What is jucheck.exe?
Many Java users, and possibly yourself, are confused about an executable file called jucheck. So exactly what is jucheck, and why is it an essential file?
In essence, the jucheck file stands for Java Update Scheduler. Sun Microsystems developed this file to tell you when one or more Java files are out of date and that there is an update available to better use programs that run on Java.
Is jucheck.exe a virus or malware?
So why do computer users suspect the jucheck file is either a virus or malware?
While it is very important to keep your Java files updated, otherwise your system is less secure, and without the latest patch updates, to keep your computer safe, there is a catch.
You see the jucheck file only notifies you when there are Java files to be updated, but it does not automatically update the file for you. You do have the option not to update your Java files.
However, while you have the option to decline, the jucheck file is rather tireless in its notification process. Until you do update your file, Sun Microsystems designed it to be rather pesky. Expect that every time you restart your computer that Windows will check the jucheck file.
But while the jucheck file is a good thing, and helps to keep your system updated, unfortunately, many viruses and malware are buried in Java files that are not legitimate but may contain malware.
So while the jucheck pop-up that shows up, again and again, might be annoying, the alternative is to update your Java whenever it shows up.
However, there is one big caveat. Don’t just click yes for the update button when jucheck notified you that it’s time to update your Java file. While the chances are great that it is an approved Java file, at the same time it could be a file installing destructive malware on your computer.
You can in part check the file by looking at its digital signature to see if it’s a file created by a verified publisher/developer, by checking the publisher’s name and the file name. A legitimate program name, such as Java Auto Updater, and a publisher’s name such as Oracle America Inc are signs that it is a genuine file.
But why play a guessing game? Instead of clicking that update button, instead, go to the official Java website and update your Java manually. That way you guarantee you get the real deal.
Where is the jucheck.exe file located on your computer?
In the vast majority of cases the jucheck.exe file, also called the Java Update Checker, is located in the C:\Program files\java\javeupdate\jucheck.exe file.
The file can also show up in other locations on your computer but that is pretty much a sign that your computer is infected with an illegitimate file.
How to remove & uninstall jucheck.exe
Should you remove and uninstall the jucheck.exe program?
While you can uninstall it, a better solution is simply to disable it.
There is no reason to legitimately uninstall the program because it serves a legitimate purpose.
How do you stop jucheck.exe processes?
However, if you go to the official Java Website once a month and update your Java manually, you can disable your jucheck.exe file so that it stops giving your pesky
signals to update.
To stop the jucheck.exe process do the following steps:
- Click on Start and go to the Control Panel.
- Once you are in the Control Panel, double-click on the Java icon
- In the new window, go to the Update tab.
Then Uncheck the option to Check for Updates Automatically checkbox
A warning that you should leave automatic updates enabled will pop up.
Ignore the warning and Click on Never Check. That’s it. Should you change your mind, it’s a lot simpler to reverse the procedure and start the jucheck.exe procedure as normal rather than having to completely install the entire file.
Is jucheck.exe causing High CPU Usage?
This is quite normal and you can tell by going to your computer’s task manager, finding your jucheck.exe and checking the CPU usage.
However, before you go to radical steps such as removing the program entirely, consider restarting the program, restarting the windows, and also turning off any extra features in the program.
Also, run a scan to see if you have any malware programs masquerading as a legitimate jucheck file.
How to check if jucheck.exe is causing high disk usage
How to check if jucheck.exe is causing high disk usage? Use the same process as before with the task manager. And quite naturally, you would use the task manager to check the GPU use.
There are plenty of solutions for these programs including adding extra ram, eliminating other programs, or updating your Windows scheme. However, the number one solution for all these problems is to eliminate trojan programs that are causing your computer to operate abnormally.
Scan your computer for malware, run a Windows repair utility and do not forget to run checkdisk. If you find a suspicious program, use either a specialized program to remove it or, use system restore point to revert your computer to safer settings.
Your jucheck.exe file is not anything to be worried about as long as you understand its value and your options to disable it should you want to just manually update your Java files periodically.
