Strange Adobe activity

Best to rule out malware ...

Download and run Malwarebyyes Anti-Malware for Mac formerly known as AdwareMedic. It's free.

Make sure Mac App Store and identified developers is selected in System Preferences > Security & Privacy > General

If you would rather not download Malwarebytes Anti-Malware, you can remove the malware manually following the instructions here > Remove unwanted adware that displays pop-up ads and graphics on your Mac - Apple Support

Abode showed up on my dashboard. Did not open or prompt to upgrade. I closed by using launcher. Computer has slowed and tonight music started playing as I read as e-mailed. Has my Mac been hacked? What can I do?

Do you use the Acrobat reader? If you do and recently loaded adobe acrobat from a third party site you may have loaded a hacked version.

Never ever load Acrobat from a third party site.

Can you be more specific about what you're seeing? A screenshot would be very helpful.
