What is Prime Updater

Prime Updater or PrimUp! or PrimeUpd is misleading application, that pretends to be software updater, but in fact delivers ads and pop-ups in Google Chrome, Mozilla Firefox and Internet Explorer.

This can surely ruin your privacy and computer security. Use this tutorial to remove Prime Updater from your version of Windows and get rid of ads and pop-ups in browsers.
