I don't think there is a virus problem with nsProcess.dll. This is a plug-in library which is commonly used in installer to stop processes for instance. On the net, other users had a similar problems with other anti-virus which detected this library as malicious, leading to a false positive.
If you run this library through http://www.virustotal.com, most of the major anti-virus don't consider it as a virus.
As you may see, Kaspersky doesn't consider it as a virus: "not-a-virus". This alert comes from the use of a library in the installer which allows to stop a process during installation. And some sensible anti-virus raise an alert considering it could be a problem... But you can install this version without problem.
