Read your other question.

Honestly, if you didn't get all of that other stuff fixed, your OS is badly infested and I don't really see you getting out of this unless you can articulate exactly what's going on.

The time and date given on those hijack logs is super old. Were those old logs you posted, or have you manipulated the time and date on your PC? Perhaps you are using a pirated version of XP then?

Read this for your registry problems - How to Repair the Windows Registry (http://www.easydesksoftware.com/howto.htm)

Your PC may have come with a Recovery CD or partition that will return the system to factory settings. You can also try seeing if you have a Restore Point under System Restore.

the date on the hijacks is old because when I want to change the date it would said the rundll32.exe is missing or damaged.
