Hello !
This is a feedback;
I was testing nod32 antivirus on my home linux (Manjaro with kde5). At one point the system froze to death a few seconds after I log into it via the graphic session.
Since Nod32 was in the last softs I installed, I took it to uninstall it. But I had to do it from a non graphic tty (Ctrl+alt+F12). So since the uninstaller isn't working under this condition I removed by hand
sudo rm -rf /opt/eset
After a reboot the session was stable enough so I could clean up eset from the system (service and ld preload).
sudo systemctl disable esets.service
sudo nano -w /etc/ld.so.preload
and delete the row libesetspac.so and save.
I did messed up my wifi adaptor with aircrack-ng and wireshark. It might come from me (I'm pretty sure of this) and linux is safe enough but it might be a serious bug.
