Hi, please try working through [https://malwaretips.com/blogs/remove-ask-toolbar-and-search/ Remove Ask Toolbar and Ask.com Search (Uninstall Guide)] by Malware Tips - the article is a little old so you may have to improvise! '''Note that not all removal programs will detect all malware, so you may need to run several or all of them.''' I suggest you start with AdwCleaner. After removal you may need to reset your home page and search, which you can do by running the add-on [https://addons.mozilla.org/en-US/firefox/addon/searchreset/ SearchReset.] ''If your question is resolved by this or another answer, please take a minute to let us know.
