We intend to answer all your questions in detail in this post. To start with, jucheck.exe is part of Java Update Mechanism. Java is a programming platform that numerous applications run on and is one of the most popular platforms for software development. This program is meant to check for updates and if it finds any, it notifies you to download the latest version.

Why is it necessary to keep Java updated?

It is necessary to keep your Java client updated at all times as Java is used to support many features on your browser and applications.

Furthermore, malware is known to find loopholes in this kind of scenario to infect your computer. It may be annoying to see the popup displaying on your screen again and again; but in reality, it is a good thing that you are being notified.

Here comes a twist. Should you press the Yes button to update Java when the popup comes? The answer is Yes and No. Chances are, it really is what it says it is but there are also chances that it is malware and is asking access to your computer or computer network.

How to check if the File is Legit?

Now let’s discuss how you can check whether the service is legit or just another malware which infected your computer. First of all, you should check if the application is digitally signed by a legitimate source. Digital signatures verify that an application is from a verified publisher/development and in most cases, doesn’t prove to be malware.

Here is an example of malware trying to access the hard drive on your computer. As you can see, the publisher of the software is unknown. Furthermore, it doesn’t have a valid program name. Most verified applications don’t provide the file name as the program name for which they are requesting access. Instead, the full program name is listed along with the publisher. Here is an example of the same process which is legit and doesn’t contain any malware.

How to Remove illegal Software from your Computer?

There are plenty of ways through which you can remove illegal software from your computer. There are tons of good antivirus software which do the job.

How to Stop the Automatic Updates?

  1. Open the Java control panel from the list of programs present on your start menu.
  2. Click the “Updatetab and uncheck the option “Check for Updates Automatically”.

If you have an older version, you can disable the process from launching at startup using msconfig directly as shown below.

  1. Restart your computer and check if the problem at hand got solved.
