My dad and mom have a Windows XP administrator account, and then mine is below theres… ?

Everytime I log on to my account, an error window that says “fAIL” (typed like that) pops up.

Whats goin on?

Either your family is trying to trick you and have fun, or there is an added file on your system. It could be a virus, but according to what you told me it does not sound like it. Are there any effects after the "fail" message? I would recommend a simple scan of the computer with AVG Anti-virus , or Norton Anti-Virus.

Do you log on ot not?
