V9, also known as V9 Search or V9.com, is a browser hijacker, a kind of potentially unwanted program or "PUP" often distributed through free software downloads. Once installed, V9 changes your primary Web browser's home page to v9.com and its default search engine to search.v9.com, which returns primarily paid ad results.
To remove V9, you could follow the removal instructions on V9's own website, but they're oddly written and somewhat out of date. To make sure V9 is fully removed, you should instead reset your browser, as detailed in the following links.

V9 may be accompanied by hidden programs that reinstall V9 after a browser reset. These programs, which are sometimes called BrowserProtect, eSave Security Control, New Tabs Uninstall or Wsys Control, can be removed by adware-removal tools such as AdwCleaner, CCleaner or Malwarebytes Anti-Malware.
