Analysts from[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.

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.

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.
