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.
