Erdnt.loc – an advertising network used to fill user's browser with ads right after thr “Allow” button is clicked
Erdnt.loc is an adware-type program[1] which has been spotted as malicious by AVG and other vendors of security software. This PUP can infiltrate the system unnoticed and start its activity by modifying browsers' settings. After that, Erdnt.loc virus starts producing numerous ads which pop out each time the user turns on the affected browser. In addition, it causes “Push notifications” that can fill the victim's web browser with even more ads right after the “Allow” button is clicked. If you do not get rid of the ad-supported program ASAP, your browser might start struggling to maintain even simple activities due to the big amount of adverts that are intruding your computing work.

You can recognize the suspicious adware on your computer from such symptoms:
- You are dealing with Erdnt.loc redirect issue right after you launch your web browser;
- You are interrupted by numerous ads overfilling your computer screen;
- Your browsers' settings have been modified without your approval.
Nevertheless, there is one thing that you cannot see – adware such as Erdnt.loc pop-up has an ability to collect data that is related to the users' browsing habits. Such data includes commonly visited sites, pictures and videos viewed, bookmarks, IPs, and other particular information. Such collected details are used for ad creation. Developers gain more benefit from advertisements that are generated by “taking a look at the user's needs”.
However, you should perform the Erdnt.loc removal as soon as you spot the first signs showing that your computer is infected by the adware-type program. This PUP might redirect you to dubious-looking sites which might promote damaging content. Once clicked, you might launch the installation of a serious malware.
Even though Erdnt.loc is only potentially unwanted, the program does not bring any true value. Besides, various antivirus tools[2] such as Avast or AVG detect it as a virus. However, you should also take into account that such a report can be a false positive as antivirus programs sometimes include numerous entries in their database and start detecting various legitimate files as harmful ones. You might get lost and decide to uninstall a file which truly is necessary for your computer system. We just want to warn you, to be more cautious, and if you see that your antivirus program is acting strangely – perform the recommended updates.
That is why you should double check the system to decide whether you need to remove Erdnt.loc virus. To make sure that there are no harmful components left in your PC, we suggest running a full system scan with updated anti-spyware. You can find manual elimination instructions below the article if you are likely to get rid of the cyber threat on your own. However, you should try installing FortectIntego to make sure that your computer is safe.
Adware prevention techniques
According to NoVirus.uk experts[3], adware-type applications spread very widely throughout the Internet. They can come from various software you have recently downloaded, from a suspicious page you entered, and many other sources, especially third-party ones. If you want to prevent adware infections, you need to know some techniques:
- Install antivirus protection. This type of computer security tool is necessary for every user. It will secure the system from various infections and threats that might occur in your way. Make sure that your antivirus tool is always updated and perform a regular system scan with it once in a while;
- Use only original installers. However, you can track all your downloads by picking the Custom or Advanced option over the Quick or Recommended. Once you are there, opt-out all incoming downloads that you did not request for or look suspicious;
- Stay away from questionable websites. There are many pages that are promoted by secondary sources and come improperly disclosed. Such sites might easily spread malicious content which can be activated only with one click. If you enter a dubious page – be quick to eliminate it and run a system scan with your antivirus program to make sure that no infections managed to break through.
