Freshly reinstalled XP, explorer always takes up 100 cpu????

Hit the Trojan again

The CPU usage is 100% due to the process

In the file, there is a "shell=filename" under [boot]. The correct file name should be "If not", but "shell= program name", then the program that follows is a "Trojan" program, which means that you have been selected for a "Trojan horse".

The situation in the registry is the most complicated, open the registry through the regedit command, click to: "hkey-local-machine software microsoft windows currentversion run" directory, check whether there is an unfamiliar auto-start file in the key value, the extension is exe, here remember: some "trojan" programs generate files that are very similar to the system itself, Want to get through the tricks by cloaking, such as "acid battery trojan", it will be registered in the registry under "hkey-local-machine\Microsoft\Windows\CurrentVersion\Run".

The explorer key is changed to explorer="c: Windows, and the only difference between the "Trojan" program and the real explorer is "i" and "l". Of course, there are many places in the registry where "Trojan" programs can be hidden, such as:

hkey-current-usersoftwaremicrosoft windows currentversion run", "hkey-users **software, microsoft windows currentversion run", the best way is to go to "hkey-local- machine software". Microsoft Windows CurrentVersion Run", and then search the entire registry for the filename of the Trojan program.

When did you get stuck, can you tell me about it?

1. The antivirus software is installed more, and all the monitoring is turned on, less monitoring is turned on or not monitored, and the virus is often checked and killed.

2. The software or driver is not compatible with the system, reinstall or upgrade the driver.

3. If there is a system problem or a Trojan, check and kill the Trojan to restore the system or reinstall it (**win cleanup assistant to check and kill the Trojan, do not replace it with other software, such as 360 Guard, etc.).

4. Memory, graphics card, and voltage instability can also cause crashes (if the memory is too small, add a memory module).

5. The temperature of common hardware such as CPU or graphics card is too high, which is most likely to cause card and crash.

6. If the hard disk has bad sectors, use software to repair the bad sectors of the hard disk, format the hard disk, repartition and reinstall the hard disk, and replace the hard disk.

7. Upgrading the hardware causes an incompatible crash.

8. Too many junk files, too many disk fragments, etc.

9. If it always doesn't work, it is recommended to overhaul it.

The computer should not operate at full capacity, that is, when playing games, watching **, watching web pages, and doing other operations with the macro is most likely to crash and blue screen, so don't operate other things when playing games, watching, looking at web pages, **.

If your memory is small, it is recommended to add a memory module to test whether the temperature of your CPU and other hardware is high. The other is whether there is a problem with the hard disk (this is just a general statement, if there is a problem, please ask me, I will answer the symptoms).

If there is a virus, it may be killed, so it's good to tease.

If you manually fork out some of the plug-ins flying around on the web finger page, you will find that the usage is low, and it also indicates that your CPU is too old.

Hehe! I had exactly the same problem as you the other two days! But I solved it!

I can guarantee that you must have video files and ** in your e-drive.

To solve this problem, you must first find out these damaged movies, slowly find them one by one, and after finding them, you just need to delete the damaged image files, of course, you don't need to delete them, you can move them to other places, but other places will be like this, it is recommended to delete them.

PS: If you open the E drive, the CPU will be 99%, which means that the corrupted file is there after double-clicking the E drive. If the CPU is 99% after opening a folder of the E drive, it means that the corrupted file is in a folder of the E drive.

If you suspect it, you put the corrupted file in the ** station,Then end the task from the task manager,Open it from the run,Then open the E disk to see if it still accounts for 99% of the CPU again,If so,It means that the files you deleted are no problem.,Look for it again.,Find it one by one, you will succeed。

According to my method, it will definitely be possible, and I will give points for so many portions. Hehe!

It should be a virus.,Kill or reinstall the system.。

The main reason for this phenomenon is that the CPU computing power is low and cannot meet the needs of the program, so it is recommended to upgrade the computer hardware.

1. Don't install too much software, and you need to clean up some software that is not commonly used.

3. There are many temporary files in the Internet and other systems, and they should be cleaned up.

4. The free space in the system area is too small, and the remaining space is expanded.

5. There are too many partition fragments in the system, and the partition fragments are sorted out regularly. Defragmenter software comes with the operating system.

Use Norton NOD32 or Kingsoft Antivirus to kill the virus.

You go to the task manager and take a look to see what program is occupied, and if it's a suspicious program, you can end it immediately.

You check and kill viruses and clean up junk The CPU is overloaded.

There is a virus stationed in this process, try to fix it with IE in 360.

Shut down the process and build a new one? TRY ...

Send the process up and take a look
