The receipt of junk EMail (ie, Scam/spam) can happen with any EMail account. I have 3 such accounts: one on Comcast (my primary one), gmail, and hotmail. For all 3 of them I receive junk mail just about every day. For my Comcast account, I use Outlook 2016, and it's pretty good at detecting such crap, and diverting it to the Junk EMail folder. For gmail and hotmail, they do a pretty good job also. But, for all 3, there is still the occasional one that "slips" by, and winds up in my In Box.
There is no issue in just deleting it/emptying it from the Trash. I often wonder on gmail and hotmail if such deleted "stuff" gets permanently removed. For Outlook 2016, there is away of permanently removing deleted EMails, and I use it every time.
For one's primary EMail account (like the one I have with Comcast), one can purchase the excellent software SpamSieve (
