Malicious dll problem

[laguano]

 have a log from hijackthis, it isn't my computer. The person uses Internet Explorer (:p) and trend micro notified him about a Malicious file.

O2 - BHO: (no name) - {5118E9B7-6D4A-4C18-910D-67BBE35B094E} - C:\WINDOWS\system32\dbnmpnt.dll

that is from the hijackthis log, every attempt to get rid of this. (spybot, hijackthis, adaware, trend micro, etc..) has failed, i was wondering why even hijackthis cannot "fix" this file. Thanks for anyone's help.

mishankar - log is clean

laguano -  you need to take out the file as well as the HJT entry but more work will probably be needed -try this

Download and then run SuperAntispyware

• On the first page select Check for Updates
  
• On completion select SCAN YOUR COMPUTER
  
• On the next page select COMPLETE SCAN and tick ALL your drives
  
• The next stage will take a while as your entire drive(s), memory and registry are scanned
• When it has completed click NEXT
  
• The next screen shows the problems found click OK
  
• On the next screen place a tick against all items and select NEXT
  
• Now to get the log Go to the PREFERENCES button on the right bottom
  
• Select the STATISTICS/LOG tab
  
• Highlight the scan just completed and click VIEW LOG
  
• This will open a notepad text file copy and paste this to your next reply
