Free Antivirus for Windows 7: Microsoft Security Essentials

If we are not used to seeing free programs at Microsoft, we can welcome the free antivirus software offered for Windows operating systems. Released in September 2009, Microsoft Security Essentials (MSE) is a free antivirus protection software that was then available on Windows XP, Vista and 7. Since then, Windows 7 is the only survivor since it is the only version still maintained by Microsoft. On Windows 8, 8.1, and 10, Security Essentials is replaced by Windows Defender, the new name for Microsoft’s free antivirus.

Microsoft Security Essentials is a free antivirus program to protect a Windows 7 computer. This anti-virus is therefore not chargeable, it works in french and it is not necessary to renew it every year (like Avast, for example). So no need to pay for an antivirus Kaspersky, Norton, BitDefender or McAfee since Microsoft generously offers a good tool to neutralize and eliminate viruses and other malware.

You should not have multiple antivirus software on the same machine. To install MSE, you must first uninstall the old virus protection program and then install the Microsoft software.
