Chinese search engine Baidu has launched a free antivirus program named Baidu Antivirus 2013. The company claimed it as an ultra light weight, easy to use, extremely fast anti-virus program that promises to protect your system from malware, viruses, spyware, adware and other malicious programs. 
The main thing I noticed is its user interface, it is simple, elegant, easy to use and more over it has a clutter free interface. It is is compatible with a wide variety of operating systems from Windows XP to Windows 8. Also setup file is only 11MB and it takes less than 1 minute to completely install.
The program uses three different engines – Engine Baidu Antivirus, Avira Antivirus Engine and Baidu Cloud Security Engine. This ensures complete protection from all online threats, and effectively finds infected files on your computer.
