Jucheck.exe is java's update checker. Why someone flagged it as dangerous is beyond me.
BM

Jucheck.exe will check on the internet for available updates for the Java Virtual machine installed on your computer. If updates are available it will notify you and/or manage the download and install of the updates.

Java wants to update
Chris

There is a version residing at "C:\Program Files\Java\jre6\bin\jucheck.exe" -- size 422K (Windows 7) published by Sun Microsystems that is a legitimate checker to see if you have the latest Java version. If you do not need Java, you can uninstall it or also you can disable the automatice update feature in the settings. Java is not critical to Windows but may be required by some applications.
Terry

still do not know if it is safe or I need it to run properly

Only need one of these files so delete any that have notbeen accessed in a while. Or check for updates manually and remove this exe file.

It's Java Update. Nothing wrong with it!
Rhys

it is simply used as a Java Updater, assumung that the program really is as it says.

I believe it's some kind of Nazi software used in WW2
SS

It comes with a brand new machine, installed at C:\Windows\System32, so it is hardly true that 94% of the ocurrences in this folder are dangerous.
Carlos

We have received a brand new laptop from Dell with Windows 7 Home Premium on it. UAC reports jucheck.exe running from "C:\Windows\System32\jucheck.exe". This seems contrary to the information available here.
Sean

It's the Java runtime updater If you use a program written in Java, then you'll need this to run.
Firefly

Found four on my computer, three in the right places and one in win32 (the one that keeps prompting the security check). Think I'll delete that one as I don't trust it based on other information from around the internet.

Java updater - Windows Vista / 7 complain when it tries to check unless you accept it.
Joe

jucheck.exe dosen't show up on file searches, so it hides it's location, therfore, it's OBVIOUSLY spyware or some other malicious program.
Superdog

If you look there is a java scheduler called jusched.exe not jucheck.exe, the jusched is registerd as sun micro and is in C:\Program Files\Common Files\Java\Java Update\jusched.exe

Its coming up crashed Sims 3 a couple of times. I set it to not notify about 5 times. I finally gave up and just uninstalled Java from my system.
scm

It was in my C:\Program Files\Java\jre6\bin\jucheck.exe. My norton program said it could be trusted, so I took the chance. It just updated my java.
Leo

This is a safe file used for Java Updating
Kevin (further information)

To make sure, I updated Java to the latest version directly from Java.com. Why can't but jucheck.exe keep saying I should install the latest version of java, that bothers me; why can't it detect the newest version I installed? It looks suspicious to me
Ios

You can delete it if you like, though you'll have to update your Java manually if you do.

It seems like jusched.exe is the java updater. Why would jucheck.exe with such an obvious similarity appear?
Ted

java update check - completley harmless :)
Zahra

it is a java updater, IF its where its supposed to be, otherwise its a trojan. It ruined my computer once so watch out

A Trojan horse if runs from C:\Users\AppData\Local\Temp\jucheck.exe

No this is NOT a java updater.Anything with the name juchuck.exe and jucheck.exe is a virus pretending to be a java updater. I just recently had to deal with removing this nightmare!If you dont believe me first notice how the user of it is UNKNOWN.Red flag right there.Secondly java does NOT need your permission to check for updates unless you change the setting manually.So this should also send up a red flag.The proper java update device is..um i forgot but if you press ctrl shift esc you can see it in the running programs section.My point is that its a virus that is hard to detect.

Unless the publisher is Java, then it's a virus. People are so quick to think people are dumb and not know what jucheck.exe is, but it is actually a virus that uses the same name. Click more details on the popup and see where the file is. If it's not in a Java folder, then it's a virus.

it turned out to be a trojan virus
Michael R

It's a virus, my AVG said it was a threat/
Melissa

Found it in C:/Windows/Prefetch. Since it's not hiding itself, and is visible, and it won't let you not download it, then it is most likey needed in order to have Java. Scanned it just now. It isn't hidden, no suspicion, nor detection. Seems fine.
Brooke

Avira AntiVir told me it was a trojan virus. It quarantined it and everything.

Java has a big hole, used by outsiders to control your computer. The type of infiltration is Trojan. The Trojan contains a backdoor. It can be controlled remotely. The trojan creates the following files:
Glaukus (further information)

When you uncheck the automatic updates in Java's properties, the checkbox becomes checked when you start your system up. Therefore it is a form malware. Do not trust it.

After update did block partialy few of my programs. I did uninstaled and restore the system with few days before updating
