Help! Regular kernel panics on MPB '10 running El Capitan

Hi guys,

I've had regular kernel panics for the last 4 months or so.
About a month ago this (probably) resulted in a HDD issue where I couldn't boot anymore or repair the disk in Recovery. It was fixed in a repair shop, shortly after the problem returned, and in the shop they made a clean install where they removed all app data and reconstructed my fusion drive, only transferring user data and the Apple Mail app.
It seemed to fix the problem, yet the kernel panics have returned and today I had to rebuild the drive again with Disk Warrior since the boot issues returned. It might be related to something graphic or related to RAM, since it crashed after running several Facebook tabs in Safari. Honestly I don't know.

After a dialogue with the Mac shop I got the feedback that the could possibly be caused by:
- The 16 GB of ram I upgraded myself about a year ago might be faulty
- It might be related to the fusion drive and I could try to split the two drives
- It might be something in El Capitan that's incompatible with my computer/software
- It might be the cable from the original internal HDD to the logic board that's faulty (least probable, all hardware tests are positive).

Two recent kernel panics as well as my system specs are posted on the link below, please help me locate the cause of this issue!
Thank you SO much in advance.

Hello and welcome.

Yes, it could be related to the RAM, a software issue, or a cable. The first thing that sticks out to me in your kernel panic log, is that you have Avast Antivirus installed:

com.avast.AvastFileShield 3.0.0
com.avast.PacketForwarder 2.1

Antivirus apps are notorious for causing system instability and slowness, especially if they have a "live" mode where they scan every single file that you open, access, or execute. I would try uninstalling Avast and see if the kernel panics stop.

Also, is the Kingston 120 GB drive an external, or did you replace the optical drive with a hard drive adapter?
