What is zlib.dll?

zlib is a common software library used for data compression. zlib compressed data is typically written with a gzip or a zlib wrapper. zlib is something of a de facto standard, to the point that zlib and DEFLATE are often used interchangeably in standards documents, with thousands of applications relying on it for compression, either directly or indirectly.

Overview

zlib.dll is loaded as dynamic link library that runs in the context of a process. It is installed with a couple of know programs including Mah Jong Quest from Compaq (remove only) published by WildTangent, Family Feud [PopCap] from PopCap Games and Family Feud [PopCap] by PopCap Games. The file is digitally signed by Trend Media Corporation Limited which was issued by the VeriSign certificate authority (CA).
