Understand the risks that emerge from using Baidu.com

Hao123 image

Baidu.com is a legitimate Chinese search engine that has evolved into one of the biggest search providers. Since malevolent people seek quick and easy profits, they developed highly unreliable browser extensions, plug-ins and other programs to disguise under the name of a verified search engine. Analysts from Wubingdu.cn[1] warn that not all services of this website are safe to use.

There have been various discussions on the web about Hao123 by Baidu, which is a browser plug-in provided by this search engine. IT experts even classify some its versions as potentially unwanted or ad-supported programs alongside the browser hijacker category. It means that after being installed on the system, the virus takes control over each of web browsers and alters the default search provider, the start page, and a new tab window by force. This way, third parties that sponsor this malicious plug-in version get the chance to present their unreliable links to inexperienced computer users.

That's why you may start noticing redirects to the suspicious websites that are certainly irrelevant to the search terms that you have entered. Due to Hao123 redirect tendency, you might land on an infected page as well. According to our research, it currently transfers people to Hao123.com, cn.hao123.com and similar sites that are used for affiliate marketing purposes.

The reason why Hao123 by Baidu redirects to sponsored domains and bombards you with commercial content is that it aims to generate pay-per-click revenue for its developers. The potentially unwanted program (PUP) identifies particular users' preferences and creates more relevant and personalized advertisements, apps, and websites. As a result, people get confused and unable to identify the origins of the intrusive ads. Developers take advantage of it since people willingly click on the questionable advertisements and increase their profits.

Questions about Baidu.com

The screenshot of Hao123 hijacker and Skype virusThough Biadu.com is a safe domain, it is affiliated with Hao123 browser hijacker.

Unfortunately, the US Senate approved the legislation for online advertisers to trade and sell your browsing data among themselves and partners[2]. Needless to say, that the line between users' privacy and its violation becomes more than transparent. Likewise, similar laws only encourage crooks and malevolent people of various ilk to engage in the activities of creating browser hijackers.

Though the privacy policy of baidu.com commits to protecting your privacy, there is no applicable Privacy Policy provided on Hao 123 website. In relation, the ad-supported program may collect personally identifiable information as well. The suspicious and disturbing content provided on the main page only enforces such assumptions. That's why you are strongly advised to remove Hao123 by Baidu with the help of ReimageIntego. Of course, you can also use an alternative anti-spyware program. 

IT technicians spotted Skype virus spreading links to the browser hijacker

Recently, victims of Skype virus reported about the message that contains a suspicious link to Baidu website[3]. Crooks managed to hack the system and send the malicious text to the infected computers. What is more, the link contained the skype name of the recipient contact. Such feature might have tempted more credible users to click on the link.

According to the behavior of this malware, it operates as a computer worm — when a gullible person clicks on the link, all of his or her contacts receive the fraudulent link as well.

The specifications of this malware also resemble Facebook video virus which sends a video file with the personal profile picture to lure users into clicking on the malicious link without having the slightest suspicion of the virtual infection. These deceptive distribution methods have helped to successfully infiltrate various types of viruses worldwide. 

Therefore, if you notice the presence of this Skype virus redirecting to Baidu link, do not click on it, ignore it. It might be beneficial to change your password and check your system whether it does not contain any questionable applications as well. 

Hao123 hijacker's distribution techniques

You can protect your system from potentially unwanted programs (PUPs) and other malicious applications by understanding the methods that hackers employ to distribute them. 

Since users pay little attention to the installation wizards, they often end up installing questionable optional software along with the primary one. This is an extremely popular distribution technique called bundling when the contrivers spread PUPs in one package with freeware.

To avoid falling into the trap of the browser hijacker, make sure you choose Custom/Advanced settings next time you download a new program. They disclose optional attachments and applications. Furthermore, watch for irrelevant add-ons and remove the checkmarks from them.

Note that well-known apps such as Skype and Java may also contain shady attachments, so should pay extreme attention while installing popular programs as well. It will reduce the risk of experiencing the annoying after-effects of Hao123 virus.

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

 

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
