HPRewriter is a browser hijacker and Potentially Unwanted Program (PUP) that changes your home page, new tab page, default search engine, and browser shortcut. The infection will scan your computer for browser shortcuts and modify them with an argument in order to cause your affected browsers to start on a HPRewriter web site every time you open a new browser window.
HPRewriter aggressively replaces your browser settings without consent or knowledge. The potentially unwanted program will replace the browser settings of each internet browser installed on your machine simultaneously. It will replace the home page, new tab page, default search engine, and shortcut in order to cause the affected web browsers to start-up on the website and redirect to the website when a search is performed in the address bar or a new browser tab is manually opened.
When this program is installed it will create a directory folder in this path: C:\Users\User\AppData\Roaming\HPRewriter\RewriterRunner.exe and will run multiple processes that link to the associated webpages it will cause your browser to redirect to. This can use up a lot of resources and cause your internet speeds to become very slow.
