Is it possible to insert java script into someone's Gmail / Google account to hack and track all email and browsing history? I ask because our gmail accounts have been hacked and changing the password does not appear to make any difference. A few years back, my gmail was hacked and every person I emailed had a symbol next to their name that looked like a Q with a more squiggly tail. Nothing I could do could prevent this from automatically appearing. I would be able to delete it before I sent an email out. Then it just stopped. Presently, my email has by far too much going on when you look at "inspect element" so I'm wondering if the same thing is happening again.
Any ideas, hints, suggestions.
