Windows 7 Issue on Task Scheduler

I am running Windows 7 on my computer system, but an issue occurred related to Task Scheduler.
The error message says, “The task image is corrupt or has been tampered with. ”
This was the first time that I have encountered this kind of error.
This error keeps on bugging me, and I have no idea on how to get this error fixed.
Please help me to resolve this issue.
