Trojan help please

here is what is going on.

I ran my virus scan (AVG 7 pro) and it returns a virus located in my temp folder called psw.agent.3.an. my program deletes it but then it reappears. I have manually deleted from my computer in Normal mode, safe mode, and dos. But it reappears everytime. I am running winxp pro sp2. i even have tried to rename the file but then it creates another file that is the original. The file is called yekbil.dat
also
I have run hijackthis and have noticed an entry that is *libkey
that is not usually in the list, but when i try to delete it, it too comes back even in the registry. I have run ad-aware on the computer and it is clean. I even tried The Cleaner program but no luck. I have also turned off System restore, and deleted the _restore directorary

Any suggestion


Thank you

 

Have you removed any suspicious entries in the Run key in the registry for both HKLM and HKCU? How about in win.ini file? Startup folders?

 

In safe mode, delete the contents of all temp folders.
C:\Temp
C:\Windows\Temp
C:\Windows\Prefetch
C:\Documents and Settings\username\Local Settings\Temp........do this for all usernames.....local settings is a hidden folder, so you will need to show hidden files and folders
control panel>internet options......delete temporary internet files, including offline content
control panel>Java Plug-in>cache tab, click clear........if you have Sun Java installed
Empty the recycle bin

Reboot to Windows and run Panda ActiveScan. If still infected, post a HijackThis log.
