    Post a screenshot of Activity Monitor and provide the machine's model and which OS it's running. iMac and null are useless tidbits.

    You installed one or more variants of the "InstallMac" trojan. Take the steps below to disable it.

    The criminal behind this attack tries to make the malware hard to remove by varying the names of the files it installs. 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.

    Back up all data before continuing.

    1. 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. You won't see what you pasted because a line break is included. Press return. A folder named "LaunchAgents" will open.

    2. Inside the folder you just opened, there may files with a name of the form

              something.download.plist

              something.ltvbit.plist

              something.update.plist

    where something is usually a meaningless string, such as any of the following:

              InKeepr

              InstallMac

              Javeview

              Leperdvil

              Manroling

              Otwexplain

    These are examples, not a complete list. The string could be anything. The point is that the same string will appear in the name of three files.

    You could have more than one copy of the malware, with different values of something.

    Move all such items to the Trash. There may not be any other files in the LaunchAgents folder; in that case, you can delete the folder, but otherwise don't delete it. Other files in the folder are not necessarily malicious (though they could be, if you also installed some other kind of malware.)

    Log out or restart the computer. The trojan will now be inactive, but there are a few more components of it that should be cleaned up.

    3. Open this folder in the same way as above:

    ~/Library/Application Support

    and move to the Trash any subfolders named with the same something you found in Step 2.

    Don't move the Application Support folder or anything else inside it.

    4. Open the Applications folder. If there is an item with the same name as in Step 3, or any of the other names listed in Step 2, drag it to the Trash.

    If in doubt, press the key combination option-command-4 to arrange the apps by date added. Look at the apps that have been added since you first noticed the problem. If there is one you don't recognize, drag it to the Trash.

    Empty the Trash.

    If you get an alert that the application is in use, force it to quit.

    5. From the Safari menu bar, select

              Safari Preferences... Extensions

    Uninstall all extensions you don't know you need. If in doubt, remove all of them. None is required for normal operation. Do the equivalent in the Chrome and Firefox browsers, if you use either of those.

    6. Reset the home page in each of your browsers, if it was changed. In Safari, first load the home page you want, then select

              Safari Preferences... General

    and click

              Set to Current Page

    Thanks for your suggestion but have now done the following:

     

    Rang Apple and was talked through the following:

     

    Safari preferences; under Privacy click on 'Remove All Website Data' > under Extensions we found removed Genio (the infiltrator) and removed that

     

    Then under Advanced make sure 'Show Develop menu in menu bar' and the click on Develop in tool bar and click on Empty Caches.

     

    Cleared browser history in Firefox as well. Open browser click on 3 bars on top right, click on History, click on Clear recent history and then tick everything in dialogue box (you can un-tick the ones that you added the tick to later) and then click Clear everything.

     

    Download  Malwarebytes Anti-Malware for Mac (free 3rd party software) and run. This found the culprit in a minute or less. Cleared out what it found.

     

    Restarted computer sand ran Malwarebytes again = Clear

    Nothing on this thread has managed to work for me. I have done everything down to the finest detail and it isn't working. Does anyone have any other ideas, I'm about at my wits end with this problem, I haven't been able to fix it in months! The entries have began to change from AppTS to AppNOS, if thats any help. I can't download antivirus software for various reasons. I'm desperate! Please someone have an answer please

    Why not just ring Apple as I did. I did no use Linc's suggestion as it was very long-winded and in the end it was simple to sort out with what I did and described above but it was Apple who steered me through it. Good luck. Also it may depend on whether those entries should or should not be there in the first place? So, is your computer running fine anyway? Talk to Apple and get to one of their senior techies if possible on the phone.
