~de1a55.tmp is a temporary file. It resides in the temporary folder on Windows systems but also runs through the Windows registry. Our software engineers do not currently know if it is safe or malicious–they are getting to it.
The Windows registry is a database that collects all the process files in one location. Because of this, Windows computers can run at their regular speeds. Without the registry, process files would have to search through the whole system every time they activated in order to connect with the proper programs and hardware.
The Windows registry remembers where these programs connect and assigns that value to them every time; this is how it helps a computer run quickly. But sometimes, through no fault of the user’s own, this registry can become cluttered or damaged.
Also, process files may not update correctly or uninstall the way they should. This is why it is good to regularly scan and clean a computer’s registry. You can obtain a free scan for your registry at www.ZookaWare PC Cleaner.com.
