Uninstall Intego Virus barrier

"Virusbarrier is in use"

Go to your accounts preferences for your user and disable this item in login items. You may need to restart to quit the application, or it is possible that thing may be visible in the "Force quit" menu under the Apple Finder menu.

Seems I must find that plugin

Click once on the Spotlight item and hover the mouse over it. A window will appear showing the path to the item.

Another thing I clicked on my home icon in finder and all i get are all my Office files.Seems that to find Library etc i must now click the HD icon.This has ocurred since i backed up all my userfiles.Maybe I should have backed all the files

This is very strange and disturbing. There is a Library in your System folder, but it is not the same one as in your user area. The one in your user area contains lots of settings and files related to your use of certain programs. My user area also has lots of other folders such as documents, music, etc. Unless you trashed those they should probably also be there.

Here's my boilerplate response to uninstalling. In particular note the section on login items:

First, I suggest backing up your drive in case you uninstall something you shouldn't have uninstalled.

Most small programs can have all their components contained within an app package. After running, the program will likely install a file in Preferences (either in your user area, or the main preferences, or both). Dragging a program and its preferences to the trash is often all that is needed, or you can use a program like AppDelete to delete these programs. However, most app delete programs will not have an inventory of what is installed -- they just look for files that are clearly associated with the app you are deleting.

Try to find files associated with the application you want to delete by using Spotlight, Finder, or EasyFind (free and generally highly recommended) to search for the application's name. Favorite folders for files to be installed are:

/Applications/
/Library/Preferences/
/Users/ YourName/Library/Application Support/
/Users/ YourName/Library/Preferences

where YourName refers to the user name when you login and the / indicates the series of folders down from your main drive.

A few programs may set login items to start automatically when your computer starts or a specific user logs in. These items are located in: /Library/StartupItems/ or /Users/YourName/Library/StartupItems/ To edit these, go to your account set up in System Preferences, login items tab, select the item(s) and a "-" to remove.

More involved programs (e.g., Office) may install bits and pieces all over the place, like fonts, libraries, etc. The software installer may have an uninstall option, or there may be a separate uninstaller for these. In bad situations you have to hunt around yourself.

Some programs install invisible files. You can use a utility like Onyx to toggle visibility on your computer and check for invisible files.

Sometimes programs install files (often hidden) not readily associated with the program and if you're worried about those the only thing to do is a scan before and after installing a program and see what has changed.

Check out the utility [AppDelete|www.apple.com/downloads/macosx/system diskutilities/appdelete.html]. It will remove simple applications and most of their associated files.

There should be an uninstaller included with the software. Check the documentation on how to properly uninstall the software. Many anti-virus programs install background programs that provide the scanning of new programs or files downloaded or installed on the computer. Dragging the main application to the Trash does not remove them.

If you can't find the uninstaller or one wasn't included then you need to hunt for these items on your hard drive. 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. Most applications create preference files which 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 located 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.

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.

There are also several shareware utilities that can uninstall applications:

AppZapper
CleanApp
Yank
SuperPop
Uninstaller
Spring Cleaning

Look for them at VersionTracker or MacUpdate.

For more information visit The XLab FAQs and read the FAQ on removing software.

Spotlight does not find files in the system folders by default. I would suggest you download the freeware utility, Easy Find, for the task - VersionTracker or MacUpdate.
