1.電源ボタンを押し続けます など volume up and volume down buttons.

2.Once your phone’s logo will appear, let go of the power button but keep holding the Volume up and volume down buttons.

7.Once all the apps which you wanted to remove are uninstalled, again reboot your phone normally without entering into Safe mode.

And if you try to uninstall the Device Administrator apps you would a face warning message saying: “This app is a device administrator and must be deactivated before uninstallingに設立された地域オフィスに加えて、さらにローカルカスタマーサポートを提供できるようになります。」

So in order to uninstall such apps, you have to perform some additional steps before you can uninstall such apps. These steps are given below:

c.Under Security, tap on Device Administrators.

e.A pop-up message will come which will ask “このアプリをアンインストールしますか?" tap on OK to continue.

After completing the above steps, reboot your phone and the virus or malware should be gone. 

Method 2: Run an Antivirus Check

Antivirus is a software program which is used to prevent, detect, and remove malware & viruses from any device with an operating system installed. So, if you find out that your android phone or any other device is infected with virus or malware then you should run an Antivirus program to detect & remove the virus or malware from the device.

If you do not have any third-party installed apps or if you don’t install apps from outside of Google Play Store then you can live without an Antivirus software. But if you frequently install apps from third-party sources then you will need a good Antivirus software.

Antivirus is a third party software which you need to download and install on your device in order to protect your device from harmful viruses and malware. There are plenty of Antivirus apps available under Google Play Store but you should not install more than one Antivirus on your device at a time. Also, you should only trust reputed Antivirus such as Norton, Avast, Bitdefender, Avira, Kaspersky, etc. Some of the Antivirus apps on Play Store are complete garbage and some of them aren’t even Antivirus.

Many of them are Memory booster & Cache cleaners which will do more harm than good to your device. So you should only trust the Antivirus which we mentioned above and never install anything else.

To use any one of the above-mentioned Antivirus to remove virus from your device follow the below steps:

注： In this guide, we will use Norton Antivirus but you can use anyone from the above list, as the steps will be similar.

1.Open the Googleの遊び店舗 あなたの電話で。

2.検索 ノートンアンチウイルス using the search bar available under Play Store.

3.Tap on ノートンセキュリティとアンチウイルス from the top under search results.

4.Now tap on the インストールボタン。

5.Norton Antivirus app will start downloading.

6.Once the app is completely downloaded, it will install itself.

7.When the Norton Antivirus finish installing, below screen will appear:

8.チェックボックスをオンにします の隣に "I agree to Norton License Agreement and Terms of Use」と「I have read and acknowledged the Norton Global Privacy statement"

9.Tap on Continue and the below screen will appear.

10.Norton Antivirus will start scanning your device.

11.After the scanning is completed, the results will be displayed.

After completing the above steps, if the results are showing that there is any malware present on your device then the Antivirus software will automatically remove the said virus or malware and will clean your phone.

The above Antivirus apps are only recommended for temporary usage i.e. for checking and removing virus or malware that may be affecting your phone. This is because these antivirus apps take a lot of resources which affect your system performance and can make your device slow. So after removing the virus or malware from your device, uninstall the Antivirus app from your phone.

Method 3: Cleaning Up

Once you have uninstalled or removed the malicious apps, virus or malware-infected files from your phone you should run a thorough clean up of your Android device. You should clear device & apps cache, clear history & temporary files, any third-party apps which might affect system performance, etc. This will make sure that there is nothing left by malicious apps or viruses on your phone and you can continue to use your device without any issues.

You can clean your phone using any third-party app that is used for cleaning the phone, but in most cases, these apps are full of junk & ads themselves. So you need to be very careful before choosing any such app, if you ask me, do this manually instead of relying on some third-party app. But one app which is very trusted and can be used for the above purpose is CCleaner.

I myself have used this app many times and it doesn’t let you down. CCleaner is one of the good and reliable apps for removing unnecessary files, cache, history and other garbage from your phone. You can easily find CCleaner in the Google Play store.

It is recommended that once you have cleaned your phone that you should take a back up of your device which includes files, apps, etc. This is because it will be easier to recover your device from any future issues that may arise.
