Before we tell you more about what Microsoft antivirus software is called and how it works, here is some information you might find useful. Microsoft antivirus software can be used by small businesses for up to 10 PCs! That being told, let’s look closely at what the Microsoft antivirus software is capable of doing and how you can get it installed on your PC. However before that, it’s time for another update: Microsoft Antivirus software is free!

Yes, Microsoft antivirus software called Microsoft Security Essentials is free for up to 10 computers. For more, you need to buy the premium antivirus package called Microsoft Forefront Endpoint Protection.

What Makes Microsoft Antivirus Software So Special

Called the dynamic signature service, Microsoft deploys this technology to keep its antivirus program to run in real time and keep viruses away without needing to download signature updates, something that all other leading anti-viruses need. Without an internet connection and absence of updates download, they appear feeble to viruses attack. Microsoft antivirus software doesn’t download any file, rather stays updated through this technology. Another highlight is it offers real time protection. It protects PCs from viruses, malware, spyware, and other malicious software. Microsoft Security Essential doesn’t consume much processing power as well and runs in the background. There are no delays or slow responses in regular computing. When the software runs in Green, it denotes that your PC is good.

System Requirement

Here is what you would need on your PC to run the software:

• (Service Pack 2 or Service Pack 3) Genuine Windows XP, (Gold, Service Pack 1, or Service Pack 2) Genuine Windows Vista, Genuine Windows 7
• For XP: CPU clock speed- 500 MHz or higher, 256 MB RAM or higher
• For Vista: CPU clock speed- 1.0 GHz or higher, 1 GB RAM or higher
• For Windows 7: CPU clock speed of 1.0 GHz or higher, 1 GB RAM or higher
• 200 MB of available hard disk space

Before installing the antivirus software, you need to ensure that there are no other antivirus software on the PC. If yes, take them off and then install this or there might be software conflicts. The only challenge that Microsoft Security Essential has faced is that its virus detection technology has been compared with OneCare, earlier antivirus software by Microsoft. For premium antivirus programs, Windows Security Essential is no reason to bother, something agreed by Microsoft itself at the time of launching their product. That being said, it is a decent replacement for paid antivirus software if your computer doesn’t have one or you don’t have much data to bother about.
