It looks like there is a virus in the Nokia 5230 mobile phone, what should I do?

I've been playing with my phone for many years, and I hope it helps.

If you have a certificate, you can open the settings of program management, select "all" for software installation, select "off" for certificate detection, and the phone will automatically ignore the time problem when the software is installed after setting (of course, cracking the phone is the most straightforward).

The icon should be in the "My Assistant" or "Treasure Chest".

360 from the official website does not need to sign, but there will be some problems if you sign. Security Manager and 360 will conflict, and I personally recommend choosing 360. You can try the following method:

If it really doesn't work, there is only a grid machine...

Soft grid machine! Enter * in standby mode

If the password has not been changed, then enter the security password 12345 and it is OK! Just wait for the auto-restart! It is recommended to back up your phone's address book, text messages, or whatever!

After the soft grid, all user data will be erased and restored to the factory state! And it's best to copy the data from the memory card as well! Let's format the memory card as well! Hope!

This is not poisoning, 360 and security stewards will conflict, and I personally recommend that one of the two is enough.

Now you can turn off or uninstall Security Manager, then reinstall 360 and the icon will appear.

Grid machine, grid card! There are a few points to pay attention to in the mobile phone grid machine: keep the power absolutely sufficient, do not try to shut down the grid on the way, do not plug in the charger, etc., if it is violated, it may cause serious consequences such as burning.

There is also a hard grid may be a little damage to the hardware of the machine, not to be foolish, do not use the hard grid when the machine can not be turned on, and one thing to note is that the line 2 will disappear after the grid, and it must be restored to the kf flash.

If there is a problem with the mobile phone, you can use the phone!

Hello, try hard grid, hard grid machine This method is generally used when the system is chaotic and can't be turned on:

After powering off, press and hold the call button, the number 3 button, and the * button at the same time, and then press power on. Don't let go, at this point the phone has already started to format (some older models will have an English waiting note when the grid is displayed). Press one piece, don't let go of one, and wait for the phone to automatically turn on and ask for the input time to complete the grid.

This formatting is more thorough and does not cause invalid formatting.

Other: Turn off and press the * + power on button, and start the grid without any prompt.

Precautions: Sufficient power must be guaranteed when formatting, and generally it should be operated under full power. It's a good idea to uninstall all the software and see if you get any similar "system errors".

If there are no similar "system errors", then proceed to the grid. Do not attempt to shut down the machine during the grid, do not plug in the charger, etc. Also, try to give priority to the soft grid.

The software part that was originally installed on the expansion card will be affected, so under normal circumstances, the important data of the expansion card will be backed up and then formatted, and all the programs saved in the E disk will be reinstalled after the format of the mobile phone is completed.

In short, the most thorough formatting steps are: uninstall all the programs that can be uninstalled in the program management Remove the extension card Check if there is a system error Format the phone Install the expansion card Format the expansion card (the phone at this time is the purest basic system) Install the programs that need to be installed Restore contacts Complete.

c. Preparation before the grid machine and resume work after passing the machine.

1. Back up your contacts Open the Business Card Holder option Mark All and Copy to the memory card.

2. Format the mobile phone See a and b above for the operation method.

3. Restore Contacts Open the Business Card Holder option Copy from the memory card.

4. Use a card reader to back up the files that need to be backed up in the extension on your computer.

5. Format the expansion card with your phone.

6. Restore the English-Chinese dictionary thesaurus.

9. Adjust your phone settings.

10. Set the Data Management --- Memory Card option to back up phone storage, and keep a relatively clean backup of phone settings on the expansion card.

11. Install the required software.

There are many reasons, and it's hard to say which one is specific, so let's choose the important one:

1.Crashes are inevitable. A smartphone is a simplified computer, with a CPU, memory, and it is normal for it to freeze when it runs wrong. The computer still freezes.

2.There is not enough memory. Multiple processes are opened at the same time, the memory is not enough, and the system crashes. If so, it's okay to shut down unnecessary processes.

3.Software Conflicts. Some software is conflicting with each other, which will cause running errors, and the phone is not like a computer, so it freezes. Uninstall some of the software and try it to see if it will get better.

4.Hardware issues. It's that there is a problem with the CPU of the machine itself, etc., and this is after-sales.

Generally speaking, your machine is licensed under warranty, and when it crashes, it will be directly taken to the after-sales service and let them solve it. Many times you have asked them to change the motherboard for you

Happy playing!

Please try the soft grid.

Enter * after powering on* The passcode is 12345

Please save the ** book before the soft grid.
