Trying to get galaxy s8 phone out of android lock

[Android Central Question]

Had spam ads popping up while using my s8, so I powered down the phone and turned it back on. But once I did that it worked fine for a few minutes and screen became unlockable. The so I factory reset the phone and it is on android lock. I know my gmail but forgot my password and now stuck.
