Recently all of sudden I had started getting all sorts of internet connecitivity issues on my Office issued Mac book Pro. My internet would stop working all together on my Mac book Pro and the only way to get it working again was to reboot Mac Os.
After some closer inspection, I found that Kaspersky Endpoint Security pushed my company's IT was causing this issue. Since Kaspersky Endpoint Security does not contain graphical user interface to interact with, I had to come up with a way to unload it from system memory.
Below script unloads Kaspersky Endpoint Security Daemon. You need to run it after each reboot. You need to have super user permission.
sudo launchctl unload /Library/LaunchDaemons/com.kaspersky.kav.plist
WARNING: Above command stops Kaspersky Endpoint Security. Enter it only if you know what you're doing!
