I have a malware on my mac, how do i get rid of it?

My macbook has been experiencing many popups, it is infected and I need to get rid of it.

Click here and follow the instructions, or if there’s a type of adware not covered by them on the computer, these ones. If you're willing to use a tool to remove it(you don't need to, but may find it easier), you can instead run Adware Medic; this link is a direct download.

I think I have a virus on my mac, how do I get rid of it?

For the last few weeks, my mac has been working very slowly. I heard it might have a virus. Does anyone know how to find out if you do have a virus and how to get rid of one on a mac?

There are no OS X viruses. If your computer is running slow it's not because of a virus. You might see the following:
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior. Versions 1.5.1 and later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.

In Plugins I have two versions of Adobe Acrobat - how do I get rid of the old one?

In Plugins (and Applications) it shows two version of Adobe Acrobat: 10.1.13.16 and 11.0.10.32 How do I get rid of the old one?

Thanks! Especially for the last sentence :). Now that I found the path, I see the Adobe Acrobat 10.1.13.16 is the full version and Adobe Acrobat 11.0.10.32 is the reader. Should I delete the Reader?

Why does my MacBook Pro screen have white marks on it and how do I get rid of it?

My MacBook Pro started having these white marks right in the middle of the screen and I don't know how to get rid of it. I brought this MacBook online so I only have the invoice from seller. Is this sufficient evidence to show apple to replace under warranty?

you will have to bring it to apple so that they can determine that.

Why do I have a canadian IP address, and how do I get rid of it

I have Fios service, and for some reason I now have an IP address that appears to be Candian. It starts with 74. and www.whatismyip.com says it is out of Toronto, Canada.
I am now having problems accessing websites such as cbs.com, hulu, and Rhapsody (which I pay for, through Verizon Wireless). How can I get my IP address changed/renewed to an US one? I tried rebooting my router, but that was no help.
Daniel

You can always call Verizon Tech Support and tell them you need a new IP address. They can release the address so it forces a new IP address. 888-553-1555

I am using Firefox 4.01 on a Mac, I have entered usernames while logging into Yahoo and sometimes, because networks are slow, I have put the password in too - How can I get rid of usernames offered at the login stage?

When I go to log into Yahoo now it offers me a list of possible log on ids. Because of mistakes in typing some of them have the passwords on them too. How can I remove this list?

That worked and was really convenient - and I wouldn't have guessed it in a year. (Well I didn't guess it all last year anyway!)
Thanks

I seem to have two apple id's. How do I get rid of one?

I am trying to access the Cloud to find a lost document, but I seem to have two apple id's, one is verified. I can't access cloud. How can I do that? Is there any other way to find my document? It means another week of work if not.

Hi SGayleC,
It appears that your iCloud account on your Mac is still associated with the old email address. On your Mac, In System Preferences, are you able to click on iCloud and sign out of your old account? If so, you should then be able to sign in with your correct Apple ID and password.
I'm including some information on this below, and a link to our Apple ID support team if you need it.
OS X Yosemite: If you sign out of iCloud
http://support.apple.com/kb/PH18999?viewlocale=en_US
OS X Yosemite: If you sign out of iCloud
If you sign out in iCloud preferences, your iCloud mail, calendars, reminders, notes, and documents stored in iCloud are removed from your Mac. If you have photos in My Photo Stream that aren’t imported, they’re removed from your Mac. Your bookmarks and Reading List remain in Safari, but the iCloud Tabs list of webpages open on your other devices is no longer available.
When you sign out of iCloud, you’re asked whether you want to keep a copy of the data for Contacts and Safari passwords. If you keep copies of the iCloud data, iCloud doesn’t keep the copy up to date with changes on your other devices.
Copy iCloud documents and data before signing out
Before signing out of iCloud, you can copy or archive iCloud documents and data to your Mac.
iCloud Drive: For instructions on copying documents to your Mac, see Store documents with iCloud Drive.
Documents and data you copy to your Mac aren’t kept up to date with changes on your other devices.
After signing out of iCloud on your Mac, you can still access your iCloud documents and data on your other devices set up for iCloud and on iCloud.com. If you sign in to iCloud again on your Mac, your iCloud documents and data reappear on your Mac.

My mail icon in my dock tells me i have 29 messages not read inbox even when i have no messages in my inbox. how do i get rid of that aggravating number?

my mail icon in the dock tells me i have an incorrect number of messages that i haven't read. it continues to say 29 in the read circle even if my inbox is completely empty. how do i make unread messages an accurate number?

Restart your Mac.

I have been taken over by "installmac" how do I get rid of it?

Help...."installmac" wont get off my computer

You installed the "Genieo/InstallMac" rootkit. The product is a fraud, and the developer knowingly distributes an uninstaller that doesn't work. I suggest the tedious procedure below to disable Genieo. This procedure may leave a few small files behind, but it will permanently deactivate the rootkit (as long as you never reinstall it.)
Malware is constantly changing to get around the defenses against it. The instructions in this comment are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.
Back up all data. You must know how to restore from a backup even if the system becomes unbootable. If you don't know how to do that, or if you don't have any backups, stop here and ask for guidance.
Step 1
In the Applications folder, there should be an item named "Genieo". Select it and open the Finder Info window. If it shows that the Version is less than 2.0, download and install the current version from the genieo.com website. This may seem paradoxical, since the goal is to remove it, but you'll be saving yourself some trouble as well as the risk of putting the system in an unusable state.
There should be another application in the same folder named "Uninstall Genieo". After updating Genieo, if necessary, launch "Uninstall Genieo" and follow the prompts to remove the "newspaper-style home page." Restart the computer.
This step does not completely inactivate Genieo.
Step 2
Don't take this step unless you completed Step 1, including the restart, without any error messages. If you couldn't complete Step 1, stop here and ask for instructions.
Triple-click anywhere in the line below on this page to select it:
/Library/Frameworks/GenieoExtra.framework
Right-click or control-click the line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.
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 won't see what you pasted because a line break is included. Press return.
A folder should open with an item named "GenieoExtra.framework" selected. Move that item to the Trash. You'll be prompted for your administrator password.
Move each of these items to the Trash in the same way:
/Library/LaunchAgents/com.genieo.completer.update.plist
/Library/LaunchAgents/com.genieo.engine.plist
/Library/LaunchAgents/com.genieoinnovation.macextension.plist
/Library/LaunchDaemons/com.genieoinnovation.macextension.client.plist
/Library/PrivilegedHelperTools/com.genieoinnovation.macextension.client/u/usr/lib/libgenkit.dylib/usr/lib/libgenkitsa.dylib
/usr/lib/libimckit.dylib
/usr/lib/libimckitsa.dylib~/Library/Application Support/com.genieoinnovation.Installer~/Library/LaunchAgents/com.genieo.completer.download.plist
~/Library/LaunchAgents/com.genieo.completer.update.plist
If there are other items with a name that includes "Genieo" or "genieo" alongside any of those listed above, move them as well. There's no need to restart after each one. Some of these items will be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
Restart and empty the Trash. Don't try to empty the Trash until you have restarted.
Step 3
From the Safari menu bar, select
Safari ▹ Preferences... ▹ Extensions
Uninstall any extensions you don't know you need, including ones called "Genieo" or "Omnibar," and any that have the word "Spigot" or "InstallMac" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
Your web browser(s) should now be working, and you should be able to reset the home page and search engine. If not, stop here and post your results.
Make sure you don't repeat the mistake that led you to install this software. Chances are you got it from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad has a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If youever download a file that isn't obviously what you expected, delete it immediately.
You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the Genieo developer has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing, has not done so, even though it's aware of the problem. It must be said that this failure of oversight is inexcusable and has seriously compromised the value of Gatekeeper and the Developer ID program. You cannot rely on Gatekeeper alone to protect you from harmful software.
Finally, be forewarned that when Genieo is mentioned on this site, the developer sometimes shows up under the name "Genieo support." If that happens, don't believe anything he says, but feel free to tell him what you think of his scam.

My week old MacBook w/ retina has half of its storage taken up by the "other" category. I don't have any downloads or backups. How can I get rid of it?

I now no longer have any storage and it is only 1 week old!!

For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.

I have two Apple ID's. How do I get rid of one?

I have two Apple ID's. One is my real Apple ID that I use for everything, and one I don't use and I don't know why it got created. How can I have the extraneous Apple ID deleted?

Just never use the bogus ID again. It will die a natural death.
