Out of curiosity about what Google knows about me, I was poking around in my Dashboard today, and checked in on my web history. Much to my surprise, there's a lot of weird activity in there that's not from me. To be on the safe side, I cleared my cookies and my cache, and changed my Google password to something stupidly difficult.
And when I went back to look at the weird activity again, there was more. In those seconds.
So...WTF is going on? Is my account compromised? Do I have a keylogger or other spyware on this (2nd hand from my dad) computer that I'm using while my laptop is out of commission (all Macs)? Or am I experiencing some kind of harmless Google glitch?
Any insight?
