Every time I open a new web page it is Ask instead of Google Chrome as it previously was, and I want to remove it
Have a read of the following - and see if they resolve it for you... https://discussions.apple.com/threa...
Sadly the good olde Malwarebytes works only for Windows...; otherwise one might suggest it first... However possibly the free trial version of this (alleged equivalent - if not better; their claim not mine) may be worth to check out if the above suggestions don't work?

Worth remembering that: when you install "any utility - regardless of where from etc - ensure you do not opt for an automatic installation Go the custom route and carefully ensure that you uncheck all those useful prechecked/pretagged/pre-accepted offers of "useful stuff"they would like you to accept too. Likely you have installed "something or other" in the recent past; and that included the ASK item - and possibly other items too.
