best way to protect my MacBook
I use a MacBook (ver 12.5.1) for work and am forced to use programs like Microsoft 365 and Citrix Sharefile, an online data storage system. Our office keeps getting hit with malicious messages and have been hacked a few times. I am constantly getting pops up asking me to click this or download that which I will not do. I was using Chrome and Gmail until I found out recently that someone had somehow taken control of my Netflix account as I found a message advising that my netflix was cancelled and when I spoke with Netflix, they said someone had taken control and changed the account into their name using my credit card.
Long story short, I've stopped design Chrome and have gone back to Safari, and am now using the Mail app for the gmail account. I assume this is the safest thing to do.
When I speak with Applecare they advise me that Apple recommends I use malwarebytes on my computer. I tried to explain to the lady that there is no way a one minute scan of my computer which is about what it takes to scan with that program can actual check the 1.8 gigs of data on this computer.
Can anyone advise the best way to check my computer for what I have on the drive, and then the best way to protect it moving forward? I am assuming that is some type of software however, I'm not going to download anything without someone in this community that knows what they're talking about providing some feedback.
I would be very grateful for some feedback. Thank you for your time.
MacBook Pro 15″, macOS 11.3
