you said you weren't using a fake blockchain,info right? did you install any new or suspicious addon on your browser
I use Chromium --incognito with only the basic and well known addons activated. In addition I use Firejail to further insulate my linux OS. In addition I pay for a well known vpn service.
This browser is used ONLY for logins to email, exchanges, banking, and storage. Any other activity is done with other browsers.
2FA on everything including email. Sms if its offered. Gmail and Zoho have excellent sms verification.
Virus scan is done daily with ClamAV.
Bleachbit is ran regularly to further purge temp files, cookies, and such.
I've not had an issue today.
Thanks for the comments thus far.
