Robin,
Why would you think this file is showing in your log here;
O4 - Global Startup: Adobe Reader Speed Launch.lnk = C:\Program Files\Adobe\Acrobat 7.0\Reader\reader_sl.exe

As Gizmokid points out this IS a legitimate entry, nothing unusual about it. It is seen daily in many, if not most HJT logs.
Can you do another Spybot scan and post the log for us? or at least give us the exact wording of each item found?
You never mentioned Clearsearch, and now you say it finds it everytime too...
while it is scanning CoolWWWSeach files...
where does it find it? There should not be ANY CoolWWWSearch Files on the computer. Nothing like that is showing in your HJT log. Any of your logs.
None of these items are showing in your logs.
