Remove Mbrowser.us virus (Free Instructions) - Easy Removal Guide

removal by Gabriel E. Hall - - | Type: Browser hijacker

Instead of letting searching for the information properly Mbrowser.us redirects to sponsored sites

The main page of Mbrowser.us search engine

Mbrowser.us (also known as Moppo Browser) is a browser hijacker that is advertised as an advanced search engine. This tool belongs to AirFind that are known for creating numerous similar programs. Besides, it is closely related to another browser hijacker – Trivago. It goes without saying that you should not trust it.

Mbrowser.us virus might affect computers during installation of various free programs. After the hijack, it might set its domain as default search engine and homepage. To prevent users from switching back to the previous settings, it makes a few modifications in Registry and Windows shortcuts.

Judging from the appearance, Mbrowser.us looks legitimate. It also has a bonus feature – quick access to popular social networks, shopping and other sites. However, the most important feature of the search engine is a delivery of accurate results; and this tool fails here.

Instead of redirecting to Google or Yahoo search results page, the hijacker uses its database. In this way, authors of the search engine can modify the results and trigger redirects to partner’s websites. Indeed, this activity is unfair, but these Mbrowser.us redirect issues might pose a danger as well.[1]

In the search results page, users receive ads and organic links. However, clicking a web result may not lead you to the needed Internet site. You might be redirected to a third-party site that has nothing in common with your search query. Of course, it’s frustrating, but developers profit from the forced visits to sponsored websites.

Such redirects might be unsafe too. Cybercriminals often take advantage of these programs to reach potential victims. Therefore, the hijacker might reroute users to tech support scam, phishing or infected website. Thus, having this PUP installed, might lead to bigger problems than browsing-related issues. Undoubtedly Mbrowser.us removal is a must.

The best choice to remove Mbrowser.us from the PC is to employ anti-malware.[2] Automatic elimination ensures that all hijacker-related entries are eliminated. If you are not sure which security program to choose, take our advice and give Reimage Reimage Cleaner Intego a try.

However, you should not blame the software. You may have avoided this situation if you have followed these rules:

  • Read the information provided in each installation step.
  • Do not agree to install additional programs.
  • Do not leave marked confirmation to change your default search engine.

Security experts from the Netherlands[3] also stress out the necessity to choose reliable software download sources. Reading End-user license agreement and Privacy policy is also recommended.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
