Asianpanthers, first you need to go to Window Update to get the Critical Updates for your computer. Hold off on SP2, however, until your system is clean.
Next, you are currently running hijackthis from a temp folder; you need to put hijackthis into it's own permanent folder (like c:\hjt\hijackthis.exe). The reason for this is part of cleaning your system may require all temporary folders to be cleaned out; also, hijackthis puts it's backups into the same folder where it is installed, so your backups will be at risk of being deleted as well.
After you put hijackthis into it's own folder, close all browser windows, scan with HJT, and post a new log please.
