Hi, you can try these free programs to scan for malware, which work with your existing antivirus software, and hopefully the normal Firefox start page with the Restore button will return when it is removed: * [http://www.microsoft.com/security/scanner/default.aspx Microsoft Safety Scanner] * [http://www.malwarebytes.org/products/malwarebytes_free/ MalwareBytes' Anti-Malware] * [http://support.kaspersky.com/viruses/disinfection/5350 Anti-Rootkit Utility - TDSSKiller] * [http://general-changelog-team.fr/en/downloads/viewdownload/20-outils-de-xplode/2-adwcleaner AdwCleaner] (for more info, see this [http://www.bleepingcomputer.com/download/adwcleaner/ alternate AdwCleaner download page]) * [http://www.surfright.nl/en/hitmanpro/ Hitman Pro] * [http://www.eset.com/us/online-scanner/ ESET Online Scanner] '''Note that not all removal programs will detect all malware, so you may need to run several or all of them.''' You can also check your Firefox Desktop shortcut for corruption: Right click on it > Properties, and in Target, make sure there is no sign of the malware. If there is, delete that part of it. Or if it's easier, you can just delete and recreate a new shortcut. Another thing you can do, is to search for the malware in your PC's search box. 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.] Also see: [[Restore previous session - Configure when Firefox shows your most recent tabs and windows]] ''If your question is resolved by this or another answer, please take a minute to let us know.
