What is startupfraction.com virus?
Startupfraction.com virus is a term used to describe a browser hijacker infection caused by rogue browser extensions and add ons including the Bachbut extension for Google Chrome. The native extensions add ons modify existing internet browser settings and cause affected internet browsers to redirect to http://startupfraction.com/ when a search is performed in the address bar.

This means that there is a good chance your computer is infected with other threats that should be eradicated immediately.
