How to Remove "Tag Archive for"

In my blog, I classify the posts using Categories and Tags and I changed the term “tag” in permalink with “company” but in that tag/company page it still being seen as “Tag Archive for XXXXXX” and not as “Company Archive for XXXXX”.

How to either change the “Tag” term to “Company” or, remove the phrase “Tag Archive for” and keep only “XXXXX”.
