Java is a very important software and plugin. It enables users to run a variety of new applications using various APIs and supports various types of digital signature devices. It also helps in playing various components of web pages and games. This file, JUCheck.exe, is an executable file responsible for Checking updates for Java.
Java Update Checker JUCheck.exe process
The legitimate file is stored in the following path inside the File Explorer-
C:\Program Files\Java\jre6\bin\jucheck.exe
If the file is located in any other location, it could be malware.
You might see this file being run inside of the Task Manager.
The Java Plug-in software is a component of the Java Runtime Environment (JRE). The JRE allows applets written in the Java programming language to run inside various browsers. The Java Plug-in software is not a standalone program and cannot be installed separately.
If you find the JUCheck.exe file working suspiciously, like using a large amount of RAM or CPU, you can try two major things.
First, you can manually download and upgrade to the latest version of Java from their official web page here.
The second thing that you can do is, type appwiz.cpl in the Start Search box and hit Enter to open the Uninstall a program Control Panel applet.
From the populated list in the new window, look for an entry called, Java. Right-click on it and click on Uninstall. Reboot your computer.
In case you do not find Java there, you need to open the Settings App and navigate to Apps > Apps and Features, and on the right-side panel, look for Java to uninstall it from there.
After rebooting your computer, you will have to delete all the residual files & folders left by this software.
As a matter of abundant precaution, you could run a malware scan using a free second-opinion, standalone, on-demand antivirus tool like Dr. Web Cureit.
I hope this clears up the air.
