malware or virus?

I am running an iMac that has been upgraded to the OSX Yosemite.  This morning was doing some research for a medical procedure while in  their site up popped a picture and music with "Hacked by Turk Hack Team." I quickly got out.

Is there anything I should/should not do?  Also, what is this entity?  Is it a Trojan, or a virus or just malware?

You might have just gone to a website tha was hacked, or something could have actually infected you. All you have to to is run the free Adware Medic to see if you'te infected, and download the free Bitdefender Scanner

I'd be fairly sure it isn't your Mac .. it is a hacked website.  The chances of your mac being affected are very very slim.

Neither of the applications listed would be my recommendation to run on OSX.

If you have an anti-virus application on your computer - by all means run a scan .. if you don't have one try
