Definition: An annoyance is a piece of malware which leans more toward mischievous than malicious. These often come as email attachments from friends who think it will be funny to pull a prank on you. Executing files such as this, often leads to silly, but non-destructive, actions such as opening the CDROM drive on your computer or flipping the text on your screen backwards or upside down.

Also Known As: joke, hoax


About Author

I have a passion for technology and gadgets--with a focus on Microsoft and security--and a desire to help others understand how technology can affect or improve their lives. I also love spending time with my wife, 7 kids, 3 dogs, 4 cats, 3 rabbits, 2 ferrets, pot-bellied pig and sulcata tortoise, and I like to think I enjoy reading and golf even though I never find time for either. You can contact me directly at For more from me, you can follow me on Twitter, Facebook, Instagram and LinkedIn.
