still having issues after tr/crypt.xpack.gen removal

It's not too bad. Let's just do this:

First, what is this:
C:\Documents and Settings\yfl ?

Please use add/remove programs to uninstall:
J2SE Runtime Environment 5.0 Update 10"
J2SE Runtime Environment 5.0 Update 8"
Java 2 Runtime Environment, SE v1.4.2"
Java(TM) 6 Update 11"
Java(TM) 6 Update 2"
Java(TM) 6 Update 3"
Java(TM) SE Runtime Environment 6 Update 1

Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator). This is really HijackThis (select Do a system scan only) and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:

After clicking Fix, exit HJT.

Now Copy the bold text below to notepad. Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.

Make sure that you tell me if you receive a success message about adding the above
to the registry. If you do not get a success message, it definitely did not work.

Now use windows explorer to find and delete:
c:\windows\fdgg34353edfgdfdf
c:\windows\Phujusocacezafit.dat

Now reboot and install:
Java Runtime 6

Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator).

Then attach the below logs:
* C:\MGlogs.zip

Make sure you tell me how things are working now!
