Browser Shield Adware
Written by Tomas Meskauskas on (updated)
What is Browser Shield?
Created by Intriguing Apps, Browser Shield is a rogue browser plug-in claiming to enhance user-browsing protection by preventing malware and spyware infections. Although this functionality may seem legitimate and useful, be aware that Browser Shield is categorized as a potentially unwanted program (PUP) or adware.
The developers of this PUP employ a deceptive software marketing method called 'bundling' to stealthily install Browser Shield on Internet browsers (Internet Explorer, Mozilla Firefox, and Google Chrome) without users' permission.
After successful infiltration, Browser Shield generates numerous intrusive online advertisements including pop-up, banner, interstitial, targeted video, coupon ads, and download offers of other rogue browser extensions considered to be adware. Clicking these advertisements is likely to cause high-risk adware or malware infections.
In addition, Browser Shield continually monitors users' Internet browsing activity by collecting information such as IP addresses, unique identifier numbers, search terms entered into search engines (Google, Bing, etc.), geo-locations, and other details that may be personally identifiable.
There are many PUPs similar to Browser Shield, for example, Protect Surf, Clean Browse, Browser Hero, and Web Security App. None of these browser plug-ins add any real value, since their purpose is to generate income by the display of intrusive online advertisements.
This behavior may lead to serious privacy issues or identity theft, and therefore, you are strongly advised to eliminate Browser Shield from your Internet browsers.
At time of research, Browser Shield was distributed via fake downloads (Browser updates, Java updates, etc.) as well as other PUPs such as Browser Guardian, Solid Savings, and other savings and coupon related ads.
Browser Shield is also distributed via small download programs called 'download managers' employed by freeware download websites including download.com, softonic.com, and soft32.com Download managers are used to monetize these websites' free services by offering installation of promoted 'legitimate' browser add-ons together with the chosen free software.
Thus, reckless download and installation of freeware risks computer infection with adware or malware. To avoid installation of Browser Shield, or other similar adware, closely inspect each step of the free software download process and click 'Decline' when installation of any additional programs is offered.
If you are installing downloaded software, select the 'Custom' or 'Advanced' installation options - this will reveal any hidden applications bundled for installation and allow you to decline them. If you have already installed Browser Shield, follow this removal guide to eliminate it from your Internet browsers.
