Chaslang, please help. My Hijackthis is missing something

I've been using Hijackthis for a while since my uncle set it up for me. I've been using it and has made my computer faster, and life easier, but now(after running adaware) I'm somehow missing a file. Here is a picture of the message: http://img137.echo.cx/my.php?image=htjproblem23yw.jpg

Someone please help, as now i'm downloading firewalls and such to help my computer, Hijackthis was the best one and made my computer faster. The .exe file is reccamended if I need to download/install it again.

 

Nevermind, please close this topic, i solved my problem.
