How to check a file, for example, which process uses the xjnzjp04 sys file

The solution is as follows:

1. Run "msconfig" and remove the hooks in front of the relevant items in the startup items!

2. Follow the prompts in the startup item, find the directory, and delete the file.

3. Clear the IE temporary cache and the system temporary cache.

4. Run "regedit" and find the following branch:

hkey_local_machine\software\microsoft\shared tools\msconfig\startupreg

Delete entries related to their names.

Restart your computer and if the problem is not resolved, run "regedit".

Find--Enter the name of the module with the error, and delete all the items you are looking for!

Upstairs methods may not work. Judging by the names of these two documents, they should be related. It is estimated that the sys file is in the system32 drivers folder, and the dll file is in the system32 folder.

None of these files can be deleted directly, even in safe mode. Because the sys file is loaded in the form of a driver when the system starts, you need to bypass the xp system if you want to get rid of it.

It can be easily deleted in a pure DOS environment, as long as these two files are deleted, it is estimated that there will be no error.

In addition, if you want to delete this file, you can also try this software xdelbox.

It is difficult to distinguish whether it is a virus file or not, but I can give you a way to determine whether it is a virus file First, restart the computer First, under the condition that no program is running, call out the task manager to see the number of processes, normal win xp system has 18-22 processes for the best, but if it is exceeded, it may be a virus Secondly, observe the CPU usage Normal should not be higher than 5% If it is too high, it means that a program is using a lot of CPU resources Third, you can observe whether there are redundant processes in the process, such as system processes However, if there are multiple processes at the same time, it may be a virus camouflage, and if there is a process with high usage in the redundant process, it is considered a virus parent file.

This is normal, the system will modify this file when it is running, this is virtual memory, sometimes large and sometimes small, don't worry. There is no virus.

This is occupied by the program, you look at what programs you have open, and you can delete the program when you close it.

This happens when you install the program in my documentation, and Iexlore is not the only one who is taking possession of it.

Folders will only be used by the explorer. The process is iexlore.

Unlocker can see if the file is occupied by that program and can force the deletion of the file.

The document shredder in the 360 security guard can also forcibly delete the documents of the filial piety, and the deletion force is greater.

There are some system files that you can't delete because the system has to run them to work properly. And some are some programs installed. When you want to delete it, if the prompt is occupied, go to the task manager to find the process corresponding to it and end it, and then delete the estimate.

There is also a possibility that some programs are being protected by the system, and you may not be able to delete them when you delete them, so you can get back on the machine or enter the safe mode of the system after the POST to delete them. It's almost time to get rid of the stuffiness! If it doesn't work, you can try a file shredder again and shred it directly for rent. Hope!

This is a page file, and its function is to save some infrequently used data in physical memory in this file when the physical memory is insufficient, so as to make space for other programs. When other programs are finished, they can read data from this file to continue running the program. The file has system and hidden attributes, and will generally be locked when the system is running, and cannot be deleted or modified.

If you want to resize the file, right-click on My Computer on the desktop, click Properties, the System Settings dialog box will pop up, select the Advanced tab, click on the Performance: Visuals, Processor Plan, Memory Usage, and Settings next to the virtual memory, the performance options will pop up, and click on the Advanced tab, where you can change the size in the bottom virtual memory. Under normal circumstances, for computers with less than 1G memory, it is recommended to set the page file to 2 times the physical memory, that is, 2048MB, if the computer memory is more than 2G, then the size of the page file can be appropriately reduced, and it is generally recommended to set it to 512MB to 1024MB.

In addition, if you delete the file, it may cause the system to malfunction properly, and the file will be automatically generated the next time the system is booted.

This is a virtual memory file, and when the physical memory is insufficient, the system will call a specific file on a part of the hard disk partition (that is, this is used as virtual memory, so as to meet the normal operation of each application. This file is automatically generated by the system, and the size will change frequently, you can delete it, but it will also be automatically generated after the system restarts, so you can ignore it. In addition, since it is an important file required by the system, the system has set it to be hidden.

Hehehe! This page is very protective! Except for hacker-level people! Otherwise, it would be impossible to open it!

The next little piece of software, unlock

Once installed, it's automatically integrated into the right mouse button, and you can directly right-click on the file you want to see, select unlock, and you can see which program is using the file.

Sometimes old files that can't be deleted or USB flash drive can't be deleted can be solved with unlock.

sys is the abbreviation of system, which means system, and sys is the system file of windows. Such as installation files, log files, driver files, backup files, operation files such as **, and some junk files and so on. are all sys suffixes of this kind.

If you are not at ease, you can use some software to back up the system, or optimize the software, system management software, these software can view unknown system processes and prohibit and remove them, clean up the system junk, protect the normal operation of the system, and prevent malware or programs from intrusion. If you find any unknown files or processes, you can delete and uninstall them in time.

I've found several files** and you don't have this, so I don't know what to do.

You can try using the process manager in 360 to see how it is introduced.
