Not My Fault (AKA: NotMyFault) is a driver-level system debugging tool, developed by Microsoft's Sysinternals group, used to artificially make system crash, memory leak, frozen screen and blue screen in order to reconstruct, analyze and debug the potential problems in a computer.

Today's viruses, trojans and many other malicious software are much smarter and more shrewd than ever before. In other words, the traditional methods of identifying suspicious processes such like by checking the startup items have been far from enough. For example, they have been used to embed themselves into system processes, inject into driver files, disguise as system services, and so on, so as to implement autorun and bypass the scanning and killing of most anti-virus software. As a consequence, we could see that more and more antivirus software AIDS came into popular.

As is known to all, the serious network blockade and censorship in Mainland China (namely the GFW founded in 1998) has given rise to numerous excellent proxy software from China, including but not limited to: Freegate, UltraSurf, SoftEther VPN, GoAgent, Shadowsocks, cow, Lantern, and more. Among them, Shadowsocks (AKA: 影梭) is a free, open-source, cross-platform, encrypted, and secure small proxy project from China. It uses the SOCKS5 proxy protocol (similar to SSH tunnel), and runs very, very fast. In China and many other countries, it's widely used to break through the GFW-like Internet blockade and censorship and access the disturbed, blocked, or shielded web sites and web services around the world, such as Google, YouTube, FaceBook/Twitter, and more.

It is well known that Internet is full of tracking software, advertising, and guys who are monitoring and collecting other people's data for various purposes. In other words, as long as it's on the Internet, you can be exposed to risk at any time. In addition, some websites may block or restrict your access depending on the IP address of your location (you must have encountered such situation: a website just shows you with 403 error). In these cases, using a VPN is the best solution at the moment.

The capacity of hard disk is bigger and bigger, but we can always use up all the disk space very soon. The stored files are more and more and increasingly big are the major factors, however the duplicate files (especially various media files) are another important cause leading to the waste of our hard drive space. This case, we'd better use some duplicate files scanning and cleaning tools to free up disk space with ease.
