Before you do anything please go in and STOP AdAware service from running on the computer. This could interfere with any fixes attempted. Also turn off AVG Anti-Spyware 7.5. This program can actually be uninstalled as it is out of date and no longer supported and also could interfere with attempted fixes. The newest version is now contained within AVG 8 antivirus program. Turn off that Spyware Hunter program also. This could interfere also. Also, this does not appear to contain an antivirus program or firewall.
One thing you are showing on the log is the VistaAntivirus2008 program which is a Rogue anti-spy program. You need to do the following which WILL remove this and other items, maybe not all but if we can get this thing off there then maybe we can get busy on some of the other scans you need to do;
Please download Malwarebytes' Anti-Malware (MBA-M) to your Desktop.
* DoubleClick mbam-setup.exe and follow the prompts to install MBA-M.
* Be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform full scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When MBA-M finishes, Notepad will open with the log. Please save it where you can find it easily. The log can also be opened by going to Start > All Programs > Malwarebytes' Anti-Malware > Logs > log-date.txt.
You also do not appear to be running either an anti-virus program or a firewall. Both of these are absolute musts. There are several good free ones of each available noted in this sticky at the top of the page PC Protection - How To Avoid Infections . The choice is yours but pick one of each and install and use them ALWAYS.
Once you have run and cleaned whatever is noted by the Malwarebytes' Anti-Malware program then reboot and run HiJackThis and place checkmarks next to the following entries if they still exist;
