Hi Elaine, Your system details show that the nuisance is installed in :<BR>Options => Add-ons => Extensions, so , removing it there is the first thing you should do. And look for any other unfamilar or suspicious looking extensions as well. Do the same in Windows Control Panel. However : most malware will be 'hiding' somewhere , so let's run malware scans (better safe than sorry) : 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'''. They all work differently - what one program doesn't pick up, the other might. Also see : https://www.2-spyware.com/remove-search-encrypt.html
