Using updated google chrome for many years.....recently, I have been getting this warning and it started about April 5.....I've cleared the heck out of my cache and cookies but it keeps showing up....anyone have any ideas? See below....
Maybe somebody with same IP (household, company network) has malware and is trying to log in to your account. I would give it a pause (1h to 24h if possible), then change password and try within other browser, extensions disabled.
This is not a Google chrome issue, but unusual activity on your Google account. This does not mean that somebody is trying to break into your account, but that your account is involved in unusual activity, like sending or receiving a large number of emails within a short period of time, or something similar that is not normal. When you regain account access, log into your Google account and check recent activity/history under "manage your google account" and see if something unusual is listed there. Also consult this Google Help Page: Investigate suspicious activity on your account
