Q: How can I remove Megabackup from my Mac.

Apple most certainly didn't install Megabackup or other third party apps. To force quit apps like these check this topic for some pointers:

What is "MegaBackup"? How do I remove "MegaBackup" from a macbook air?

You may have installed ad-injection malware ("adware").

Don't use any kind of "anti-virus" or "anti-malware" product on a Mac. There is never a need for it, and relying on it for protection makes you more vulnerable to attack, not less.

Some of the most common types of adware can be removed by following Apple's instructions. If those instructions don't work for you, or if you have trouble following them, see below.

This easy procedure will detect any kind of adware that I know of. Deactivating it is a separate, and even easier, procedure that doesn't involve downloading anything.

Some legitimate software is ad-supported and may display ads in its own windows or in a web browser while it's running. That's not malware and it may not show up. Also, some websites carry intrusive popup ads that may be mistaken for adware.

If none of your web browsers is working well enough to carry out these instructions, restart the computer in safe mode. That will disable the malware temporarily.

Step 1

Please triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:

~/Library/LaunchAgents

In the Finder, select

          Go ▹ Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. Press return. Either a folder named "LaunchAgents" will open, or you'll get a notice that the folder can't be found. If the folder isn't found, go to the next step.

If the folder does open, press the key combination command-2 to select list view, if it's not already selected. Please don't skip this step.

There should be a column in the Finder window headed Date Modified. Click that heading twice to sort the contents by date with the newest at the top. If necessary, enlarge the window so that all of the contents are showing.

Follow the instructions in this support article under the heading "Take a screenshot of a window." An image file with a name beginning in "Screen Shot" should be saved to the Desktop. Open the screenshot and make sure it's readable. If not, capture a smaller part of the screen showing only what needs to be shown.

Start a reply to this message. Drag the image file into the editing window to upload it. You can also include text in the reply.

Leave the folder open for now.

Step 2

Do as in Step 1 with this line:

/Library/LaunchAgents

The folder that may open will have the same name, but is not the same, as the one in Step 1. As in that step, the folder may not exist.

Step 3

Repeat with this line:

/Library/LaunchDaemons

This time the folder will be named "LaunchDaemons."

Step 4

Open the Safari preferences window and select the Extensions tab. If any extensions are listed, post a screenshot. If there are no extensions, or if you can't launch Safari, skip this step.

Step 5

If you use the Firefox or Chrome browser, open its extension list and do as in Step 4.

Hi,

I had the same problem removing Mega Backup and Mac Cleaner.

Step 1:  Open Finder

Step 2:  Click on Applications (Left-Pane)

Step 3:  Scroll down on the Apps and locate Mega Backup.

Step 4:  Right Click App and delete (Send to Trash)

Step5:  Type in your password when prompted to Uninstall.

I am having the same problem as all of the posters who have not been able to remove the MegaBackup program.  Namely, the MegaBackupAgent process will not allow me to "Force Quit".  Once I was able to kill the process for MegaBackup, it allowed me to delete the application, but it still pops up notification windows and still seems to hijack my internet browser.  I have tried this multiple times over multiple days.  I went through the tutorials on reedcorner.net/arg to remove adware, and found Bundlore and another one and removed them manaully.  But things are still popping up that seem to be associated with MegaBackup.  Does anyone know how to remove it completely?

Also, I am not running a MacBook Air, but am running a late 2012 iMac with OSX 10.9.5.

Thank you in advance for any help!

The only way I could remove the "spamish" (or worse) Megabackup from my iMac was by using Finder, searching for Megabackup which revealed three related files, then by using  Move to Trash on each of them.

Yes.

Follow the instruction Linc posted above.

I was able to remove all the malware, thanks to phone support.

glad you got it all removed. care to share with the rest of the class what phone support had you do?

Tell me how to get rid of Mega Scan Backup since Apple put it in a third party apps in their EL Captain.

Actually, I was sent by Support that Apple put it in my Macbook Air. I would not lie to you, or how would I write it down to send it to you?

Well, thanks to the questions and posts and answers to them, I'm gonna call phone support when they open today and have them guide through the uninstallation process.
