360 Secure Browser

360 Secure Browser (360 Security Browser) or 360 Safe Browser[8] (Chinese: 360安全浏览器) is a web browser developed by the Qihoo company of Beijing, China.[9][10] It was first released in September 2008.[9]
The browser by default renders the webpage using the WebKit-based engine adapted for Google Chrome, Blink, and when running in compatibility mode, it renders webpages using the Trident engine found in Internet Explorer.[11][12]

In January 2011, Qihoo claimed that it was the second most popular web browser in China (after Internet Explorer),[10] with 172 million monthly active users, 44.1% of Internet users in China.[13] StatCounter claims that the true figure is between 2-7%.[14] As of November 2014 StatCounter reported that the Qihoo browser was the 5th most popular browser in the United States.[15] Its main competitors in China are the Sogou High-Speed Browser (搜狗高速浏览器) by Sogou, CM Browser, QQ Browser by Tencent, Baidu Browser and Maxthon.
As of 2017, the latest versions of 360 Secure Browser do not offer a distinguishable user-agent string. It spoofs itself either as Google Chrome or Internet Explorer, making it difficult for developers to target or identify.[11] This can cause problems with websites and apps that need to know what browser you're using to work best.
== Controversies[edit] ==
In 2012, a whistleblower reported a hidden backdoor in 360 Secure Browser. The Product Director of 360 Secure Browser, Tao Weihua, accused the whistleblower of "smearing 360 on behalf of Baidu", which the whistleblower said was "the worst professional response in history". Independent analysis of the claim showed that the browser has an "undeclared mechanism (i.e., via ExtSmartWiz.dll) which connects to the server on a regular basis (e.g., every 5 minutes), and allows it to download files of any type (including executables) from the server."[16]
This and other controversies surrounding Qihoo eventually led to the temporary pulling of their products from the iOS App Store.[17]
High usage numbers may be due to the browser being difficult to uninstall, its parent product 360 Safeguard frequently recommending it and a warning pop-up that appears when a user attempts to install another browser, falsely claiming that the other browser is unsafe and should not be run
