Are this threats or a bug?

[beetof]

Using Spybot 1.6.2

Scanning in safe mode (XPpro) the program gives as result "No immediate threats were found".

Scanning in normal mode, immediately after the previous scan (no network), the result is:
- Adbrite
- Doubleclick
- Web Trends live
- Win32.PornPopUp
Clicking on 'Fix' gives 4 green checks.

But a new scan in normal mode gives the same result.

Why no threats are found in safe mode?
Why no threats are fixed in normal mode?
How to fix them?
Any idea?

These two are listed as tracking cookies:
Doubleclick
Web Trends live

These two I can't find listed,but I believe I remember them being detected as tracking cookies previously by Spybot:
Adbrite
Win32.PornPopUp
Do you have the latest detection updates?

I'm not sure why the third-party cookies aren't being found in safe mode.Since they aren't being fixed by Spybot in normal mode,you can remove them using your browser.This site shows you how to remove cookies in your browser,or has instructions for different browsers on how to remove specific cookies,if you prefer not to remove all cookies:
