how do I get rid of searchweb2 tool bars?

Hello,
I'm a newcomer. I got here through a google search on how to get rid of searchweb2 tool bars. I have been reading all what you have posted and even compared my HijackThis Logfile to the ones other users have posted. But so far I haven't dared to do anything as I'm afraid of deleting some important lines. Anyway, here is my HijackThis Logfile, hoping there's someone out there who can give me a hand.

Thanks in advance from Lisbon, Portugal
