Start HijackThis and run another scan. Place a checkmark next to this item:
O20 - Winlogon Notify: sbicjeck - sbicjeck.dll (file missing)Close all other windows and click on Fix Checked. That should now be gone.
Also, you need a firewall. You're vulnerable without a firewall, so you should look into getting either
ZoneAlarm,
Kerio Personal Firewall, or
Comodo. They're all good free firewalls. Just be sure you only have
one installed at a time! Download the firewall of your choice, disconnect from the internet, disable Windows Firewall, and install your new firewall.
Other than that, I don't see anything wrong.
