Firefox had malware in it that defeats my ability to get rid of it. So I got rid of firefox and decided to download a whole new updated firefox. And it had the same maleware in it! That cryptosearch engine or whatever it is. And I cannot get rid of it no matter what. Even new Firefox the cryptosearch engine is in it already! How can this be fixed?

Did you get the browser from Mozilla.org?


You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.

note that some anti-virus software detects malware in the small stub installer that requires access to internet as a false positive. Using the full installer as posted above should work.

the full installer seemed to have "malware in your browser" as one of the languages in which firefox could be installed! Why would that be? Also, I could not seem to find "English" as an option.

Also, I did not find the full installer as posted above. Still afraid to use Firefox at all.

I did the refresher thing as you suggested. Great advice! Problem solved!

The full setup for Windows is on the www.mozilla.org/firefox/all/ page you were linked to. There are three English versions British, South African, and US as you can see at https://www.mozilla.org/firefox/all/#en-GB

No official versions of Firefox for Windows, Mac, or Linux from Mozilla has ever been found to have malware. It would hurt Mozilla and the Firefox browser far too much for what little financial gain from it. It would be a hot topic here, at independent forums.mozillazine.org and tech sites around if this was true.

However back a very longtime ago before Firefox Releases got to version 1.0 that some people think Firefox started at, there were no other official locales besides en-US and a contributed Chinese build of Firebird 0.6 (I think it was) was reportedly found to have some maleware.
