It seems to be OK. There is a dllhost.exe*32 COM surrogate running by SYSTEM. But just 1. Scanning a photo went normally and they didn't reproduce a bunch of others. Thanks.

It is necessary to uninstall ComboFix :
  • Click Start (or
    VistaStartButton.png
    ) then Run.


    On Windows7 or Vista you may use Start Search field if Run is not available.
  • In the line of text type in (Copy) the following:

    Code:
    ComboFix /Uninstall
    Note that there is a space between " ComboFix " and " /Uninstall " .
  • then click OK (or press Enter ).

Wait for the uninstall process is complete.




=================================






The following will implement some post-cleanup procedures:

=> Please download DelFix by Xplode to your Desktop.

Run the tool and check the following boxes below;

Click Run button and wait a few seconds for the programme completes his work.
At this point all the tools we used here should be gone. Tool will create an report for you (C:\DelFix.txt)

The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.

I uninstalled combofix and downloaded and ran DelFix. Everything seems to be working fine.

I have 1 question. I still have a dllhost in the C:\windows\syswow64 folder and it starts whenever I restart the computer. it is in the task manager as dllhost.exe*32 COM surrogate. This is the COM surrogate from the exact location that was part of the virus. Should I be worried about this or is it a normal part of computer startup. Thanks so much for all your help.
