I just downloaded Ad-Aware 2007 (free version) and ran a scan. As I was removing infected files, this message popped up:

"An error has occurred in Ad-Aware 2007!

Component:
TVirtualStringTree

Message:
Access violation at address 00537FEC in module 'Ad-Aware 2007.exe.' Read of address 000000D

Send this information to Lavasoft Support Team...

Ad-Aware Terminates."

What should I do?

That error is often cause by an infection that has attacked the Ad-Aware program itself to evade removal.

Please download this free tool to make a diagnostic log for review and manual removal help.

* Download Trend Micro Hijack This™
http://download.bleepingcomputer.com/hijac.../HJTInstall.exe
Doubleclick the HJTInstall.exe to start it.
By default it will install HijackThis in the Program Files\Trendmicro folder and create a desktop shortcut.
HijackThis will open after install. Press the Scan button below.
This will start the scan and open a log.
Copy and paste the contents of the log in your next reply.

{moving this topic to the "Help I'm Infected" forum}

I have the same error message. Here is my log file:..
