Hello, Thank you in advance for your assistance. Google first flagged infection notified me to change password. Something like, "...computer compromised, malicious activity detected...". In conjunction with, credit card provider declined to accept several payments form "unauthorized back account", and several unauthorized credit card transactions posted to the account.  Malwarebytes (MB) did not open after google notice, and locked up PC, had to pull PC power plus to restart.  Used MB clean up utility to remove and reinstall MB, after which MB, Awdcleaner and Microsoft Defender scan came back clean.
