What is Key Tag

Also known as Tag Search, Key Tag is a browser hijacker designed to change your default search provider. Put differently, instead of having search queries redirected through regular engines like Google or Yahoo.com, users are forced to face other dubious domains. Key Tag was spotted to navigate users’ queries through two suspicious domains – keysearchs.com and search-land.com. Such modifications assigned by hijackers are most likely used to generate illegal traffic and earn money from it. Also, Key Tag may use its capabilities to forward users to many potentially unwanted or dangerous pages. Resources of such may be designed to promote fake push notifications, dubious ads, or malicious software. Although Key Tag is not a virus itself, its capabilities are more than enough to make your PC face serious risks. Thus, we strongly advise you to immediately wipe its operation and restore a safe browsing experience. Do it using our full-fledged guide below.

How Key Tag infected your computer

Key Tag is likely to be installed in your browser as an extension or add-on. Although such extensions are very unwanted, they are still likely to be officially available in legitimate extension web stores. The download page for this specific hijacker has been promoted through the dubious “Flash SD App” download page. After clicking on the download button, the page advertising fake Flash SD Apps dropped users over to the Key Tag web store page. Users may be tricked into downloading such software because they are said it is important or urgent. Phishing pages use mental levers to pull inexperienced users into following their requests. Never do this and beware of such distribution methods in the future. It is also worth mentioning that unwanted extensions and apps can be delivered through pirated or cracked software downloaded from torrent and P2P pages. Be careful and try to avoid such channels as much as possible. Along with the removal instructions below, we also attached some recommendations for protecting yourself against such threats in the future.
