How to Remove Logger.js (Chrome/Firefox)

I wrote this article to help you remove Logger.js. This Logger.js removal guide is working for Chrome, Firefox and Internet Explorer.

Logger.js is a malicious Javascript file. It is associated to the Haso.pubmatic.com website. The script functions as a browser hijacker. Haso.pubmatic.com enables it to perform its malicious tasks. In most cases, hijackers are not identified. Only the domain they make use of is known. This case is unique, as the website and the malicious program which exploits it have been linked. This makes the issue more obvious. Haso.pubmatic.com does not have actual content. Its only purpose is to serve the hijacker.

What is dangerous about Logger.js?

The malicious file takes control of the web browser. It can penetrate Google Chrome, Mozilla Firefox and Microsoft Edge. The hijacker accesses the DNS settings and makes changes to them. The purpose is to prevent the browser from hindering its tasks. The main function of Logger.js is to make proceeds for its owners. The changes the hijacker makes to your internal settings will bring down your security.

Logger.js can reset your homepage and default search engine. Hijackers prevent users from reverting back to their custom settings. You should not use an unconfirmed platform to carry out your sessions. Rogue search engines return unreliable results. They insert supported pages amid the regular results to your queries. The sponsored pages may not match the words and phrases you have entered. While this is an inconvenience, it is not that much of a problem. The more severe issue is that the linked websites could be dangerous. They may contain malware.

The same threat is evident with the advertisements Logger.js generates. The hijacker depends on your activity. The more sponsored links users follow, the higher the proceeds for the clandestine program’s owners would be. Logger.js displays windows, containing offers for a variety of shopping goods. The ads are created in miscellaneous formats, including pop-ups, pop-unders, in-text links, coupon boxes, banners, freebies, rebates, contextual, interstitial, floating, transitional, inline and full-page ads. They list exclusive deals in an attempt to attract people. You should not allow the marketing tricks to cloud your better judgment. The ads are risky. It is highly advised to stay away from them.

Another threat you need to be aware of is the potential of your personal details leaking. Logger.js can record data from your browser. This includes history, tracking cookies, keystrokes, IP address, email, geographic location, user names, passwords, physical registration, zip code, telephone number and all other private information you have disclosed through your online accounts. The hijacker provides the gathered input to its owners who can in turn use it as they see fit.

How did Logger.js penetrate my machine?

There are a couple of ways to get infected with the hijacker. The malicious script can be attached to a spam email. Opening Logger.js is enough to launch the download and install of the insidious program. Javascript files can start a process when accessed. To throw you off track, the sender of the fake email will append a false extension to the attachment. The script can be listed as a text document, a .pdf file or an image. It can be packed inside a zipped folder or a compressed archive. Make sure a message is reliable before following any instructions from it. Look up the sender’s name and contacts.

The other propagation vector Logger.js turns to are drive-by installations. This technique requires the least amount of effort. All it takes is to have the user enter the carrier website. The installation process begins right away. It is recommended to take precautions when browsing through unfamiliar websites. Do your own research on the domains you have reservations about. This can prevent a lot of troubles.
