notepad closes by itself and "only the best" pop up

hi, i've been hijacked, mi home page resets to about:blank, everytime i do a search in Google, another browser window opens with the url "http://search-to-find.com...", I get an "Only the Best" pop-up ad and to top it all, Notepad closes by itself.

I've used Adaware, Spybot, HiJackThis, AboutBuster and CWShredder, and nothing.
Maybe someone out there can help.....

here's my HijackThis Log file:

I'll appreciate any kind of help.

Your log shows that you are seriously behind on windows updates. It is essential that you update your windows before we continue to help you as the infections could reoccur. Go to http://www.windowsupdate.com and if it asks to install software, let it. Then click on the Scan link and let it do its thing. When its done you will see on your left a section called critical updates. Click on that section and install everything that you can. When it prompts you to reboot, do so. Then repeat this process again until there are no more critical updates listed. Then post a new log.
