Unknown problem: Can't run Ewido & Spybot SD

I am now using another computer. My PC doesn't allow me to run Ewido and Spybot SD. It even stops me from link to this forum and thus I am not able to post the Hijack This log here. I posted the Hijack This log on Bleeping Computer forum but haven't received any help so far.

I scanned my PC by Adaware. One item has been identified but it couldn't be removed. What should I do? Pls help.
