To dream of a computer virus represents uncontrollable issues that frustrate you. Ideas or thoughts that cause irritability or anxiety. Feeling forced to think about something that you can't stand. Negative thoughts or feelings that seem impossible to get off your mind. Being got at by another person.
Example: A young man dreamed of his computer getting a computer virus. In waking life he feared embarrassing himself revealing his true feelings to a girl he liked. He felt that if he embarrassed himself with the girl he could never stop being like a idiot who is being noticed thinking stupid for having been honest about his feelings.
