Syware/Virus problems

Hello all, this is my first time using this site and posting a thread. I am having troubles with what I believe to be a mixture of spyware and viruses on my computer. The main problem I have is that my homepage is set to google but instead of pulling up google it pulls up a page stating my computer is infected with spyware and to buy various removal tools. This makes it impossible for me to pull up google. Also, if I used yahoo or other search engines, once I try to click on the link to the page I want to go to, the virus pulls up a different unrelated page. Also getting ads showing up in website pages that normally do not have adds. I have fun CC Cleaner, Windows Malicous Software Removal Tool, AD Aware SE Personal, Spybot Search and Destroy, Microsoft Windows Defender, CW Shredder, Bitdefender, Panda Active Scan, and Hijack This but I still am having the problem. I have attached my log files from PandaActive Scan, Bitdefender, and Hijack This below. Any advice on how to resolved this would be most appreciated. Thank you to all that reply!

HijackThis is install incorrectly. Move HijackThis to C:\Program FIles\HJT. Do this before you do anything else.

The installed version of Java on you computer is out dated. Install the latest version, which is 1.5.0_06, uninstall the old version.

Follow the directions for SpywareQuake & SpyFalcon Removal Procedure.

Post the smitfiles.txt and a fresh HijackThis log.
