WebBrowser Ads

Also Known As: WebBrowser adware
Type: Adware
Damage level: Medium

What is WebBrowser?

The WebBrowser rogue application employs a deceptive software marketing method called 'bundling' (stealth installation of additional programs together with the chosen free software) to install on computers without users' permission.

Following successful infiltration, WebBrowser generates various intrusive online advertisements including (but not limited to) pop-up and banner ads. It is highly probable that clicking advertisements generated by this potentially unwanted program will lead to high-risk adware or malware infections.

In addition, users' Internet browsing activity is continually monitored, since WebBrowser records various software and hardware information such as IP addresses, website URLs visited, pages visited, search queries, and other details that may be personally identifiable. This information tracking may result in serious privacy issues or even identity theft.

Note that WebBrowser installs together with FastPlayerPRO, which is also a rogue application. There are many applications similar to WebBrowser and FastPlayerPro.

Examples include Protectium, SlimPrice, and Price-Hero among many others. None of these applications provide any significant value for the user - their purpose is to generate revenue by the display of intrusive online ads and sharing collected data with third parties. For these reasons, you are strongly advised to eliminate WebBrowser from your system.

Research shows that most adware is distributed via small programs called 'download managers' on freeware download websites such as download.com, soft32.com, softonic.com, etc. Download managers are used to monetize these websites' free services and traffic by offering installation of additional programs together with the chosen free software.

Thus, reckless download and installation of freeware often results in adware or malware infections, including WebBrowser. This situation can be avoided by closely inspecting each step of the free software download procedure and clicking 'Decline' if installation of any additional programs is offered.

Furthermore, all software downloaded from the Internet should be installed using the 'Advanced' or 'Custom' installation options, rather than 'Quick' or 'Regular' - this will reveal any bundled applications listed for installation and allow you to decline them.

If you have installed WebBrowser, and you observe intrusive online ads while surfing the Internet, follow the removal instructions provided to uninstall this application from your system.
