What to do if I was scammed by a Phishing Sharepoint link

I mistakenly clicked on an email from a colleague that was a sharePoint link, turns out it was a phishing link. I (stupidly) entered my office 365 password. Then everyone in my outlook address book got that same email from me. I immediately changed my office 365 password and have done a clean reinstall of Outlook. After a couple of days, everything seems to run fine with no further incident. I'm thinking I should install malware bites and run it to make sure, but I can't find anything on their website about if it is effective against malware that might already be in my machine. Or, should I do a complete clean install of macOS as well? Any thoughts from the experts out there would be appreciated. Thank you.
