How to get rid of Trojan malware on OS X

`My son downloaded a movie app and it seems to have infected my Imac with this Trojan Malware, rendering it impossible to use. Adverts popping up ALL the time and it's just ridiculously slow. My emails are now also 90% spam...I've backed everything up but really don't know what to do next? Shall I take it to an apple store or attempt to clean it myself? Any advice greatly appreciated. Ute

You inadvertently installed adware. It's not necessary to bring your Mac to an Apple Store, and you do not need to download or install anything to fix it.
For a description of how this may have occurred, how to avoid it in the future, and for Apple's recommended actions read How to install adware. Apple's instructions are linked in the Recovery Procedure near the end of that document. Read and follow them carefully. Pay particular attention to the easily overlooked passages directing you to restart your Mac when required.
You'll invite spam by divulging your email address on a public forum. Other than that learn about how to manage junk mail by reading these Apple Support documents:

Anyone no how to get rid of mackeeper malware

idownloaded mackeeper as it said recommend by apple wish i didnt
does anyone on how to get rid of the malware that c
downloaded with it please

"MacKeeper" is a scam with only one useful feature: it deletes itself.
First, back up all data.
Note: These instructions apply to the version of the product that I downloaded and tested in early 2012. I can't be sure that they apply to other versions.
If you have incompletely removed MacKeeper—for example, by dragging the application to the Trash and immediately emptying—then you'll have to reinstall it and start over.
IMPORTANT: "MacKeeper" has what the developer calls an “encryption” feature. In my tests, I didn't try to verify what this feature really does. If you used it to “encrypt” any of your files, “decrypt” them before you uninstall, or (preferably) restore the files from backups made before they were “encrypted.” As the developer is not trustworthy, you should assume that the "decrypted" files are corrupt unless proven otherwise.
In the Finder, select
Go ▹ Applications
from the menu bar, or press the key combination shift-command-A. The "MacKeeper" application is in the folder that opens. Quit it if it's running, then drag it to the Trash. You'll be prompted for your login password. Click the Uninstall MacKeeper button in the dialog that appears. All the other functional components of the software will be deleted. Restart the computer and empty the Trash.
☞ Quit MacKeeper before dragging it to the Trash.
☞ Let MacKeeper delete its other components before you empty the Trash.
☞ Don't try to drag the MacKeeper Dock icon to the Trash.
☞ Don't try to remove MacKeeper while running in safe mode.

How ndo get rid of tuneupmymac malware that loaded with firefox???

I downloaded firefox onto my new mac mini and got the malware tuneupmymac and reset search (with a cardboard box icon ).
I trusted Mozilla, didn't expect malware to come with it. How do I get rid of them? Putting them in the trash doesn't work.
Thank you,
newtom

hello newtom, i don't know where you've downloaded it from, but original mozilla builds form mozilla.org will never come with such crap or bundled software.
in order to address the issue you might want to [[Reset Firefox – easily fix most problems|reset firefox]] and for further steps see the following articles:
*[[Remove a toolbar that has taken over your Firefox search or home page]]

How to get rid of "Trojan.AutorunINF.Gen" ?

I caught a trojan via my workplace (PC) all via my USB key.
It is called "Trojan.AutorunINF.Gen" or "W32/HostInf-A".
How do I get rid of?
Thank you.

You might try doing a Google search on how to remove it from a Windows machine. Perhaps you will find instructions for a manual removal.
You can search your machine for any files associated with the name of the trojan. Not quite sure what else you can do about it. See the following:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
    1. AppZapper 2.0.1
    2. AppDelete 3.2.6
    3. Automaton 1.50
    4. Hazel
    5. AppCleaner 2.1.0
    6. CleanApp
    7. iTrash 1.8.2
    8. Amnesia
    9. Uninstaller 1.15.1
10. Spring Cleaning 11.0.1

How to get rid of this Malware

A few days ago I down loaded something something off the internet and now my computer is going crazy with pop-ups and and redirects to different sites. I have tried to to reset all browser settings deleted all cookies hoping that would work but still no luck. Even on Google, every time I search for something I get the yellow add links that were never there before when searching in google. I understand this is a malware problem and the same thing is happening for every browser I used. I ran antivirus software, still says its clean. I am scared to login to any of my accounts for I feel like my computer is at risk. PLEASE HELP!!

You may have inadvertently installed adware. Eradicating it is simple. For an explanation or how this may have occurred, how to avoid it in the future, and for one possible solution read How to install adware.
I ran antivirus software, still says its clean.
Your question was posted in the Classic Mac OS (OS9, OS8 & System 7) forum, and if that is in fact what you are running, please clarify. Assuming you are running a recent version of OS X and not a fifteen+ year old "classic" Mac OS, anti-virus software is useless. Whatever you installed, get rid of it.

How to get rid of AdChoices malware?

I have reset Fierfox several times and cleaned up the file systems using Avast app. But the malware is still there and I get this unwanted adds popping up when I browse websites. My Macbook got infected when I downloaded a free software to improve video streaming and since than a nightmare with AdChoices started. I got rid of that free software but an extension called Cinema + Plus which was installed along with the free software remains in the Extensions tab. I disabled it but can't remove permanently because there is no remove button. Not even resetting of Firefox from Troubleshooting tool got rid of this extension. Appreciate if someone can suggest how to solve this issue. Thanks!

How to get rid of a malware program - iMunizator

I picked up a malware from somewhere and now I cannot get rid of it. Any suggestions.
Thanks in advance

iMunizator is a repackaged MacSweeper and is nothing but "scareware". First, run Activity Monitor and look for the "iMunizatorDaemon" process and force-quit it. That should allow you to quit and trash the iMunizator application. Then look in this folder:
youruser -> Library -> Contextual Menu Items
and delete the iMunizatorCMI.plugin file.
Finally, do a Finder search (Command-F from Finder), setting it to search system files - pull down the menu that says "Kind" to System files and set to "include" - for "iMunizator" and delete all the preference and cache files you find.
That should clear that junk off your system.
Hope this helps.
P.S. Note that the only way to acquire this malware is for a user to download and run it him/herself. It cannot spread to your computer by itself. So for the future, be very careful about what you download and run on your computer, particularly anything that purports to "scan" or "tune up" your system.

How to get rid of adware/malware? It turned into a nightmare.

Hi everyone,
This is my first post here so I hope I am posting on the right place. So basically I am using a Macbook Pro with Retina Display (13 inch) and it was bought on September 2014. This is all I know about my laptop as I really don't understand from softwares or anything of that kind (I do not even know what IOS means, sorry!) and I cannot look at any of the information because it was a gift from my father who lives in another country!
Now, the problem is that I do not know whatever happened, as I do not download anything to my laptop other than university slides and lecture notes. But since yesterday, almost whenever I click on a legit website, the website is replaced by this weight loss advertisement (or malware, I do not know the word to use as I have just learnt about these terms while looking for a solution to my problem) within a few seconds. This is a nightmare, and I am really really happy at least it did not happen on this website.
Do you know what I should do? Sorry I can't provide any information as I don't know anything about technology myself.
Any help is greatly appreciated, thank you very much!

Click here and follow the instructions, or if they don't cover the type of adware 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.

Firefox has a False Ebay shopping site Tab that keeps opening up. Please tell me how to get rid of it/Malware and Bitdefender have not stopped it.

Tab opens up every time I surf a web site. It is obviously malware but, both Bitdefender TS 2015 and Winzip malware programs dont see it.
please help.
Regards, Ron

hello, if you suspect that you have adware/malware present, please perform all these steps:
# [[Reset Firefox – easily fix most problems|reset firefox]] (this will keep your bookmarks and passwords)
# afterwards go to the firefox menu ≡ > addons > extensions and in case there are still extensions listed there, disable them.
# finally run a full scan of your system with different other security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner] to make sure that adware isn't present in other places of your system as well.

How to get rid of malware on Mac Pro

I have a Mac Pro with the OS X Yosemite. My computer has malware on it. I keep getting popups and ads on my screen, whether I'm using Safari or Chrome. One of the popups says "Suspicious activity found on your computer, due to pop-up advertisement windows and invasive links. Please contact tech support at 1-866-215-6348." I want to know how to get rid of this malware. Thanks in advance.

Some are persistent. Force quit Safari again. Disconnect from the Internet by either turning off Wi-Fi in the System Preferences, or unplugging the Ethernet cable from your router/modem. Hold the Shift key and launch Safari again. If the same popup appears, you will be able to dismiss it and navigate away from the page, or close its tab. Reconnect to the Internet.
Though reading your initial post again, it's sounding more like JimmyCMPIT is correct since you're seeing ads in multiple browsers. It's just rare for one the ads that pops up to be like one of the tech support scams.
In which case, you can either follow Apple's manual instructions for removing adware, or use the free automated tool, AdwareMedic (as mentioned by, and linked to by Jimmy).
It should be noted that Apple's manual removal instructions are typically outdated. Sometimes a lot outdated. It depends on when Apple last updated their instructions page. If you would prefer to manually remove the adware on your system, you can find much more up-to-date instructions on The Safe Mac's adware removal page.

Any ideas?

You installed the "DownLite" trojan, perhaps under a different name. Remove it as follows.
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.
Triple-click anywhere in the line below on this page to select it:
/Library/LaunchAgents/com.vsearch.agent.plist
Right-click or control-click the line and select
          Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item named "VSearch" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
Repeat with each of these lines:
/Library/LaunchDaemons/com.vsearch.daemon.plist
/Library/LaunchDaemons/com.vsearch.helper.plist
/Library/LaunchDaemons/Jack.plist
Restart the computer and empty the Trash. Then delete the following items in the same way:
/Library/Application Support/VSearch
/Library/PrivilegedHelperTools/Jack
/System/Library/Frameworks/VSearch.framework
~/Library/Internet Plug-Ins/ConduitNPAPIPlugin.plugin
Some of these items may 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.
From the Safari menu bar, select
          Safari ▹ Preferences... ▹ Extensions
Uninstall any extensions you don't know you need, including any that have the word "Spigot" or "Conduit" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
This trojan is distributed on illegal websites that traffic in pirated movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect much worse to happen in the future.
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 DownLite 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. This failure of oversight is inexcusable and has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.
*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.

How do i get rid of trojan.generic.554705?

My virus protection scan found trojan.generic.554705 but doesn't tell me how to get rid of it. How can I get rid of it?

That's not Mac malware, it's a generic signature for a Windows trojan. Most likely, this is attached to an e-mail message or something like that. What file does BitDefender report as being "infected?"
Note that BitDefender did not do very well at detecting Mac malware back in January, when I tested 20 different anti-virus programs. I would not recommend using it.

How do I get rid of this malware and make my computer go back to normal?
