Thinking you're safe would be the biggest mistake. It's a lot safer, but even if it's a lot smaller, there's always a risk. So assume you're not safe, and act accordingly.
This has happened to me, but I'm lucky I didn't lose a few Bitcoins. I tried to eliminate add ons in Chrome settings, even it was gone when my Laptop turned off and turned on again it will always come back. Even in the end I needed to reinstall my windows when I found out this. Luckily I did a double check before sending crypto. Right now I'm still using Chrome, and some anti-virus. My mistake at that time was trying to install some video editor from an unofficial link and using crack. So there are many factors and we have to be meticulous and careful in every step related to the Internet. Even until now I am still looking for the best browser to access the internet.
