Have split your post out to your own thread as it is too confusing to diagnose different logs in the one thread. Plus it is not fair on the original poster.

Download CWShredder from here & run it. Select the fix button & it will get rid of everything related to CoolWebSearch that is stored in it's database. Close ALL windows, including Iinternet Explorer, before running CWShredder. Reboot.

To help prevent this from happening again, install the patches for the vulnerabilities that this hijacker exploits by going here for your critical updates.

Reboot after doing this & post another log please.

HijackThis version 1.98 is out, so please update before posting.
