jucheck.exe” is part of the Java Runtime from Sun Corporation and not a trojan, IF it is located where it is supposed to be – usually something like “C:\Program Files\Java\jre1.5.0_10\bin\jucheck.exe

Viruses or Trojans are normally named identically together with other program files and operating system components to avoid detection. If the files are in a location where they don’t belong then YES there is a good chance that it is a malicious file.

Some malware camouflage themselves as jucheck.exe, particularly if they are located in c:\windows or c:\windows\system32 folder. Thus check the jucheck.exe process on your pc whether it is pest.

Just make sure to do some research before you do something, you could be deleting an important system file!
