KillAV.HN and various others infection

Your logs look clean...but I need to ask what these are:
C:\Documents and Settings\Administrator\My Documents\js56nen.exe ----> I don't know why it is where it is.

You only need to use add/remove programs to uninstall:
J2SE Runtime Environment 5.0 Update 6

Now Please download ATF Cleaner by Atribune. This program does not require an installation. The executable actually runs the program.

NOTE: This program is for Windows XP and Windows 2000 only. ATF Cleaner will remove all files from the items that are checked so if you have some cookies you'd like to save. Please move them to a different directory first.

* Double-click ATF-Cleaner.exe to run the program.
* Under Main choose: Select All
* Click the Empty Selected button.

If you use Firefox browser

* Click Firefox at the top and choose: Select All

If you are not having any other malware problems, it is time to do our final steps:

1. If we used ComboFix then UNINSTALL COMBOFIX (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
2.
* Click START then RUN
* Now type "%userprofile%\Desktop\cf" /u in the runbox and click OK.
* Note: The space between the cf and the /U, it must be there.
3. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
4. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
5. If you are running Windows XP or Windows ME, do the below:
* Refer to the cleaning steps in the READ ME for your Window version and see the steps to Disable System Restore which will flush your Restore Points.
* Then reboot and Enable System Restore to create a new clean Restore Point.
6. After doing the above, you should work thru the below link:
