I work locally with a WordPress site. When I logged in, it looked like the password was highlighted. It went very fast. Half a second maybe. I found it strange that it looked like it was marked, as in the image below.
The reason I am a bit vigilant is that I have a another site with a special login URL that only the owner of the site and I know about, but sometimes there are unknown login attempts there. Could my PC be hijacked? A trojan? How can I find out?
