Adware in Chrome, Edge and Firefox. AV can't find the problem

[Jumagoro]

Hello Guys,

first of all: Huge thanks for helping people in this forum. I'm from Germany so my english isn't the best and also the FRST-Reports are partly on german (i can translate if necessary).
To my Problem: A few days or weeks (I'm not quite sure) ago I noticed a huge amount of Ads in front of any google search within chrome, firefox and Edge. I already took following steps:
1. Reinstalled all browsers (nothing changed)
2. Searched for any malware/malicious extensions manually (nothing found)
3. Tried out different anti-virus programs (Avira, Kaspersky, Malwarebytes + Adwcleaner), but nothing was found. (I only ran / installed one at a time)
4. There is only one interesting thing: Malewarebyte's Adwcleaner can't find anything, but if I run the basic repairs afterwards, the ads are removed (until next reboot)

I also noticed the "Managed by your organization"-Label on top of the chrome settings and also can't explain why this is the case.
I hope you can help me with my case.

Best regards,
Gordian

Chrome sometimes says it's "Managed By Your Organization"---even if you don't have an organization! Here's what that means.

Thanks for the fast reply, unfortunately the ads are still there.

I ran the fixlist.txt you provided with FRST.
I turned off the chrome sync + deleted all stored sync-data.

Do you have any idea what adwcleaner does in the basic-repair steps (all additional configurations offline, as shown in the screenshot), since this fixes the problem until a reboot.

Hey Nasdaq,

thanks for your help.
I just reinstalled Windows to get a clean setup again. It seemed to me as the easiest and safest way.

Have a great day,
Gordian
