What is FirstOffer?
FirstOffer is a dubious browser extension presenting itself as a legitimate app to save time and money while shopping online - "F1rstOffer is your shortcut to online savings. Our company provides an intuitive tool that helps you uncover competitive prices on commercial products, so you can save money on the items you love."
Initially, these false claims may trick some users into believing that FirstOffer is a legitimate and useful browser add-on, however, it is categorized as a potentially unwanted program (PUP) and adware. There are a number of reasons for these negative associations.
Firstly, this PUP infiltrates the Internet Explorer, Google Chrome, and Mozilla Firefox browsers without users' permission. Following successful infiltration, FirstOffer displays intrusive online advertisements and collects various Internet browsing-related information.
This application displays a variety of advertisements including banners, pop-ups, coupons, and price comparison ads. Advertisements are displayed using a virtual layer, which allows placement of any graphical content on visited sites.
The virtual layer overlays the entire website with advertisements hiding underlying content, thereby significantly diminishing the Internet browsing experience. The generated ads can redirect to infectious sites, and therefore, clicking them is risky and may cause further computer infections.
Furthermore, this adware continually monitors Internet browsing activity and may collect information that is personally identifiable.
This gathered data is later shared with third parties, and therefore, having FirstOffer installed on your system can lead to various privacy issues. For these reasons, we strongly recommend that you uninstall FirstOffer from your system immediately.
This browser plug-in is not the only one claiming to save time and money. There are hundreds of other adware-type apps (for example, Awesome Shopper, TidyNetwork, and BitSaver) also offering identical features. Neither FirstOffer, nor any of these other applications, provide the functionality promised.
The purpose of applications such as FirstOffer is to generate revenue for the developers - they simply display advertisements and collect various user/system information.
How did FirstOffer install on my computer?
Adware-type applications (including FirstOffer) are often distributed using a deceptive software marketing method called 'bundling' - stealth installation of third party apps with regular software/apps. Bundling is effective since many users do not pay enough attention when downloading and installing software.
The developers are aware that users often rush these processes and skip most steps, thus, they intentionally conceal rogue applications such as FirstOffer within the 'Custom' or 'Advanced' settings. Unaware of this, many users often rush these processes and inadvertently install rogue apps.
How to avoid installation of potentially unwanted applications?
Do not rush the download or installation processes. Closely follow each step and decline all offers to install additional applications. Furthermore, select the 'Custom' or 'Advanced' options, rather than 'Quick' or 'Typical' - this will reveal any hidden rogue applications listed for installation and enable you to decline them.
