Malicious Software

A computer programmer that creates harmful computer viruses may use the names of common files that are associated with widely used programs to mask his malicious software. Scan your computer with anti-virus software regularly to check for files that may be harmful to your system. If you're suspicious of "jucheck.exe" and your anti-virus software doesn't determine it to be a threat, it doesn't necessarily mean that the file is safe.
Determination

If "jucheck.exe" is a threat to your computer, it's likely located in a different location, such as the Windows or Users folders. Right-clicking on the file and clicking "Properties" will provide you with its publisher. The legitimate "jucheck.exe" file is published by Sun Microsystems or Oracle, as Oracle acquired the former in 2010. Files associated with a different or unknown publisher are more likely to cause a threat to your computer. Attempt to delete the file by right-clicking on it and clicking "delete" or running additional malware detection software that may locate the problematic file.
