First, thanks for reading this. I did read and attempt to go through the steps listed in the Malware Removal Guide. However, although I could download the file for CCleaner, I could not make it run. I have a new (I've had it for less than a month) HP laptop running Windows 7. I somehow acquired a Trojan, despite having Norton AntiVirus running on my system. I downloaded a few set-up files for programs such as HijackThis and Cleaner7, but I cannot run any of them. I get the "is not a valid Win32 application error" when trying to to do. I restored my laptop to the original factory settings, but that didn't help. Because I did this, I lost the name of the evil program (I had searched Google for it)... the name sounded something like "animal", and it pretended to find threats on my computer in order to get me to pay for "removal" of them. I tried to remove it in my control panel but of course that didn't work. I thought that since it didn't show up in Programs when I restored it was gone, but I could tell my computer was still infected.
