Let me explain. I left my computer on today, with Google Talk running, and then I went to school. At school I was able to log on Google Talk for my first period class. Then for my second class, I tried logging on, but it wouldn't let me at all. So I thought maybe someone changed it in the first class, but only two of my friends were sitting next to me, and the only time i was away from the computer was just for like five minutes, and they said no one got on my computer or anything.
So after I got back home, I was still signed in to Google Talk but when I tried to access Gmail, it only had my user name, but not my password. I went to the Google Account link from the Google page though, and it would let me access that. A little while after, it signed me out of Google Talk and I can't get back in since it requires inputting my password. So all I can access is account settings now.
Also, I scanned my computer for viruses, and there was a trojan, and also Ad-Aware detected a key logger. I'm actually thinking I know who's fault it is now, because my friend sent me a trojan last night, but I didn't have a virus scanner installed at the time (since I just reinstalled XP), so I opened it then, and didn't know it was a trojan until now. However, he's denying ever doing it, but if I got the file from his own web site, he would be the only one who could have stolen the account right?
I can't help it if you don't believe me, but first of all, I wouldn't hack into anyone's account anyway, and even if I wanted to, I could just install a key logger or something instead of going through this much trouble.
