Q: Yahoo website is causing MBP to crash

I have a mid 2012 13-inch MacBook Pro currently running OS X El Capitan 10.11.1. Regardless of which browser I'm am using (Safari, Chrome, Firefox), the Yahoo website causes my MBP to heat up quickly and the fan will start to spin endlessly. If I catch it early enough I can close out of the website and the other apps still function but the laptop remains hot and the fan continues to run. If I try to shut the MBP down normally, the laptop will not do it and will look like this: images.jpg

I have let the laptop sit like that for 3 hours before just to see if it could correct itself but it didn't. In the end I have to force-shutdown by holding down the power button. For some reason it is only Yahoo's website that does this. My friends who also have MBP's do not encounter this problem. I've run malware and virus checks and come up empty every time. I have done disk repair and it says the disk is okay. I cannot find any solution to this problem other than avoid visiting Yahoo. 

Note: I have I have had this problem since upgrading from Yosemite to El Capitan.

If anyone has a clue what is going on please let me know.

MacBook Pro (13-inch Mid 2012), OS X El Capitan (10.11.1)

A:

It appears something called K9 Web Protection is installed, or was installed at one time:

 

http://www1.k9webprotection.com/

 

Same goes for "CleanMyMac". Any system that has been affected by it will not work properly.

 

Try uninstalling "K9 Web Protection" first, but if that is not successful the only certain remedy for CleanMyMac's effects on a Mac is a complete system erase and reinstall.

    Okay we have some results! After deleting K9 web protection browser I am not having any issues navigating the internet and the Yahoo website is not causing Safari to freeze or the computer to restart.

    I have a couple of questions for you.

    1. I deleted CleanMyMac a long time ago. Can I delete that MacPaw file found in LaunchAgents? Can the AdobeARM file be deleted as well? I also deleted Malwarebytes too. Can that file be deleted in LaunchDaemons?

    2. Is there any web protection browser you know of that won't cause this issue? I had a roommate who used my laptop to research questionable things on the internet which is why I added the browser and I liked that it blocked questionable websites.


    I appreciate your time and dedication to this problem. You've been a great help

    Can I delete that MacPaw file found in LaunchAgents?

     

    Yes, but just be aware that CleanMyMac2 littered a Mac with all sorts of components that its uninstallation instructions published at the time did not remove, despite their claims to the contrary. I can only rely upon the notes that I took at that time, but the one User Launch Agent com.macpaw.CleanMyMac2Helper.diskSpaceWatcher.plist can be safely removed.

     

    You may or may not find these other files:

     

    /private/var/run/com.macpaw.CleanMyMac2.Agent.socket

    ~/Library/Application Support/CleanMyMac 2/CleanMyMac 2 Helper

     

    If you do, I would delete them as well.

     

    The effects of having used such "cleaning" apps is a different subject than merely removing all their components, rendering them incapable of inflicting additional damage.

     

    Can the AdobeARM file be deleted as well? I also deleted Malwarebytes too. Can that file be deleted in LaunchDaemons?


    AdobeARM is Adobe's automatic updating service for Adobe's Reader app. As I wrote earlier I can think of no need for it, since OS X already includes everything it needs to render and manipulate PDFs. I would delete "Malwarebytes" also, for the same reasons I expressed earlier about using Google's products. There is no way I would ever want anything like that on my systems, because I have no way of determining the information they are collecting, where it goes, how it's used, or what they are doing to my Macs.

     

    If you want to share your Mac that's OK, but the only protection I recommend is to create a separate User account for your roommate – without Admin privileges. That way, any damage that can be inflicted will be limited to that account. Don't give out your login credentials, Apple ID or password to anyone. "Managed" accounts can be limited even further, limiting their Web searches to those you specify, or preventing access to certain websites, or leaving a general choice to Apple's defaults. Those features can be found in System Preferences > Parental Controls. Despite the name it's not just for parents. It's very robust and customizable, and unlike third-party "net nanny" products, it won't crash your Mac.
