What To Do
The libz compression library must be available in order to install Sophos Anti-Virus. If the 'zlib' package has been removed, please install 'zlib' in order to run Sophos Anti-Virus.
On 64-bit operating systems the 32 bit 'zlib' package must be installed.
NOTE: Some 64-bit operating systems provide a package of 32-bit libraries for compatibility with 32-bit applications. For example, on Ubuntu we recommend to install the 'ia32-libs' package, and it's dependencies.
