It 's obvious you did not get the variants I am speaking about and you are
no Registry "expert" ;)
For those variants :
HijackThis let you see the entry
(and in most case with no value) BUT when you delete it and click refresh,
it comes immediately back for the trojan is still running.
If you kill the associated running random name dll (for instance
c:\windows\system32\logb.dll) it comes back at next reboot and adds the
value AppInit_DLLs again in the registry.
To get rid of it, you have to rename the key
HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Windows in Windows2 ,
then delete the entry AppInit_DLLs which seems not having any value. When
done, rename the key with its regular name and AppInit_DLLs will not appear
anymore when refreshing ; only when it's done you will be able to kill and
delete the random name.dll for good which is the Backdoor.Agent.ba used to
install this tricky variant of CoolWebSearch.
That's why I said HijackThis has its limits : suppressing the entries its
log gives directly from the registry does not help.
That's just an exemple, the are other variants which add in the registry the
entry AppInit_Dlls somewhere else with the same result and the same way to
get rid of it.
Hoping it's clearer now, so sorry for my poor English.
