many problems

Please run Etrecheck and post its full report here.

Use the “additional text” button and paste the report into the text box.

As P. Phillips said, it is your choice, but you are the one who came asking for help.

It is like going to the doctor with an ache and refusing to answer his questions.

Etrecheck does not modify your mac in any way, and does not reveal any personal information.

It was created expressly to help users here help others by providing information about the mac hardware and software of the affected user.

It is used here dozens of times every day for this exact purpose. Your call.

You have remnants of "hola", which appears dubious.

There are also other stuff in the "clean up" section - this is stuff that was probably uninstalled but some pieces of it were left behind. These bits and pieces are not doing anything now, but by cleaning them we can have a clearer report.

One other thing of concern: using vpn, except to connect to workplace or school network according to the requirements and instructions, does NOT increase your security; in fact, quite the reverse:

Public VPN are anything but private

There is this thing "hola" - of which some part seems to have been uninstalled, but not all of it. This is suspicious. Its purpose seems to make it seem that you are somewhere else - presumably to access resources that would be geofenced. This can open the door to security issues (in fact it is just another sort of public vpn).

Very much agree with @Luis S evaluation and to add

1 - Applications/NordVPN.app also a VPN though better that most others but is still what it is - VPN.

2 -  Google Chrome 44.10 % (Google LLC) from the Top Processes Snapshot by CPU:. That application though popular is all well known to a CPU / Memory Hog and harvests your Data for Resale to the Highest Bidders

The are Alternatives without the Over-Head of Google --- > www.brave.com come to mind.

I have been remiss 😔 on thanking you 🇨🇦 for the Solved Designation earlier in this question

Ok that is a user choice.

But, it is interesting some ( not All ) are willing to download and install --->>>

Any Third Party Applications that will interfere with the normal operation of the OS,  is an invitation for disaster and comprising the Operating System

Certain Applications maybe available on the Apple Apps Store - this only means the Developer is prepared to pay Apple a portion on each sale. What the Application may do to the computer is up to the User to check this out before purchase

Any of the below should be removed as per Developers Instructions

>>>> Below is only a Partial List <<<

This will include CleanMyMac , This will include BitDefender , 

This will included Norton Antivirus , Sophos Av Software

Intego AntiVirus, McAfee, MacKeeper, Avast AntiVirus

Ad Guard, Webroot , ESET , Kaspersky Antivirus. Anti virus

AVG AntiVirus  

Trustee 

The The Built in Security  is all that is required.

Therefore arrive at your own conclusion

Very much agree with @ Luis Sequeira1 and post back the Full Report

Post back the Full Report - copy and paste - using the Additional Text Icon ( 3rd Icon to last )

Should the User ( you ) decide at a later time to download, install and post the Report - We will be happy and willing to assist in dissecting the Report and Report the findings.

I fell it is important to say ( If I may @ Luis S ) that this We is either or both of us.

The whole report.

It is too long to post directly in the message;

click the "additional text" button:

and paste it into the text box.

To add to above from @ Luis S - it has been reported by very reliable sources that even Apple Support ( the really Support from Apple ) has been reported to use this very same Application to Diagnose Computer Problems.

Again - your choice

There has been sufficient advise offered, by more than one Contributor, for the User to make an informed and educated choice what the next course of action is required for this computer.

The suggestions have been put forth on a volunteer basis, in good faith and in the best interests of the computer.
