Microsoft Security Essentials Upgrade – Upgrading the AntiMalware
Speaking of Microsoft Security Essentials Upgrade, you have two options: 1) download the latest version installer from the Microsoft website, remove the current one and install the one you downloaded; and 2) upgrade to latest version smoothly using the current, installed MSE version. If you still have the beta version of the MSE, I would recommend you to use the first method for Microsoft Security Essentials Upgrade as people reported many problems while upgrading to MSE latest version using the in-place upgrade.
As of March 22 of 2010, the latest version of MSE stands 1961. Though plenty of third party websites also offer the latest version, I strongly urge that you use the Microsoft website to download and install Microsoft Security Essentials. This is because some rogue software, a lookalike of MSE is doing rounds on the Internet, which if installed by accident or ignorance, creates much problem. It is hard to uninstall Security Essentials 2010, the lookalike rogue software. While researching MSE for any purpose, make sure you type "Microsoft Security Essentials" and not just "Security Essentials" else you get the malware instead of Microsoft's antimalware.
Coming back to Microsoft Security Essentials Upgrade, if you still have the beta version, use the Add/Remove Programs (in Control Panel) to remove the antimalware. Thereafter, download the latest version of MSE from Microsoft only. Make sure you remove all other antivirus and antispyware before installing the MSE. If you face any problems installing MSE, please read our article on MSE Installation Error.
If you already have a stable version of MSE and wish to proceed with Microsoft Security Essentials upgrade, you can proceed as follows:
Double click the MSE icon in the taskbar to open it. On the Home tab, you will find the Help drop down menu towards right corner below tabs. Click on the black triangle below Help and select Upgrade Microsoft Security Essentials.
The Microsoft Security Essentials Wizard appears as shown below. Click Upgrade.
The Wizard searches for the latest version of the MSE and installs it. This may take few minutes.
To check if you have the latest version, click on the Help menu again and click on About Microsoft Security Essentials. You will get an information window as shown below. It indicates the version of MSE that is currently installed on your computer.
Using this method, you can always have a smooth Microsoft Security Essentials Upgrade. This method is also the safest method to upgrade MSE as the Wizard won't download any kind of lookalike software such as the Security Essentials 2010 mentioned above.
