MacDefender – New virus for Macs, How to Prevent or Remove

Up until recently, Mac users have been able to enjoy fairly smooth sailing when it comes to worrying about viruses. As PCs (Windows machines) have been the more popular choice of the computing market, virus creators typically target PCs for their devious creations. Unfortunately, a few weeks ago, a new virus called MacDefender was released specifically targeting Macs.

MacDefender (aka MacProtector or MacSecurity) is a phishing scam designed to get your credit card information. The scam redirects a web browser to pages which claim your computer is infected with a virus which can only be removed by downloading MacDefender. Here our a few steps to help prevent MacDefender from infecting your computer.

1. Open Safari and select Preferences from the Safari menu. On the General tab, remove the check from Open “safe” files after downloading. The virus is thought to be taking advantage of this default Mac setting when possible. Safari’s preferences also control how other browsers (Firefox, Chrome, etc.) work so disabling this setting will also help protect your computer when using other web browsers.

Disable "Open "safe" files after download"

2. If you are redirected to a page which says you have a virus or you think might be a click or two away from getting the virus, force quit your browser immediately. Force quitting will hopefully stop the virus from installing. To perform a Force quite, hold down the the Option, Command and Esc keys. Select the application you would like to close and click Force Quit.

3. If you have contracted the virus, here are some steps to remove the virus from your computer:

a. Move or close the Scan Window
b. Go to the Utilities folder in the Applications folder and launch Activity Monitor
c. Choose All Processes from the pop up menu in the upper right corner of the window
d. Under the Process Name column, look for the name of the app and click to select it; common app names include: MacDefender, MacSecurity or MacProtector
e. Click the Quit Process button in the upper left corner of the window and select Quit
f. Quit Activity Monitor application
g. Open the Applications folder
h. Locate the app ex. MacDefender, MacSecurity, MacProtector or other name
i. Drag to Trash, and empty Trash

Malware also installs a login item in your account in System Preferences. Removal of the login item is not necessary, but you can remove it by following the steps below.

a. Open System Preferences, select Accounts, then Login Items
b. Select the name of the app you removed in the steps above ex. MacDefender, MacSecurity, MacProtector
c. Click the minus button

Mac may be New to You and Me

I just switched from Windows to Mac.  Now what?  I was counting on no adjustment to a different computer.  I didn’t know what I needed to know; I couldn’t even begin to ask the right questions.  So here I am with my shiny new Mac.  Now what?

When someone showed me the power button at the lower back of the computer that was at least a start; I know how to turn the computer on.  I felt pretty encouraged when I saw the beautiful screen.  Colors seem super vivid.  Apple says the screen is backlit and has an enormous number of pixels.  This means that I’m looking at a screen that’s even sharper than an HD TV.

Sure is pretty, but where are my documents?  Well, I’m told that I can use the externals that I was already accustomed to using such as my USB flash drive.  I can plug my flash drive, for example, into the USB port in the back.  An icon will show on my Desktop and I can double-click to open any file.  My external hard drive that I bought to back up files, to transport really large files and for extra storage will work well via the Firewire port located on the back.  Files can be copied onto the Desktop simply by dragging them.  I could drag them into folders that I create either on the Desktop or in the Document folder on the Desktop.

What about my files on the “H” drive (It’s the Home drive on a Mac.)?  How do I access those using my new Mac?  This task takes a few steps but only the first time.  Here goes.  Click on the Go menu.  Select Connect to Server.  Choose from the list or type the name of your server.  For example, ITS staff would type “admin3.smith.edu.”  Click OK.  Now, log on with your username and password.  Good.  You’ll see that an icon has mounted on the Desktop.  Double click and in the directory window you will be able to navigate to your “HOME” location on the server and then your personal folder that has your username on it.  To avoid many steps each time that you want to reach your Home drive, drag your new Home drive icon to the Dock.  When you want to access your files on your Home drive then click on the icon on your Dock.  Log in.

The Dock is a fancy bar at the bottom of the screen that “docks” my most likely to be used applications (software).  I can add more applications by dragging an icon onto the Dock and I can delete the ones displayed by dragging an icon off the Dock.  That is, I can add or delete the icon for an application simply by dragging and dropping.  The Dock has a second purpose of holding an icon for each of my open and minimized windows.  These will always appear at the right end of the Dock.  And, one more thing:  I can click on the icon on the Dock for each of my open applications in order to switch from one to the other.

Of course, I discovered that there is no “My Computer” on a Mac, however; if I double click on my Macintosh HD icon in the upper right corner of the Desktop, I’ll see the Finder directory that reminds me very much of Windows Explorer (the Windows directory).

One of the first things that I noticed about my Desktop was that it had a folder called Documents.  It’s just like old times with My Documents on my Windows-based computer.

Trash is still Trash.  I can drag icons or files or folders to the Trash which sits on the right end of the Dock.  Empty the Trash by clicking on the Trash icon or by going to the Apple menu and selecting “Empty Trash.”

I used to change time, display and other settings on my PC from my Control Panel.  I can do the same by going to the Apple menu and choosing System Preferences.

There is so much more to tell, of course, but all the information about what’s alike and what’s different about a Mac compared to a Windows machine is extremely simple and easy to understand.  I recommend viewing the brief video tutorials at apple.com:
