Montil is a program that causes your PC to call expensive toll or international phone numbers that may get charged to your telephone bill. Montil connects you to adult websites, most of which are pornographic. These parasites may be installed with your consent, or by accidentally visiting a questionable website. Occasionally, Montil installs on your computer due to the fact that your operating system and security settings are weak.

Prompt removal is indicated, as Montil may install more malware on your PC, which poses a high risk to the health of your computer and personal information.

Malware may collect data about all of your online activities in order to sell this information to third parties. It will also affect your operating system, causing it to become slow and in some instances crash. Montil may be removed manually by locating it in your add/remove programs on your control panel, or you may attempt to locate all related files and delete them. This action is advised against, as improper removal may severely damage your PC. A legitimate antispyware tool such as Spyzooka is recommended to scan your computer for parasites and other security threats. Once detected, they will be completely removed so that your PC is secure again.
