If you love freebies, I guess you know about Microsoft Security Essentials. This antivirus software is Microsoft’s answer to expensive computer security tools that are swamping the software market today. Microsoft Security Essential or MSE is a totally free software. It has just came out of its beta stage and is now available for download. It is available for Windows XP, Vista, and the new Windows 7. Though it is a freeware, it can do a lot of things that paid antivirus software can do like real-time monitoring of your system, protection from viruses, malwares, and other malicious software.
If you are using a pirated version of the Windows operating system, never mind trying to download it because you will not be able to install it. That’s what I know, I haven’t tried installing it on a PC that runs pirated Windows OS.
