Note: Only for legitimate users of Windows XP/Vista/7.
If you are tired of paying for Anti-Virus software for your computer, the day has finally come when you no longer have to pay for it. Microsoft has released their own anti-virus program for all windows users (with legit copies of windows), probably to compete with apple. The software is called Microsoft Security Essentials (MSE), and will most likely be free forever (updates and all). The software is available for XP (32-bit) and both Vista and Windows 7 (32- and 64- bit).
Now before installing MSE you must first uninstall the current anti-virus software you use. Before uninstalling the program, it's features must be shut-off as they are typically designed to protect themselves from removal. In order to do this, move your mouse to the bottom right corner of your screen. Double click on the icon for your anti-virus software (for MSE this is a little house). This will open a control screen for your software. On this screen uncheck or disable all features of your anti-virus software, there will likely be warnings against proceeding - disregard these. Next we will uninstall the program, this can be done by gone within the control panel: click on "Start" then "Control Panel", click on the "Add or Remove Programs" link and then navigate to your anti-virus software. Always remove peripheral components first (i.e. for Symantec products remove the LiveUpdate or anti-malware feature first) followed by the main component (i.e. for Symantec products this would be the symantec anti-virus module). You may have to restart several times during this process, you should always restart when prompted. Once you have removed all of the programs labeled with the maker of your anti-virus software your computer will be ready to install MSE.
Now we can go ahead and begin the MSE installation process. The installer can be found at the following website: http://www.microsoft.com/security_essentials/
Be sure to choose the correct version of the software: select the "Download Now" button, and click on the link corresponding to your operating system. This will initiate a download, when the file has saved to your computer, double click on the installer and follow on-screen instructions to installing MSE. Updating the product immediately and then promptly running a system scan is highly recommended.
Enjoy free anti-virus software for life!! Another interesting fact...according to an independent rater of anti-virus software, Virus Bulletin, MSE is one of the very best with a VB100 rating: http://www.virusbtn.com/vb100/archive/results?vendor=VE70
