no, you have a virus
look here: http://osbot.org/forum/topic/4963-hacked/
also did you download the client from osbot.org main page? any other place is not safe and very likely to contain malware.
i suggest running a malwarebytes scan, if there is a virus it will find it http://www.techspot....ti-malware.html. also what script were you using?
@cooper88 do you have jagex account gaurdian on eoc?
