Hi, if you need further help, please try working through Remove Ask Toolbar and Ask.com Search by Malware Tips - sorry the article is a little old, so you may have to improvise slightly!

Note that not all removal programs will detect all malware, so you may need to run several or all of them.

After removal you may need to reset your home page and search, which you can do by running the add-on SearchReset.

If your question is resolved by this or another answer, please take a minute to let us know. Thank you.
