Linkey Project Screenshot 1The Linkey Project is a Potentially Unwanted Program that modifies your browser to promote various websites through additional links. Potential issues related to the Linkey Project may include a hijacked homepage or search engine, as well as general browser performance problems that are detrimental to your Web browser. Although malware experts have looked the Linkey Project over and found the Linkey Project insufficiently unsafe to be considered as a threat, deleting the Linkey Project and similar PUPs may provide you with a better Internet-surfing experience than letting them stay on your computer.

The Linking Project You May Be Rethinking When You Opt In

The Linkey Project claims to offer 'quick and easy' access to popular websites, but, as a browser add-on, the Linkey Project offers few features of any value. Because the Linkey Project still is being developed and may add or subtract features over time, malware researchers can't verify all of the Linkey Project's functions. However, common problems that previous users of the Linkey Project have complained about include:

  • Worsened browser performance. This potentially may be caused by the Linkey Project monitoring your Web-browsing habits for non-confidential data, such as your favorite search terms or websites.
  • Homepage, search or new tab hijacks that redirect you to the Linkey Project's primary application page. Although the Linkey Project's page doesn't provide any intentionally corrupted links, being redirected to this page may prevent you from using an alternative site or choosing your own Web-browsing settings. Recurring issues in this area may cause malware experts to classify the Linkey Project as a browser hijacker, as well as a PUP.
  • The Linkey Project doesn't try to harm your computer intentionally, but the Linkey Project does ignore your default Web-browsing settings and may deny you the chance to regulate your browser's behavior yourself. Perhaps most importantly, the Linkey Project claims to be beneficial to your PC but, like most PUPs, is more of a case of valueless software clutter than anything else.

Unlinking Your Browser from a Project with Little Benefit

The browser changes made by the Linkey Project may not be equivalent to the direct attacks of a banking Trojan or similar threat, but, still, they aren't to your overall advantage. You can make your own decision about how valuable you find the Linkey Project to be, but malware researchers always would call for deleting the Linkey Project and other PUPs for keeping your browser's performance and safety maximized. This is applicable to all browsers affected by the Linkey Project, which, so far, include Chrome, Firefox and, as usual, the often-abused Internet Explorer.

Removing the Linkey Project with anti-malware tools will provide the cleanest uninstallation process and help keep your browser from displaying any additional unwanted behavior. During scans where your security suite fails to recognize the Linkey Project as a PUP, malware experts would recommend installing any available database updates before making a second attempt.
