I’ve just tried to install Avast on my Zenwalk (Slack distro) but I get an errors while unpacking tar.gz file:
tar: avast4workstation-1.3.0/lib/avast4workstation/lib/libavastengine-4.so.7: Not able to make link to `libavastengine-4.so.7.0.5’: operation not permitted
and for several other files in lib directory the same message.
