OK, something strange is happening to my fb.?

[Jessica]

OK, something strange is happening to my fb. When I talk to someone on fb chat, it appears that i am sending the word "ok" constantly to the person i am talking to. But if i ask the person if he sees the "ok" he's telling me that he doesn't se anything. But if i look at the whole conversation after i refreshed the page , the word " ok" doesn't appear, but it shows up again at the begining of the conversation, as i have wrote and sent it. If i enter someone elses fb, i can see the word has been sent, by me, but only at the begining, not in the whole conversation. So it must be some kind of virus, or something is wrong with my laptop? Can someone give me some advice?
Thanks

No virus, its probably just one of Facebooks glitches

Maybe it's something wrong with Facebook. Just try to log off and it may refresh or something.

you probably installed some malware on your computer... most likely a toolbar or a browser extension

do you use torrents to steal music?

It looks like you might have installed some malware on your computer
