PC Pitstop Analysis

nnrun.exe - According to CA this software is related with the categories below:

Adware: Software that displays pop-up/pop-under advertisements when the primary user interface is not visible, or which do not appear to be associated with the product.

Hijacker: Any software that resets your browser's settings to point to other sites. Hijacks may reroute your info and address requests through an unseen site, capturing that info. In such hijacks, your browser may behave normally, but be slower.

Spyware: Any product that employs a user's Internet connection in the background without their knowledge, and gathers/transmits info on the user or their behavior. Many spyware products will collect referrer info (information from your web browser which reveals what URL you linked from), your IP address (a number that is used by computers on the network to identify your computer), system information (such as time of visit, type of browser used, the operating system and platform, and CPU speed.) Spyware products sometimes wrap other commercial products, and are introduced to machines when those commercial products are installed. See also Adware.

nnrun.exe is spyware/adware. PC Pitstop recommends strongly that all adware and spyware be immediately removed. This application category consumes considerable system resources and the performance gain is quite noticeable. Furthermore, adware/spyware pose a security risk to your computer as it sends your personal information back to the mothership.
