Also Known As: SquirrelWeb Adware
Type: Adware
Damage level: Medium

What is SquirrelWeb?

Created by SuperWeb LLC, SquirrelWeb is a potentially unwanted program (PUP) claiming to improve users' Internet browsing experience by enabling comparison shopping, coupons, and other functions. While this browser plug-in may seem legitimate and useful, be aware that SquirrelWeb is categorized as adware.

The developers of this PUP employ a deceptive software marketing method called 'bundling' to install SquirrelWeb on Internet browsers without users' permission.

Following successful infiltration on Internet Explorer, Google Chrome, and Mozilla Firefox, SquirrelWeb generates numerous intrusive online advertisements such as banner, search, in-text, transitional, interstitial, and full-page ads. There is a high probability that clicking these advertisements will lead to high-risk adware or malware infections.

Furthermore, this potentially unwanted program continually monitors users' Internet browsing activity by collecting various software and hardware information including IP addresses (to determine users' geo-locations), unique identifier numbers, search queries entered into search engines (Google, Yahoo, Bing, etc.), website URLs visited, pages viewed, and other similar details that are likely to be personally identifiable.

SuperWeb LLC has released over two hundred rogue browser add-ons identical to SquirrelWeb. Rad Rater, KingThink, PlumoWeb, and SunriseBrowse are just a few examples among many others. Neither SquirrelWeb, nor any of these other rogue browser extensions provide any real value for the user.

This company intentionally releases identical browser plug-ins under different names to avoid detection by legitimate anti-spyware and anti-virus programs.

The purpose of these plug-ins is to generate revenue by the display of intrusive online advertisements. In addition, the behavior of these PUPs may result in serious privacy issues or identity theft, and therefore, you are strongly advised to uninstall SquirrelWeb from your Internet browsers.

Close examination of SquirrelWeb reveals that it is mostly distributed via small programs called 'download clients' on freeware download websites such as download.com, softonic.com soft32.com, and many others.

Be aware that download clients are used to monetize these websites' free services and traffic by offering installation of promoted (according to the developers, '100% legitimate and virus-free') browser add-ons together with the chosen free software. Thus, reckless download and installation of freeware often results in adware or malware infections.

To avoid installation of SquirrelWeb, or other similar adware, pay close attention during the download of free software and never accept installation of any additional programs offered. Furthermore, if you are installing downloaded software, select the 'Custom' or 'Advanced' installation options - this will reveal any hidden applications listed for installation and allow you to opt-out.

If you have already installed SquirrelWeb, and observe 'Ads by SquirrelWeb', 'SquirrelWeb Deals', and 'Powered by SquirrelWeb' advertisements when surfing the Internet, read the removal instructions provided and eliminate this adware from your Internet browsers'.
