What is Bachbut?
Bachbut is a browser extension that is known to cause various issues for those who have found it installed. The description for the Bachbut extension says “Whiohoo! Welcome back to Bachbut.” Once the Bachbut extension is installed it will modify search settings and replace the existing search engine with http://startupfraction.com/yaakovhi/?keyword=.
Once this happens, all searches carried out in the address bar of the affected web browser will redirect to startupfraction.com and then to search.yahoo.com.
The Bachbut extension essentially generates revenue from the advertisements displayed on websites it redirects you to, sponsored search content, information it reads and sells about you, and from affiliated downloads.
The Bachbut extension for Google Chrome has permissions that allow it to read and change all your data on the websites you visit. This allows the extension to gather information about your browsing habits and internet history. The extension can also change your search settings which will result in redirected internet searches.
One of the biggest concerns with the extension is that is is typically advertised by questionable advertising networks on websites that also promote malware, adware, spyware, and other malicious threats. This means that if you found the Bachbut extension attached to your internet browser without your consent or have been attacked by Bachbut advertisements it is likely that your computer is infected with other malicious programs that should be removed immediately.
