Windows start up problem – “AegisE5.dll was not found”

Hello there!
I am having a problem with my computer. Whenever I turn it on, an error message keeps on popping up saying “This application has failed to start because AegisE5.dll was not found. Reinstalling the application may fix this problem”, and the only way I could minimize it is through the Task Manager. I was hoping you could teach me where I can find AegisE5.dll and how I can reinstall it so that I’ll be able to fix it myself. I am looking forward to your response.
Thank you.
