Frequent kernel panics

My iMac 2017 has a kernel panic 2 or 3 times daily. Ive copied and pasted the latest Etre out5put below. Any insight and how to resolve the issue would be greatly appreciated.

Uninstall Bitdefender and any other anti-virus apps, cleaning apps, and third party security software by following the developer's instructions. These types of apps are not needed on a Mac and usually cause more problems than they solve plus they impact system performance.


One of the Kernel Panics also has "net.sf.tuntaposx.tap" & "net.sf.tuntaposx.tun". I'm not sure what app these are for, but you may want to consider uninstalling the app they are associated with if uninstalling BitDefender does not solve all your problems.


If you still have problems after uninstalling these items, then run EtreCheck again and post the new report here.


You may also want to run the Apple Diagnostics to see if any hardware issues are detected.


Disconnect all external devices in case one of them is causing a problem.

+1 In addition, after BitDefender has been uninstalled. Please run a fresh EtreCheck report and look for any parts of it left over. If there are any please use FindAnyFile (the free version is fine) to locate them and Trash them and empty the Trash. Then boot into the Recovery Partition and install Mac OS, something has damaged it (probably BitDefender) and has disabled Mac OS's own security. This needs to be fixed ASAP! The type of install for Mac OS I am suggesting only fills in missing or damaged pieces of Mac OS. It does not affect your data. That being said though please ensure you have an to date backup (Time Machine or a bootable clone) to safeguard your data!
