Ads by thirteen degrees

What is thirteen degrees?

Thirteen degrees claims to boost the Internet browsing experience, however, this is merely an attempt to trick users into believing that this software is legitimate and useful. Many users do not realize that this browser add-on is adware and a potentially unwanted program (PUP).

The company responsible for the development of thirteen degrees adware (SuperWeb LLC) employs a deceptive software marketing method called 'bundling' to distribute this add-on, and therefore, users often install thirteen degrees inadvertently without their consent.

This application hijacks popular Internet browsers including Internet Explorer, Google Chrome, and Mozilla Firefox. Following infiltration, thirteen degrees displays various intrusive online adverts such as banners, pop-ups, interstitial, transitional, coupon, search, full-page, etc.

Although these ads may seem harmless, they diminish browser performance and Internet speed, and may redirect to dubious websites containing infectious content - thereby exposing your computer to risk of infection.

Furthermore, thirteen degrees collects various Internet browsing-related information including unique identifier numbers, Internet Protocol (IP) addresses (to determine users' geographic locations), search queries entered into search engines, websites visited, pages viewed, entered logins and passwords on certain websites, etc.

This recorded information is likely to be personally identifiable and later shared with third parties. Therefore, this kind of behavior can lead to serious privacy issues or even identity theft. Thirteen degrees belongs to a 'family' of rogue browser plug-ins developed by SuperWeb LLC.

Application Nation, Polished Patterns, Information Vent, Square Corner, and hundreds of other browser add-ons also claim to provide valuable features.

These applications are in fact identical and none provide any real value to the user. The purpose of the thirteen degrees app is to generate revenue by delivering intrusive ads (pay-per-click) and sharing collected details with third parties. You are strongly advised to remove adware-type applications such as thirteen degrees from your system immediately.

Typical freeware download websites such as downloads.com and soft32.com monetize their traffic via small 'download programs' (also called 'download managers', 'download tools', 'installers', 'download clients', etc.) These programs supposedly ease the download process, however, their purpose is to offer installation of additional applications with the chosen software.

Typically, these promoted apps are presented as 'genuine and virus-free', and yet, most are categorized as adware or malware. Thus download programs promote installation of rogue apps such as thirteen degrees. Any offers to install additional applications should be declined.

If you have installed thirteen degrees, the following removal instructions will help you to eliminate this threat from your system.

How did thirteen degrees install on my computer?

As thirteen degrees is often attached to regular (mostly free) software, most users inadvertently install this application.

The problem is that download manager and installer set-ups either hide (within the 'Custom or 'Advanced' options) - or do not properly disclose - installation of third party applications. By skipping installation steps, users expose their computers to risk of infection.

How to avoid installation of potentially unwanted applications?

This type of computer infection can be avoided by closely analysing the freeware download process. When downloading/installing freeware, uncheck any unrecognized or suspicious third party applications. Furthermore, free software downloaded from the Internet should be installed using the 'Custom' or 'Advanced' options - this will reveal any PUPs listed for installation and allow you to decline them.
