How to Get Rid of System-update.info Pop-up Manually

System-update.info pop-up is caused by an ad-support extension for Internet Explorer, Firefox and Google Chrome. If your computer is installed with System-update.info, your computer system is detected, and after a few minutes, the detected results come out, stating that there are suspicious activities inside your computer and your browser may be directed as an anonymous activity. Corresponding to the fake information, a telephone number is given on the pop-up window. 
Don’t even try to believe on that, the true purpose is not to help you, but to trick you to pay you money for the so-called service or support. Once you find System-update.info or similar symptoms on your computer, you may need to remove System-update.info from your computer as soon as possible. Don’t know how to remove it? Don’t worry!
