If you see strange things—toolbars, pop-ups, new programs you didn't have before—it's likely you've been hacked. Here's the point to all of this: If you're lucky, you've never been hacked. Or is it that it's already happened, but you're not aware of it?
Do you have any reason to believe your mac is hacked?
Have you installed any suspicious software recently?
Do you have someone with access to your mac who might install something without your knowledge (which requires them to have an administrative password and access to the system)
outside of that are you running any type of Mac Anti-Virus. If so most, if not all offering have been cited on these forums as points of failure on the Mac and in many, if not all cases removal of them restores system functionality and response. Reputable AV companies will post instructions to remove their products. At this time there are no known Mac Virus in the wild, meaning no securities lab in the world has posted any findings of a Mac virus that has shown up on the internet at this time, please do not confuse this statement with the absurdity of 'macs can't get viruses.', what I'm saying is 'they don't appear to have one yet, and mac AV is not nearly as flexible as it's windows counterpart and has been known to cause serious problems and not offer much of any protection'
secondly are you running any 3rd party system utility or network utility, again, these products are know to cause problem and are not only needed they commonly conflict with OS X, remove them from your system.
If you are unsure of what you are running please post an etrecheck report for the volunteers here to look further as to what your system is running, This report does not contain any personal or confidential information. the software was developed by a long time member of this forum with the primary purpose of helping mac users isolate a problem with their system and has had great success in doing this, an overwhelming majority of posts where it was asked attest to that.
