But I have installed it! I've extracted the tar to my /root/ directory, then ran:
# bash /libavastengine-4.1.10/install_so.sh
accepted the default settings, then
# bash install.sh
which gives me this error:
avast!4 engine library 'libavastengine.so.4.1.10' is not installed!
Run './libavastengine-4.1.10/install_so.sh' script to install it!
