Your HijackThis (HJT) log is awfully short. Was it done in 'NORMAL' MODE as opposed to 'SAFE MODE'? Alternately, is it possible that you have put many HJT lines in the 'IGNORELIST' by using the 'Add checked to ignorlist'. That can potentially hide certain issues. Certainly, there is no real-time antivirus tool showing nor any indication of recommended tools like SpyBot:

Please download, install, update and scan your system with the free (trial) version of Ewido TROJAN scanner
[Developed for Windows 2000 and XP]:

1. When installing, under "Additional Options" uncheck "Install background guard" and "Install scan via context menu".
2. When you run ewido for the first time, you will get a warning "Database could not be found!". Click OK. We will fix this in a moment.
3. From the main ewido screen, click on update in the left menu, then click the Start update button.
4. After the update finishes (the status bar at the bottom will display "Update successful"), click on the Scanner button in the left menu, then click on the Start button. This scan can take quite a while to run, so time to go get a drink and a snack....
5. If ewido finds anything, it will pop up a notification. You can select "clean" and check the boxes "Perform action with all infections" and "Create encrypted backup" before clicking on OK.
6. When the scan finishes, click on "Save Report". This will create a text file. Please then paste the contents of the text file to this thread.

Note: Ewido is a free trial product for 14 days. Since Ewido is a trial version, the realtime guard and automatic update will stop functioning after 14 days. We are not installing the guard because it might interfere with the cleanup or the malware removal process. You can use Ewido as an on-demand scanner (recommended) but you will have to manually update the definition file each time you scan. If you decide to purchase Ewido, you can enable the 'Realtime Protect' and 'Automatic Update' functions by clicking on the 'Status' bar (Top left) and clicking on both items under "Your Security Status".

REBOOT.
