Thanks for that additional info jeannine p
UPDATE:
TAZ said that the program to scan and clear my computer of any malware would not stay permanently on my computer, and it HAS disappeared. Can't find it on my list of programs to uninstall. So - I think all is well. They listed 4 items cleared from my computer which were all related sites, and when I googled them I found that they were mostly used on Windows 8. My computer came loaded with W8 (which I hated), but I now have W10 - it was downloaded in July, I think. Those programs might have come with W8.
