How do I get rid of isearch.fantastigames. I was downloading a free CCLEANER and followed instructions. The next time I booted up, it was there.

Question

http://isearch.fantastigames.com/439 keeps on coming up on my webpage instead of Mozilla/Yahoo. I cannot get rid of it. Is this MALWARE? My PCPITSTOP expired so I searched for a pc cleaner and found CCLEANER and downloaded it. Followed instructions and the next time I started FIREFOX, it was now my new search engine. I hope that I am phrasing this right. Thanks.

Answer 1

You have downloaded CCleaner from page that bundles downloads with various toolbars. So while you are not infected with malware, you got a PUP - potentially unwanted application.
What you should do:
1. Go through your addons list and remove everything you do not recognize
2. Reset your search providers in Firefox AND in other browsers (it is likely to affect all main browsers on your PC, no mater which one you use)
For firefox: [[Remove a toolbar that has taken over your Firefox search or home page|https://support.mozilla.org/en-US/kb/remove-toolbar-has-taken-over-your-firefox-search]]
For other browsers you [http://www.majauskas.com/how-to-manage-browser-search-providers can try this one]
3. Scan with anti-adware programs
