What is jucheck.exe doing on my computer?
“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 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 and if this is the case then deleting it is recommended.
Non-system processes like jucheck.exe originate from software you installed on your system. Since most applications store data in your system's registry, it is likely that over time your registry suffers fragmentation and accumulates invalid entries which can affect your PC's performance. It is recommended that you check your registry to identify slowdown issues.
