Spybot Search & Destroy Not Fixing Problems

[wenpeek]

I ran a Spybot search oon my computer and I selected all the items that I wanted removed and hit "fix selected problems" and received the following error:

Unexpected error in fixing problems
(Date:"C:\Windows\System32\Drivers\etc\hosts" kann nicht erstellt werden. The process cannot access the file because it is used by another process)

The problems that were not fixed or removed are:

eZula HotText: Class ID
eZula HotText: Type Library

CoolWWWSearch.SmartSearch: Redirected host (Redirected host nothing done)

Download Accelerator Plus ads: Default ad category (Registry change, nothing done)
Download Accelerator Plus ads: Ad category (Registry key, nothing done)

I uninstalled Download Accelerator Plus a long time ago but this keeps coming up everytime I run Spybot but I can never remove it.

Any advice on this would be greatly appreciated. ::
