Now, close all instances of Internet Explorer and any other windows you have open except HiJackThis, click "Fix checked".

===============

Locate and delete the following item(s), if present. Make sure you are able to view system and hidden files/ folders:

folders...

C:\PROGRA~1\COMMON~1\zooz

-

Note that some of these file(s)/folder(s) may or may not be present. If present, and cannot be deleted because they're 'in use', try deleting them in "Safe Mode".

-

Reboot.

===============

To help protect your system from hostile ActiveX content, or special 'downloadable' files:

Download, install and keep updated, SpywareBlaster. If you've installed it for the first time:

1) Check for any available updates; if present, they'll be automatically downloaded and installed.
2) Next, "Enable all protection".
3) Exit the program.

-

Note: Remember to regularly check for updates.

===============

After rebooting, rescan with hijackthis and post back a new log. Please let me know how your pc is now.
