Another free offering from Microsoft, the Microsoft Security Essentials is a decent Antivirus software which has already gathered good reviews from different websites. The antivirus is lightweight at just 8 MB, has scored as high as 96% in malware detection & doesn’t affect your computer’s performance. The downfalls are that you need a genuine copy of Windows to install this software & the scanning of removable drives is disabled by default. Also the software might refuse to get installed if your computer is already infected by a virus.
