What should I do if I think someone else has access to my Facebook account.?

[dimend5]

Okay so I feel like someone else is using my facebook account because I get these game notifications of games I have never even seen before. They haven't posted anything on my wall or anything I think they are just playing games or something. Because when I signed up for a game that I have never played before it said that the Facebook Id was already in use. Should I just shut down my account?
I already tried changing my password. I still think the person has access to my account

Or try changing your password...

Change your password! Easy as that. Make it completely different, something they never will guess. That happened to me once so I changed my password to stophackingmyfacebook. Trust me, they will never guess something like that and if they do, change it again.

Change the e-mail address you use to log in to Facebook and then change your password again.

If you Changed your Password your Next Step is to Change your Email Address if you Still Suspect After that That Someone is Using your Account you Can Check and See if there is any Active Sessions Going on Go to Account Settings Go to Security than Go to Active Sessions and it will Tell you Where your Facebook Has Been Logged into if you See Any unauthorized Devices you Can Shut them Down By Clicking on End Session

After doing what Daniel suggests, make sure your computer is free of any keylogger or trojan virus on your computer. Update your security protection and then get off the internet completely, cut off your internet connection and run your security scans to detect any virus. If you have any infections make sure they are quarantined or removed. Do the scans twice to be sure. Then get back on the internet and access facebook, and you can secure your facebook account - read here on the fb help page - look under >My account is hacked.

For the next week or so, log out of facebook every day and use your new password to get back in each day. That will protect you additionally and if someone does access if will be clear.
