I used to use DDG but started to dislike it after a while - it is still available on the search engine list but not used.
I do have Ixquick
which is similar, and Lycos, only because my daughter knows the sister of the bloke who started it.
Used to use Dogpile
years ago, similar to DDG.
When I install a new OS version it always defaults to Yahoo! Dreadful.
First job is to bin it and install Google.
I have minimal spam, usually one a month on Gmail and half a dozen on my BT Yahoo account. Similar on the three other email accounts.
