I see you have more than one Anti-Virus program installed, Avast and Bitdefender. While this may seem like greater protection, it can cause problems including slowdowns and system hangs. Choose one to keep and uninstall the other.

Any antivirus program must be removed via add/remove program.
For any program that doesn't have an add/remove entry, you will have to do this:

re-install the program -> reboot -> uninstall

Please visit this webpage for instructions for downloading and running ComboFix. Take your time and read the page completely. If there's anything you don't understand, post back and ask questions first, before proceeding.

If, while you're performing those instructions, you need to install the Windows XP Recovery Console using ComboFix, a log will be produced, CF-RC.txt

Post that log before continuing any further, and do NOT reboot your machine until I've reviewed it.

If you have a Windows XP CD with which to install the Windows XP Recovery Console as directed in the Guide, or already have the Windows XP Recovery Console installed, post the log from ComboFix when you've accomplished all that, along with a new HijackThis log.
