Spyware and malware

Spyware and other malicious software (malware), including variants of the Vundo/Virtumonde trojan, can cause certain sites to never finish loading and Google, Yahoo!, or other search engines may fail. [3] [4] [5] [6] For example, after entering a search in Google, "Waiting for www.google.com..." may remain in the status bar and no results will be returned. Your security software may not detect the malware so you should install and run another application that can scan your system and remove the malware or seek help from a forum specializing in malware removal. Some recommended anti-malware applications and help forums are listed here.

Searches being redirected

If searches are being redirected to an unwanted search engine such as Ask.com, disable or uninstall any extensions and remove any added toolbars that you suspect may be interfering with Web searches. Also reset any preferences in about:config that refer to the removed add-on or unwanted search engine. See this forum topic for additional information.

Note: If typing an incorrect address in the Location Bar redirects you to a results page from an unwanted search engine, this is a different issue. Your ISP (Internet Service Provider) may be intercepting the failed DNS requests, as discussed here.

If the problem persists or if your search results are being redirected to unwanted websites, check for malware. [7]

Search Bar not working and cannot add new search engines

If the Search Bar no longer works and you can't add new search engines, the problem may be a corrupt "search.sqlite" file. [8]. Try the following solution:

  1. Exit Firefox and go to your Firefox profile folder.
  2. Delete (or rename) the file "search.sqlite".
  3. Re-start Firefox to see if it solves your problem.
