Raymond Lin created the software named Hash Utility to have a check against the malicious changes against the internet and other software. This tool is made to act as a security to the Internet, software and security applications. There can be a number of malicious changes that can affect the working in a wrong way of the Internet, or the software, or the security applications. The tool provides a security against these malicious changes.

Hash Utility works in two ways. First it verifies the source of the changes that is affecting the program. Then in the next step this software recovers the program from the affect. The tool works in two particular ways. Sometimes it is not able to stop the affect being done and works on the affect afterwards. In the second type, this tool checks for the list of the unprotected data value and validates the programs from being affected by these unprotected data.

The program is easily downloaded and installed by the user. It opens up with a single click on the icon. The tool is fast in its work also. This tool is compatible with Windows XP and also with Windows Vista. Hash Utility also works well with windows 7 and Windows 8 equally and better.
