"Karen's Virus" is a SpongeBob SquarePants episode from season eleven. In this episode, Karen gets a computer virus, and it's up to SpongeBob to get it out of her.



The episode starts with Karen having lunch with her friend, Hanna. She sneezes on Karen and tells her to go home and get some rest. Afterwards, Karen gets a virus in her system after Hanna spreads her bug on her databanks. Plankton then sees SpongeBob outside the Chum Bucket, banging a hammer that's on his head on the door. Plankton tells SpongeBob that Karen needs help, so they try to come up with names for the mission they are going to do. They choose to name it Operation: Saved Karen. Plankton then inserts SpongeBob into Karen's hard drive.
