What is GreatSaver?
GreatSaver is a browser plugin created by AS Internet Ltd. This extension promises to save time and money when shopping online by displaying various deals.
While such added functionality may seem legitimate, be aware that the GreatSaver plugin is categorized as adware or a potentially unwanted application since it installs on browsers (Internet Explorer, Google Chrome, and Mozilla Firefox) without users' consent when downloading free software. Developers of this add-on use a deceptive software marketing method called 'bundling'.
Today, most free software download websites use deceptive download clients - small programs offering installation of additional browser extensions together with the chosen free software. Therefore, reckless freeware downloading can result in adware infections.
After successful infiltration, the GreatSaver plugin generates various intrusive ads and track users' Internet browsing activity. The presence of this add-on can lead to malware threats and identity theft, and thus, you are strongly advised to eliminate GreatSaver from your Internet browser/s.
GreatSaver is similar to other adware, which installs on browsers together with free software downloaded from the Internet and causes intrusive ads. Examples include Shopper Pro, Sense, and SaveSense. To avoid installation of such potentially unwanted applications, users should express caution when downloading free software.
If the download is managed by a download client, opt-out of installation of advertised browser extensions by clicking the 'decline' button. When installing downloaded freeware, choose the 'Custom' or 'Advanced' installation options, rather than 'Typical' or 'Quick' - this will reveal installation of bundled browser plug-ins.
Computer users who observe GreatSaver ads when surfing the Internet should use this removal guide to eliminate adware from their Internet browser/s.
