How to get rid of MacPerformance

Hi Terri,

Thanks for getting back to me.

Looking at the two screenshots, your applications look fine.

You could remove the ClamXav one if you wish. Virus programs tend to slow your computer down sometimes.

There a few others with a circle and a line though it which means they are not compatible with MacOS Catalina as the new operating system drops support for 32 bit applications. You can download the 64 bit version from the developers website if you plan on using them. you can also download an application called Go64 which lists all your 32 bit applications and a way to get the 64 bit version.

Malwarebytes is a good application to have! Try running it and see if it find the adware/Malware such as MacPerformance.

If Malwarebytes doesn't find it, you can refer to the instructions from babowa on how to remove it.

I hope this helps.

PS: don't worry about AppCleaner since you can't find the application in question MacPerformance in your applications folder and run Malwarebytes instead.

Hi terririan,

First, I would download an application called AppCleaner.

Once downloaded, open AppCleaner and then go to your applications folder and drag the MacPerformance application to the window of AppCleaner to remove all traces of the application from your Mac.

Regarding other suspicious apps, could you take a screenshot of your applications folder and I can help you take a look and get rid of anything that shouldn't be there.

To take a screenshot of a window, Press Shift-Command-5 to see the onscreen capture controls.

1. Click Capture Selected Window . Your pointer changes to a camera .
2. Click a window, in this case your applications folder to capture that window.
3. A thumbnail of the screenshot will briefly appear in the corner of your screen. After a few moments, the screenshot will appear on your desktop.

Once it appears on your desktop, click the image insertion icon (it's the second from the last one) when you create a new post in Apple's Support Communities to insert the image to your post.

I hope this helps.

You may have inadvertently installed some malware onto your machine.

Try downloading an anti-malware program such as Malwarebytes https://www.malwarebytes.com - its free and I have it installed just as a precaution.

run a scan and it should detect it and remove it for you.

cheers.

Here is an article an removal instructions; it is adware/malware:

Malware tips is from the same developer as malwarebytes and he has been a long time contributor here.

Brallen01,

He already has a copy of Malwarebytes and has run it and it's still there. That's why I recommend that he try AppCleaner to help remove the application in question.
