Your computer restarted because of a problem-Catalina update

Hi there, I am having a couple of problems, I think after I have updated my macOS to Catalina. I also have a problem with my search engine, it keeps redirecting me to yahoo search. I have done all the steps recommended in that case but still yahoo search is on. Below, I post the message displaying in my mac in every restart. Any suggestion will be very helpful. Thanks in advance.

If your Mac restarted because of a problem - Apple Support

If you suspect you have installed adware/malware:

>System Preferences>Profiles. found next to Accessibility (click into it and then remove all the suspicious things from the list.) May or may not be present if no profiles found.

Adware Removal Guide—Manual removal of : http://www.thesafemac.com/arg-identification/

Try running this trusted utility https://www.malwarebytes.com/mac/

also Verify you are not using SOCKS proxy:

>System Preferences>Networks>Advanced>Proxy uncheck the box

Adware/malware launch daemons can set SOCKS proxies without user participation.

(SOCKS is an Internet protocol that exchanges network packets between a client and server through a proxy server.)
