R3.o.lencr.org

R3.o.lencr.org is a browser-redirecting app that attaches itself to the main browser in the computer and takes control over some of its settings. R3.o.lencr.org aims to bring different ads to the user’s screen and to promote certain sites by page-redirecting the browser to them.

R3.o.lencr.org
The R3.o.lencr.org Malware will make unwanted changes to your browser.

This is not an uncommon type of software and many computer users (both Windows and Mac) are forced to deal with the consequences of having such an app installed in their systems. R3.o.lencr.org, in particular, is a Windows browser hijacker. It typically spreads via spam messages and file bundles so that more users would install it without actually realizing it. For example, this app may be added as an optional element to the installer of some other program and get installed alongside it. Once installed, R3.o.lencr.org takes over the homepage and the main search engine of the browser. It could be Chrome, Firefox, Edge, Opera or another browser that gets targeted by this app – it doesn’t matter. Most representatives of the browser hijacker category don’t have any compatibility limitations. They are optimized to be as widely compatible as possible so that they can reach a big number of users.

Of course, the end goal of all this is to make money from the ads that this unwanted app displays and from the paid page redirects that it triggers in the browser. Even though to some users this may not seem like too serious of a problem, once a hijacker like R3.o.lencr.org gets installed in the browser, it quickly becomes apparent that surfing the Internet in peace is no longer an option. The undesirable app would keep showering different pop-ups, banners, and box messages on your screen and it will frequently redirect the browser to the sites it is tasked with popularizing. This could make it quite difficult and frustrating to reach the information you are looking for while using the infected browser. Getting a new browser, however, is not a very good solution to this problem, because the unwanted app would still be present in your computer and this may potentially lead to some more serious issues in the long run.

The R3.o.lencr.org Malware

The R3.o.lencr.org malware is not programmed to cause damage or to carry out any criminal activities in the computers it is installed. The R3.o.lencr.org malware is, above all, an advertising app, which means that it will mainly focus on generating revenue through its paid ads and site-promoting activities.

However, this is where the real problems may start to occur. Many of the sites that use the promoting services of apps like R3.o.lencr.org are not to be trusted. Some may even be illegal and be used for spreading different kinds of malicious software, including Ransomware file-encrypting viruses, Trojan horses, and Spyware. In other cases, the hijacker may land you on a fake page that contains phishing elements aimed at extracting sensitive information about you (for example, credit or debit card numbers).

Endangering your computer or virtual privacy may not be the goal of the people behind R3.o.lencr.org, but this may still end up being an indirect result of the advertising activities of this app. Therefore, if you want to keep your PC safe and secure and if you want to stay away from Ransomware, Worms, Trojans, or other threats, we advise you to use the removal guide we’ve prepared and posted below and uninstall the hijacker with its help.

    Step3

    Open a Run window by using the Start and R key combination.

    Nextр type appwiz.cpl in the Run window and click OK.

    appwiz

    The command will open a Control Panel window where you will be able to see all apps that are currently installed on your computer. Look for suspicious entries in the list and Uninstall them if you find out that there are potentially unwanted or could be responsible for the browser hijacking problem.

    Next, open the System Configuration window by typing msconfig in the windows search field, followed by Enter.

    msconfig_opt

    In the Startup tabDisable any startup items that seem to have a relation to R3.o.lencr.org or look suspicious, have “Unknown” Manufacturer, etc. The easiest way to disable a Startup item is to simply remove its checkmark from the checkbox.

    Step4

    Press Start and R keyboard keys together and  copy the line below in the Run window that pops up:

    notepad %windir%/system32/Drivers/etc/hosts

    Click OK and this should immediately open a text file called Hosts. Scroll down the text of the Hosts file until you find where it is written Localhost. It should be somewhere at the bottom. Then, check if some strange IPs have been added below Localhost. The image below explains what you should be looking for:

    hosts_opt (1)

    Please, write to us in the comments if you find any suspicious IP addresses in your Hosts file. A member of our team will take a look at them and will tell you if they are dangerous and need to be deleted or not.

    1. Select the currently active Network Adapter, right-click on it, and select Properties.
    2. Find Internet Protocol Version 4 (ICP/IP) and select it, then click on the active Properties button.
    3. Select the Obtain DNS server automatically option in the new window and then click on Advanced.
    4. In the Advanced TCP/IP settings window click on the DNS tab. If any rogue DNS has been added there, remove it and click OK to save the changes.
