Hi!
Here to help!
"Namecheap" is an ICANN-accredited domain name registrar; that means it hosts a variety of websites, including, but not limited to search-sites, ads-sites, info-news-sites, hobby, music, etc.
Malwarebytes will not flag it, because it is not Malware/Adware.
Although out of scope (Google Chromium, not Apple), I will get you going:
- on your Mac, open Chrome;
- At the top right, click MORE : settings;
- Under "Appearance" turn on Show Home Button;
- Below "Show Home Button," choose to use the New Tab Page or a custom page.
If this fails, you could consider resetting the browser altogether:
(Data loss may occur!!)
- On your computer, open Chrome;
- At the top right, click MORE > settings;
- Click reset settings restore settings to their original defaults > reset settings;
Please keep in mind, that in the future, these questions should be adressed here:

Hope this helps!
Kind regards
