What should i do ?

Did you have the browser closed when you fixed them???? Must be closed. If you did
Try running CWShredder. Download CWShredder from http://209.133.47.200/~merijn/files/CWShredder.exe & run it. Select the fix button & it will get rid of everything related to CoolWebSearch. Close ALL other programs including IE before running CWShredder. Reboot after doing this & post another log please.

Hey , i had a IE window opened at the time.

All went smoothly this time and everything is fixed!

Thanks for your help!!

No worries. Glad it was an easy fix.
