Unable to reinstall Mac Home AV free ed

greiggy

I have used this successfully for a while, but the upgrade to Mavericks and 9.1 seems to have killed it. The auto-update became sporadic and then gave continual authentication errors. It did manage to complete a scan, but the progress window showed otherwise. All a bit flaky.

I decided to remove it with AppZapper and reinstall. The installer runs, but it quits with an "unable to install" message. What is the wisdom on this?

    It's not recommended to use a third-party uninstaller.  The way to uninstall is explained in this post: Remove (uninstall) Sophos Anti-Virus for Mac Home Edition (the free version).

    How exactly did you uninstall (or 'zap') it with AppZapper?  I presume you drag one or more files to AppZapper?  Just one?  Which one?

    I dragged the main app and AppZapper locates all the various application support files and trashes them. It usually does a very clean job.

    I used the Sophos removal tool to remove it again and attempted to re-install. I just get a window that says:

    "The installation failed. The software was not installed successfully. Remove the software and re-install."

    What next?

    I just tested this and though the Sophos Anti-Virus app icon doesn't display correctly (after reinstalling) it seem to work - see the demo video below.  Did you move any other files?

    Try a reboot and then try to reinstall again.  You you still have the 'Remove Sophos Anti-Virus' app in your Applications folder?  Can you run that?

    Important:  If possible, posting a screenshot of the problem would help for context.

    A reboot fixed the icon.  FYI: All OK from my testing so far.

    Still struggling with this.

    Have uninstalled using the Sophos uninstaller, secure emptied the trash, rebooted, attempted to reinstall. A few attempts now. I get the same "Failed to install' message.

    I notice that the menubar icon is still appearing despite all the uninstalls...

    You could try the removal script.  This post mentions it.

    After a restart, I ran the terminal script as recommended (referenced below).

    I got the response: "No such file or directory"

    What now?

    cd /Library/Sophos\ Anti-Virus/
sudo ./remove_v9.sh

    You mean the folder for Sophos Anti-Virus is no longer there and hence you don't have the script?

    I've (hopefully) attached it below.  Save it to your desktop.  You'll need to change the file extensions from .sh.txt to just .sh...

    Then open Terminal and run as described before.  It should look like this...

    I downloaded script to desktop, changed suffix to .sh exactly as you helpfully showed.

    Attempted to run the sudo command in Terminal. Entered mu usual login password. It returned a 'Command not found':

    I'm not that experienced in the area of sheel commands -- what am I doing wrong?
