Email Attachment

I have a quick question. I clicked on a picture attachment on an email. My question is this IF they put something on that picture to go into my phone. Is there a way that they can access everything on my phone?? Like the app I use for my money?? That’s mostly the one I’m worried about. Like could they empty my bank account overnight?? If I change my password to the app they’re still going to see the new password.

Is there a free app that will scan for malware and other attacks? Does this Avast app do that or which version will do it?? That will search for anything injected into my phone??
