Strange happening with facebook

After I logged out of MG about an hour ago I went to yahoo briefly, then to facebook. When I tried to log in I got a message saying my account was temporarily locked. It said that it was because I was logging in from a device I'd never logged in from before. But that is totally untrue as I only use the computer I am on and have never logged in from anything else. Nor have I used profanity or threatened anyone on there, so on. I barely do anything on facebook and have almost no profile. I wonder if this is a ploy to get more into my business. Why would they think I was logging in from a different device? Would appreciate any input on this.

Sounds like someone reported your account.

Why would they? I barely have a presence on Facebook. I don't flame or curse or threaten, so on. I use it to keep up with some relatives and friends on there. And why would the message then, say they are doing it because they detect I am signing in from a different device from usual. Also, they wanted my birthdate and for me to scan my id for them online. I'd never do that. As well, when I just signed in to MG, and was typing in my password, a wide red line appeared on the left bottom of the screen with my password in it. So I am wondering what is going on.
I am worried someone has hacked me. How can I find out?

Are you on a dynamic IP address? If so, your IP address may have changed, and Facebook "thinks" you are logging in from a different device or location.

 

To add on to what pwillener stated, have you done any malware and spyware scans for such things as a backdoor trojan or a keylogger ? Also, have you changed your passwords or found some passwords not working ?

 

pwilliner,
I have a cable connection and my ip changes whenever I reconnect to the net. I don't leave it always on ever. I change daily, so Facebook should be aware of that. They said before that that I was logging in from a different 'device', too. At first they wanted my birth date [which I never tell] and a picture of my state id, and over an unencrypted connection at that. I would never give that on line, even if encrypted. I thought it might be some scam. But the next day I got back into my account. They asked if I'd logged in from town in my state, and gave the time, I said that I'd logged in at that time. They have no phone no. so resolving these things is awful. But I left feedbacks, which they never responded to. I told them they had to know that isps could have servers all over one's state, and even out of state, and I again asked them to let me know what was really going on, to no avail. Anyway, I am back in, but very odd experience.

Thanks Laura,
I have gotten back in. They just asked me the day after to verify that I was the one trying to log in the day before and I did. I just use facebook to keep up with people I know at a distance.

 

Laura,
I don't think I have enough technical ability to do the read and run thing. I run daily scans, and so far they are clean, and I know there could still be problems. I just very recently had the computer checked and the tech said he was surprised at how good running and clean of bugs, ect my 'museum piece' was.

 

Nick t,
I have done daily scans and also rootkit scans. My passwords work, I did do some changing, but they all work. What would I use to scan for keyloggers and trojans. I have a fairly common antimalware/spyware program,that I use alot daily, but don't know if it catches keyloggers and trojans. Would a keylogger be able to remotely get into my machine, because the tech I had look over my computer recently [he declared it clean] looked inside because I asked him to look for anything that shouldn't be there, and there was not anything.
