Re: Does this HJT log look suspicious?

Even though the Virus Total results show nothing detected, I don't like the fact that winlogon.exe was recently modified, nor the MD5 listed with it:

As such, I think it prudent to replace it with a known good copy from your system.


Please copy this page to Notepad and save to your desktop for reference as you will not have any browsers open while you are carrying out portions of these instructions.

It's IMPORTANT to carry out the instructions in the sequence listed below.

***************************************************

Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

---------------------------------------------------------------------

**NOTE**
This time around, be sure to allow ComboFix to install the Recovery Console. If the installation fails for any reason, click 'No' when prompted if you want to continue. Then come back and tell me of the error you received.

Open notepad and copy/paste the text in the code box below into it:

Quote:
FCopy::
c:\windows\ServicePackFiles\i386\winlogon.exe | c:\windows\system32\winlogon.exe
Save this as "CFScript.txt", and as Type: All Files (*.*)
in the same location as ComboFix.exe





Refering to the picture above, drag CFScript into ComboFix.exe

When finished, it shall produce a log for you at C:\ComboFix.txt
