What is PacFunction?
Created by a company called SuperWeb LLC, the PacFunction browser extension claims to improve the quality of users' Internet browsing experience by enabling coupons, comparison shopping, and adding other useful functionality. Although this may seem a legitimate browser add-on, be aware that it is categorized as adware or a potentially unwanted application.
PacFunction employs a deceptive software marketing method called 'bundling' (stealth installation of additional applications together with the chosen software) to install on browsers without users' permission.
After successful infiltration on Internet Explorer, Google Chrome, and Mozilla Firefox, this potentially unwanted application generates various intrusive online advertisements including banner, text-link, search, interstitial, transitional, and full page ads. There is a high probability that clicking these ads will lead to high-risk malware or adware infections.
In addition, PacFunction tracks users' Internet browsing activity by recording diverse software and hardware information, which may be personally identifiable, for example, URLs visited, search queries entered, pages viewed, IP addresses, unique identifier numbers, and other similar details.
This behavior may lead to serious privacy issues or identity theft, and therefore, you are advised to remove PacFunction or any other adware from your Internet browsers. The developers of this rogue browser add-on (SuperWeb LLC) have released over one hundred rogue browser plug-ins identical to PacFunction.
Neither PacFunction, nor any other of the aforementioned applications, add any real value for the user - their purpose is to generate revenue by the display of intrusive online advertisements.
Commonly, computer users inadvertently infect their Internet browsers with adware when downloading free software via 'download managers' on freeware download websites (such as download.com, softonic.com, soft32.com, amongst many others).
Download managers are used to monetize these websites' free services by offering installation of promoted browser add-ons together with the chosen free software. Thus, reckless download and installation of freeware often results in adware or malware infections.
This situation can be prevented by closely inspecting each step of the free software download process and clicking the 'Decline' button when installation of any additional applications is offered.
Internet users who have installed downloaded freeware should select the 'Custom' or 'Advanced' installation settings - this will reveal any bundled applications listed for installation and allow users to decline them.
If you have already installed PacFunction and observe "Ads by PacFunction", "PacFunction Deals", and "Powered by PacFunction" advertisements when surfing the Internet, follow this removal guide to eliminate PacFunction adware from your Internet browsers.
