Critical-security-alert.info

Critical-security-alert.info is a pop-up that is often the result of installing freeware applications to your computer. Typically, adware applications are bundled with other free apps and for this reason computer security experts advise to be attentive during the installation process and carefully read the EULA (End User License Agreement). In case you have accidentally installed an adware application on your PC, do not be surprised by the presence of Critical-security-alert.info pop-up. The domain only presents a message saying "Suspicious activity of intrusions detected which is trying to redirect you to an attack site. This may happen due to obsolete virus protections. To fix, please call system support at 1-855-666-5543 immediately. Please ensure you do not restart your computer to prevent data loss." In addition, the message is recorded and set to repeat itself for scaring users into thinking that they need to contact their support hotline. Computer security experts do not recommend to communicate with the 'support' as they would require access to your PC.
