Q: A window saying Need more hard disk space on this Mac is popping up when my browser is down

Back up your Mac if you have not done so already. To learn how to use Time Machine read Mac Basics: Time Machine backs up your Mac - Apple Support.

Remove the Symantec "anti-virus" product. As long as it remains installed it is unreasonable to expect your Mac to operate normally.

One or more of the following may be applicable:

Uninstall Norton Internet Security for Mac

Removing Symantec programs for Macintosh by using the RemoveSymantecMacFiles removal utility

RemoveSymantecMacFiles

You may have installed a fake "utility" called "Advanced Mac Cleaner." Like any software that purports to automatically "clean up" or "speed up" a Mac, it's a scam. To remove it, take the steps below. Some of the files listed may be absent. Back up all data before proceeding.

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/com.pcv.hlpramc.plist

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

          Services ▹ Reveal in Finder (or just Reveal)

from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. Log out or restart the computer.

*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

Move the following item to the Trash as in Step 1:

/Library/Application Support/amc

This time you may be prompted for your administrator login password. There's no need to log out after taking this step.

Step 3

Move this item to the Trash:

~/Library/AdvancedMacCleaner

Step 4

Open the Applications folder and move an item named "Advanced Mac Cleaner" (if it's present) to the Trash. Empty the Trash.

Hi. I've recently been having this problem. I'm running on 10.7.5. I did all of the steps and removed all of the files listed, but I'm still getting the pop-up message. Is there truly any end to this nonsense? T~T

This easy procedure will detect any kind of adware that I know of. Deactivating it is a separate, and even easier, procedure.

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. The malware will be disabled 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.

Great advice.

Try uninstalling ZipCloud.
