Is "boom 2" a virus? A popup appeared yesterday on my computer and will not go away?

Please post a screenshot that shows what you mean. Be careful not to include any private information.

You installed a fake "utility" called "Advanced Mac Cleaner" and/or "AdwareCleaner." Like any software that purports to automatically "clean up" or "speed up" a Mac, it's a scam.

To remove it, please take the steps below. Some of the files listed may be absent in your case. Back up all data before proceeding.

Malware is always changing to get around the defenses against it. This procedure works as of now, as far as I know. It may not work in the future. Anyone finding this comment a few days or more after it was posted should look for a more recent discussion, or start a new one.

If you paid for the software with a credit card, consider reporting the charge to the bank as fraudulent.

Step 1

Triple-click anywhere in the line below on this page to select it:

~/Library/LaunchAgents

Right-click or control-click the highlighted line and select

Services ▹ Open

from the contextual menu.* A folder named "LaunchAgents" may open. If it does, look inside it for files with a name that begins in either of these ways:

com.pcv.

com.adwarecleaner.

Move any such files to the Trash.

Log out or restart the computer and empty the Trash.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

Go ▹ Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.

Step 2

The malware is now permanently inactivated, as long as you don't reinstall it. This step is optional.

Delete the following items, if they exist, as in Step 1:

/Library/Application Support/amc

~/Library/AdvancedMacCleaner

There's no need to log out or restart after taking this step.

The problem may have started when you downloaded something, such as the application "FileZilla," from the "Sourceforge" website or some other Internet cesspit. Never visit that site again. All legitimate software should be downloaded directly from the developer's website or from the Mac App Store, if applicable.

"Advanced Mac Cleaner" may have been bundled with other malware that was installed at the same time. If you still have problems with web browsers after removing it, ask for instructions.

This is the Boom 2website. It is a program that purports to do more than change the treble and base of your iTunes music.

I have been getting this too and it has been freezing my mac. Wish I took a grab before telling it to go away.
