Ads by CorAdviser

What is CorAdviser?

CorAdviser is a rogue browser plug-in claiming to provide useful features such as coupons, comparison shopping, and the display of special deals/discounts available on shopping websites, all of which supposedly help to save time and money. While some users may find this functionality legitimate and useful, be aware that CorAdviser is classed as adware.

This negative association is made due to a deceptive software marketing method called 'bundling' (stealth installation of additional programs together with the chosen software) employed by the developers to distribute CorAdviser.

Following stealth installation on Internet Explorer, Google Chrome, and Mozilla Firefox, CorAdviser generates various intrusive online advertisements that are likely to redirect users to bogus websites. Clicking these generated ads exposes your computer to risk of infection.

As with regular adware, CorAdviser records various software and hardware information regarding Internet browsing. Types of recorded information include IP addresses, websites visited, search queries, etc.

This collected data may be personally identifiable, and therefore, the presence of this potentially unwanted program (PUP) on your system can result in serious privacy issues or even identity theft. CorAdviser has similar behavior to many other adware-type applications such as View That Deal, OpenXBrowser, Br0wsrAp, and Coupoon.

These apps claims to enable identical useful features, however, none (including CorAdviser) provide any real value for the user - they are developed simply to generate revenue by the display of intrusive online advertisements and sharing collected data with third parties. You are strongly advised to eliminate CorAdviser from your system immediately.

Most adware is distributed using small programs called 'download managers' on freeware download websites such as softonic.com, soft32.com, download.com, etc.

Although download managers supposedly ease the download process, they are employed to monetize these websites' free services and traffic by offering installation of third-party apps together with the chosen software. These promoted applications are described as legitimate, however, they are most likely to be adware or malware.

To avoid such infections, closely inspect each step of the free software download process to ensure that no additional programs are included.

Furthermore, downloaded software should be installed using the 'Advanced' or 'Custom' installation options, since third party applications are often hidden within these options. The Advanced or Custom options will enable you to cancel them. If you have installed CorAdviser, the following removal guide will help you to eliminate this adware from your system.
