I have a nagging problem with a Trojan I can't seem to solve. The
Trojan appears to launch a program called win32.Difisim!downloader from
two locations: C:\WINDOWS\system32\chisel.exe
\Local Settings\Temporary Internet Files\content.IE5\89ABCDEF\MSLO7

Even though I have tried a number of programs to identify and eleminate
the problem, it persists. ETrust EZAntivirus is able to identify
win32.Difisim!downloader when it launches, and identifies the source.
And, EZAntivirus says that it has quarantined or deleted the program,
but it keeps reappearing.

Thus far I have tried the following programs without success:
Microsoft Antispy (beta)
Spyware Doctor
AdAware SE Personal
eTrust Pest Control
SpyBot Search and Distroy
Registry Mechanic

All fail to identify the Trojan or eliminate it. I have Downloaded and
run Hijack This, but I am afraid to make alterations in the registry
without knowing what I am doing. Below is my registry. Do you have any suggestions? This thing is nerve-wracking. EZ Antivirus keeps identifying it, says it is destroyed, then it reappears a few minutes later.
