First, I suggest you update the virus database and carry out virus killing again:

1, HarmonyOS system: mobile phone housekeeper >; "gear icon" > antivirus software update and network killing, when only WLAN is connected or all networks are selected.

2.EMUI8。 X and below: Click on Mobile Manager >; Virus detection > "gear icon" > manually update the virus database. It is suggested that you turn on the switch of automatically updating the virus database and updating the virus database only under WLAN, so as to update the virus detection database in time and improve the system security.

3、EMUI 9。 X & Magic UI 2. X and above: mobile phone housekeeper > "gear icon" > network virus killing, only when WLAN or all networks are connected.

Second, if the problem is not solved, I suggest that you restore your mobile phone to the factory settings:

Restoring the factory settings will delete the data in the device, including your account, system settings and data, installed applications and their data. In order to avoid the loss of important data, please back up your own data in advance (QQ and WeChat need to be backed up separately), and be careful not to back up suspicious applications to avoid being poisoned again when recovering.

Enter Settings, search and click Restore Factory Settings, and complete the operation of restoring factory settings according to the screen prompts.

3. If the problem cannot be solved after the factory settings are restored, the virus may have tampered with the system files. Please back up important data in advance, and bring the purchase voucher to Huawei Customer Service Center for testing and processing.

Tips:

It is recommended that you use the application market to download and install applications to ensure the security of the system. In daily use, it is not easy to click on unknown links.

Please feed back the link of the poisoned website to Huawei's after-sales service hotline, and the mobile phone housekeeper will add the website to the background monitoring. The next time you visit or other users visit this kind of website, the browser will send out a reminder to avoid accidental clicking and poisoning the mobile phone.
