooyinkan ayaa hubaal ah inay ku caawiyaan:

1. Hubi haddii aad ku rakiban tahay software kale oo ammaan ah
2. Ka hubi taariikhda ama wakhtiga PC gaaga
3. Ku socodsii Windows Update
4. Hubi goobaha Aagga Internetka
5. Hubi dejinta Siyaasadda Kooxda
6. Hubi goobta diiwaanka
7. Hubi heerka Adeegga
8. Ku sawir PC software ka-hortagga la qaadi karo
9. Hubi qiimaha AllowUserUIAccess .

Aan si faahfaahsan u aragno talooyinka.

1] Hubi^(Check) haddii aad haysato software kale oo ammaan ah oo lagu rakibay

Mid ka mid ah dabeecadaha ugu caansan ee Difaaca Windows^{(Windows Defender)} waa haddii ay ogaato software-ka-ka-hortagga koox saddexaad, markaa Windows Defender wuu is-xiri doonaa. Daaqadaha^(Windows) waxaa loogu talagalay in lagu ogaado joogitaanka software-ka amniga ee lagu rakibay, waxaana inta badan aan aragnaa ogeysiinta Xarunta Waxqabadka^{(Action Center)} . Mid ka mid ah arrimaha caadiga ah ee aan horay u soo aragnay waa marka ay jiraan barnaamijyo badan oo amniga ah oo lagu rakibay. Waxay inta badan abuurtaa khilaaf dhexdooda ah oo aakhirka, waxay abuurtaa dhibaato ka badan intii wanaag la samayn lahaa. Qabow soo noqnoqda, ku dhaca codsiyada waa qaar ka mid ah arrimaha caadiga ah ee dhaca marka aad rakibto wax ka badan hal software ka-hortagga.

Markaa si looga fogaado xaaladdan, Difaaca Windows^{(Windows Defender)} wuu is dami doonaa marka uu ogaado barnaamij kale oo ammaan ah. Sidoo kale^(Likewise) , haddii codsigan ammaanku leeyahay Firewall , markaa Windows Firewall sidoo kale wuu joojin doonaa shaqada. Markaa haddii aad rabto in  Windows Defender uu shaqeeyo, waa inaad uninstall-ka ka saartaa software-kaaga amniga ee qolo saddexaad oo aad dib u bilowdo nidaamka.

Inta badan^(Often) isticmaalayaashu waxay ogaan karaan haddii software ammaanku runtii rakiban yahay iyo haddii kale sababtoo ah markaad iibsanayso laptop cusub, badanaa waxay la socotaa nooca tijaabada ah ee software amniga sida Norton , McAfee , iwm. Kadib markaad rakibto codsiyada sida Flash ama Java , waxaa laga yaabaa in ay ku jirto. ku sheeg in aad uninstall-ka ka saarto iskaanka amniga ee bilaashka ah marka badankoodu aanay ogaan. Markaa waxa fiican in aad baadho kombayutarkaga haddii aanad hubin in software ammaanku rakiban yahay iyo in kale. Marka laga saaro waxa laga yaabaa inaad u baahato inaad gacanta dib ugu shido.

Ku qor " Daacadaha Windows^{(Windows Defender)} " sanduuqa raadinta ka dibna tabo Gelida^(Enter) . Guji ^(Click) Settings oo hubi inay jirto calaamad muujinaysa Daar ilaalinta waqtiga-dhabta ah talada^{(Turn on real-time protection recommend)} .

On Windows 10 , fur Windows Security > Virus Ilaalinta Virus-ka oo u beddel ilaalinta waqtiga-dhabta ah^{(Real-Time Protection)} booska.

2] Ka hubi^(Check) taariikhda ama wakhtiga PC gaaga

Arrinka kale ee u keeni kara Windows Defender in aanu si sax ah u shaqayn waa taariikhda ama wakhtiga khaldan ee mashiinka Windows -kaaga. ^(Windows)Hubi inaad u dejisay saacada Windows-gaaga iyo taariikhdaada si sax ah loo dejiyay ka dibna isku day inaad dib u shido Difaaca Windows^{(Windows Defender)} oo arag inay si fiican u shaqaynayso. Waa yaab, laakiin inta badan nidaamka hawlgalka Windows shaqeeyaan, ku salaysan taariikhda iyo wakhtiga nidaamka. Markaa taariikh ama waqti khaldan waxay kicin kartaa dabeecad aan caadi ahayn Windows OS kaaga .

3] Ku socodsii Windows Update

Waxyaabaha kale ee muhiimka ah ee keeni kara arrimaha waa, haddii aadan Windows -ka la soconin, marka loo eego Windows Update . Tani waxay sababi kartaa arrimo ku saabsan Difaaca Windows^{(Windows Defender)} ama barnaamij kasta oo kale oo Windows ah. Marka ay timaado software kasta oo amniga ah, waxay had iyo jeer u baahan tahay saxiixyadii ugu dambeeyay iyo cusboonaysiinta kale ee asaasiga ah ee Windows si aad u ilaaliso kombayutarkaga. Markaa waxaan aad ugu talin lahaa in la socodsiiyo Cusboonaysiinta Windows^{(Windows Update)} oo dhammaystiran , ka dibna gal Windows Defender oo sidoo kale ka socodsii wax cusboonaysiin ah halkaas. Ka dib eeg haddii Difaacahaaga Windows^{(Windows Defender)} uu si fiican u shaqeeyo.

4] Hubi goobaha Aagga Internetka

Dhacdooyinka kor laga wada hadlay ayaa ah kuwa ugu badan. Marka laga reebo kuwan, waxaa jiri kara arrimo yaryar oo saameyn kara shaqada Windows Defender . Waxay noqon kartaa goob aan sax ahayn oo^(Zone) ku taal Internet Explorer , taas oo aad ku hagaajin karto dib u dejinta Internet Explorer ee goobaha warshadda. Mar labaad^(Again) , haddii aad isticmaalayso server^(Proxy) -ka wakiil , Windows Defender ma awoodi doono inuu cusbooneysiiyo.

Xaaladahan oo kale, waxaad u baahan tahay inaad isbeddel yar ku samayso server- kaaga wakiilnimada .^(Proxy)

Riix Windows + X oo dooro Command Prompt (Admin)

Ku qor kan soo socda oo ku dhufo Enter:

NETSH WINHTTP SET PROXY 1.1.1.1:8080 or NETSH WINHTTP SET PROXY MYPROXY.NET:8080

Hadda dib u bilow nidaamka oo arag haddii uu shaqeeyo.

5] Hubi dejinta Siyaasadda Kooxda

Fur tifaftiraha Siyaasadda Kooxda oo u gudub goobta soo socota:

Computer Configuration > Administrative Template > Windows Components > Windows Defender Antivirus.

Geli shayga^(SIn) saxda ah, laba-guji Demi ^(Turn)Difaaca Difaaca Windows^{(Windows Defender Antivirus)} .

Marka xigta, dooro Not Configured , dhagsii badhanka Codso^(Apply) iyo OK.

6] Hubi goobta diiwaangelinta

Fur Registry Editor oo u gudub goobta soo socota:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

Hel DisableAntiSpyware furaha. Haddii furahani aanu joogin, samee qiime cusub iyo DWORD (32-bit) .

Deji xogteeda qiimaha 0 oo ka bax.

7] Hubi heerka Adeegga

Ku socodsii services.msc si aad u furto Maareeyaha Adeegyada^{(open Services Manager)} . Hubi in adeegga Difaaca Windows^{(Windows Defender service)} uu bilaabmay oo loo dejiyay Toomaatig ah.

8] Ku baadh PC software ka-hortagga la qaadi karo

Ugu dambeyntii, waxay noqon kartaa malware-ka laftiisa kaas oo keenaya in Difaaca Windows^{(Windows Defender)} uusan si sax ah u shaqeyn. Waxaad soo dejisan kartaa oo aad isticmaali kartaa Qalabka Khadka Tooska ah ee Difaaca Windows ama barnaamij kasta oo kale oo ka hortag ah^{(standalone antivirus software)} oo aad sameyso iskaan dhammaystiran.

9] Hubi qiimaha AllowUserUIAccess

Haddii ay hoos yimaadaan Settings Security Windows^{(Windows Security)} , ikhtiyaarka " Fayraska & ilaalinta khatarta^{(Virus & threat protection)} " waa la waayay, ka dib Andrew wuxuu soo jeedinayaa kuwan soo socda:

Ku socodsii tafatiraha Registry ^{(Run Registry Editor)}maamule^{(Administrator)} ahaan oo tag:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\Policy Manager

Deji qiimaha AllowUserUIAcess ^{(AllowUserUIAccess)}1 .

Kuwani waa qaar ka mid ah sababaha caadiga ah sababta Windows Defender uusan u bilaabin.

PS : Difaaca Windows waa dansan yahay ama ma shaqaynayo^{(Windows Defender is turned off or not working)} waxa uu  bixiyaa talobixin cilad-baadhiseed oo dheeraad ah, kaas oo waliba ku xiisaynaya.

Waxa kale oo laga yaabaa inaad rabto inaad hubiso qoraalladan ka caawiya xallinta dhibaatooyinka Difaaca Windows:^{(You may also want to check out these posts which help troubleshoot Windows Defender problems:)}

Can't turn on Windows Defender in Windows 11/10

When I browse through forums I often find this question asked many tіmеs – I am unable to turn on Windows Defender manually or Windows Defender won’t or will not turn on and start in Windows 11, Windows 10, Windows 8, or Windows 7. If you face this issue, then this post may help you.

Can’t turn on Windows Defender in Windows 11/10

If you are unable to start Windows Defender, then one of these suggestions is sure to help you:

1. Check if you have another security software installed
2. Check the date or time on your PC
3. Run Windows Update
4. Check Internet Zone settings
5. Check Group Policy setting
6. Check Registry setting
7. Check the status of Service
8. Scan PC with portable antivirus software
9. Check the value of AllowUserUIAccess.

Let us see the suggestions in detail.

1] Check if you have another security software installed

One of the most common behaviors of Windows Defender is that if it detects a third-party antivirus software, then Windows Defender will shut itself off. Windows is designed to detect the presence of security software installed, and we often get to see the notification in the Action Center. One of the common issues we have seen in the past is when there are multiple security software installed. It often creates a conflict between them and in the end, it creates more trouble than doing any good. Frequent freezing, crashing to applications are some of the common issues which occur when you install more than one antivirus software.

So to avoid this situation, Windows Defender will turn itself off when it detects another security program. Likewise, if this security application has a Firewall, then Windows Firewall will also stop working. So in case you want Windows Defender to work, then you will have to uninstall your third-party security software and reboot the system.

Often users may be unaware if security software is indeed installed or not because when you buy a new laptop, mostly it comes with a trial version of security software like Norton, McAfee, etc. Then when you install applications like Flash or Java, it might prompt you to uninstall free security scanner when most of them don’t notice. So it’s best to search your PC if you’re not sure if security software is installed or not. Once it’ removed you may need to turn it manually back on.

Type “Windows Defender” in the search box and then press Enter. Click Settings and make sure there is a checkmark on Turn on real-time protection recommend.

On Windows 10, open Windows Security > Virus protection and toggle the Real-Time Protection switch to On position.

2] Check the date or time on your PC

The other issue that could cause Windows Defender not to work properly is the incorrect date or time on your Windows machine. Make sure you have set your Windows clock & date set properly and then try to turn your Windows Defender back on and see if it works fine. It’s strange, but most of the Windows operating system functions work, based on the system date and time. So an incorrect date or time could trigger abnormal behavior in your Windows OS.

3] Run Windows Update

Another important thing that could cause issues is, if you Windows is not up to date, in terms of Windows Update. This could cause issues in Windows Defender or any other Windows core application. When it comes to any security software, it always needs the latest signature updates and other Windows core updates to keep your PC secure. So I would highly recommend running a complete Windows Update, then go into Windows Defender and run an update from there as well. Then see if your Windows Defender is working fine.

4] Check Internet Zone settings

The above-discussed scenarios are the most common ones. Apart from these, there could be some minor issues that could affect the working of Windows Defender. It could be an incorrect Zone setting in Internet Explorer, which you can fix by resetting Internet Explorer to factory settings. Again, if you are using a Proxy server, Windows Defender will not be able to update.

In such cases, you need to make some small changes to your Proxy server.

Press Windows + X and select Command Prompt (Admin)

Type in the following and hit Enter:

NETSH WINHTTP SET PROXY 1.1.1.1:8080 or NETSH WINHTTP SET PROXY MYPROXY.NET:8080

Now reboot the system and see if it works.

5] Check Group Policy setting

Open Group Policy Editor and navigate to the following setting:

Computer Configuration > Administrative Template > Windows Components > Windows Defender Antivirus.

SIn the right pane, double-click on Turn off Windows Defender Antivirus.

Next, select Not Configured, click the Apply and OK button.

6] Check Registry setting

Open Registry Editor and navigate to the following setting:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

Locate DisableAntiSpyware key. If this key is not present, create a new and DWORD (32-bit) Value.

Set its Value data to 0 and exit.

7] Check the status of Service

Run services.msc to open Services Manager. Ensure that the Windows Defender service is started and set to Automatic.

8] Scan PC with portable antivirus software

Finally, it could be a malware itself that’s causing Windows Defender not to work properly. You could download and use Windows Defender Offline Tool or any other standalone antivirus software and run a complete scan.

9] Check value of AllowUserUIAccess

If under Windows Security settings, the option for “Virus & threat protection” has disappeared, then Andrew suggests the following:

Run Registry Editor as Administrator and go to:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\Policy Manager

Set value of AllowUserUIAccess to 1.

These are some common reasons why Windows Defender does not start.

PS: Windows Defender is turned off or not working offers some additional troubleshooting suggestions, which may also interest you.
