Greetings I hope to get a bit of advice. My Google account keeps getting compromise where I received an email from Google saying that someone has my password. This the second time in two weeks where an unknown device is tried to log into my account. Google stopped these login attempts with the correct password most likely due to geolocation. I'm in possession of all my devices. My Google account password 100 characters long and so is my LastPass master password. Both of which I changed within minutes of the the first email from Google. It seems someone through my background looking at previous places I've lived to try to login with them the correct geolocation area.
I'm perplexed on how someone could be in possession or guessed my password. I use Malwarebytes Anti-Malware premium which hasn't found anything relevant. My best guess is there's Malware on my computer. Although my pc asymptomatic outside of the instances of my Google account being compromised. Thoughts of how I should proceed besides two factor authentication as I'm concerned with the source of the leak?
