Edit this file with your favorite text editor as root:
/etc/ld.so.preload
Safe example, through `sudoedit`:
sudoedit /etc/ld.so.preload
If it contains:
libesets_pac.so
Change the content to:
/opt/eset/esets/lib/libesets_pac.so
Save the file and the library will be preloaded for new processes.
You should restart the system to make it active for all processes.
