Suspicious 'facebook' plugin with no info about it online

Hi, sorry if this is the wrong newsgroup for this.

I got my facebook account hacked the other day, which was extremely alarming as I'm very careful with my security info, and I believe I tracked it down to a suspicious facebook plugin that somehow got installed. Since I couldn't find any info at all online I was wondering if anyone here would be interested, or if someone could direct me to someone who would like to check it out.

Maybe I should send it to the big security software vendors?

Thanks,
