Quiente (formerly lagSoft) is a Facebook application that lets you know who visited your profile, reviewed your photos or deleted you from your contact list. Also promoted as Qsocial.net. The Facebook team, however, flatly denies that this is possible. It even asks its users to denounce this kind of applications, since its developers only look to install some malware or malicious software in the PC to steal personal data.
Therefore, we recommend that you do not allow access to your personal information to applications or websites of dubious reputation. They might only be interested in stealing your information in order to create a database and send targeted advertising. If you have the application installed, it is best to uninstall it.
How To Uninstall Quiente from a Facebook Account
In your Facebook profile, click on the small inverted arrow and select Settings. Go to the Applications category, hover over the Quiente app and click on the X.
