I have completed all steps from the preparation guide. I keep getting error messages that read "DLL C:\WINDOWS\System32... is not a valid Windows image, please insert your installation diskette." I have no idea what kind of virus, etc. this is. I installed Service Pack 2 for Windows XP weeks ago, before I ever thought there might be a problem. I tried to uninstall but can not find it in the Add/Remove Programs list. When I tried to do a Search, I received a message that "a file needed to run Search Companion cannot be found. You may need to run setup." At that time, I again receive the error messages mentioned above.
Thank you advance for your help!

Welcome to the BleepingComputer HijackThis Logs and Analysis forum KAyA
My name is Richie and i'll be helping you to fix your problems.

You have a Backdoor Trojan present on your pc
A Backdoor is a software program that gives an attacker unauthorized access to a machine and the means for remotely controlling the machine without the user's knowledge. A Backdoor compromises system integrity by making changes to the system that allow it to by used by the attacker for malicious purposes unknown to the user.

They are typically installed without user interaction through security exploits, and may allow an attacker to remotely control the infected machine. Such risks may allow the attacker to install additional malware and use the compromised machine to participate in denial of service attacks, spamming, and bot nets, or to transmit sensitive data to a remote server. The malware may be cloaked and not visible to the user. These risks severely compromise the system by lowering security settings, installing 'backdoors,' infecting system files, or spreading to other networked machines.

If your computer was used for online banking or has credit card information on it, all passwords should be changed immediately to include those used for email, eBay and forums.
You should consider them to be compromised.
They should be changed by using a different computer and not the infected one,if not an attacker may get the new passwords and transaction information.
Banking and credit card institutions should be notified of the possible security breech.

Since your computer was compromised read:

When Should I Format, How Should I Reinstall:

Let me know how you wish to proceed in your next reply.

After reading the material, I believe I need to re-format my computer. Just before this problem started, my computer had been recently reformated by Gateway so there is very little information of importance on there. I am concerned, however, that I may have used the computer to access banking account information or to make purchases with my credit card. Thus, I will follow the steps to avoid identity theft.
If I am not comfortable doing the re-format, re-install by myself, is there somewhere I could take my laptop? Unfortunately, my Gateway warranty has ended.
Please let me know what my next steps should be.
Thank you!

When you first got your laptop,did you get the Microsoft Windows XP installation disk,or any system recovery cd's.
If you did then i suggest you refer to your laptops documentation/handbook for help with the task,or contact your laptops manufacturer.
Failing that,do you have a knowledgeable relative or friend who could perhaps reinstall/recover the operating system for you.
