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

    Your computer is clean [​IMG]

    1. We need to reset system restore to prevent your computer from being accidentally reinfected by using some old restore point(s). We'll create fresh, clean restore point, using following OTL script:

    Run OTL

    • Under the Custom Scans/Fixes box at the bottom, paste in the following:

    Code:
    :OTL
:Commands
[purity]
[emptytemp]
[EMPTYFLASH]
[emptyjava]
[CLEARALLRESTOREPOINTS]
[Reboot]
    • Then click the Run Fix button at the top
    • Let the program run unhindered, reboot the PC when it is done
    • Post resulting log.

    2. Now, we'll remove all tools, we used during our cleaning process

    Clean up with OTL:

    • Double-click OTL.exe to start the program.
    • Close all other programs apart from OTL as this step will require a reboot
    • On the OTL main screen, press the CLEANUP button
    • Say Yes to the prompt and then allow the program to reboot your computer.

    If you still have any tools or logs leftover on your computer you can go ahead and delete those off of your computer now.

    3. Make sure, Windows Updates are current.

    4. If any Trojan was listed among your infection(s), make sure, you change all of your on-line important passwords (bank account(s), secured web sites, etc.) immediately!

    5. Download, and install WOT (Web OF Trust): http://www.mywot.com/. It'll warn you (in most cases) about dangerous web sites.

    6. Run Malwarebytes "Quick scan" once in a while to assure safety of your computer.

    7. Run Temporary File Cleaner (TFC) weekly.

    8. Download and install Secunia Personal Software Inspector (PSI): http://secunia.com/vulnerability_scanning/personal/. The Secunia PSI is a FREE security tool designed to detect vulnerable and out-dated programs and plug-ins which expose your PC to attacks. Run it weekly.

    9. (optional) If you want to keep all your programs up to date, download and install FileHippo Update Checker.
    The Update Checker will scan your computer for installed software, check the versions and then send this information to FileHippo.com to see if there are any newer releases.

    10. (Windows XP only) Run defrag at your convenience.

    11. When installing\updating ANY program, make sure you always select "Custom " installation, so you can UN-check any possible "drive-by-install" (foistware), like toolbars etc., which may try to install along with the legitimate program. Do NOT click "Next" button without looking at any given page.

    12. Read How did I get infected?, With steps so it does not happen again!: http://www.bleepingcomputer.com/forums/topic2520.html

    13. Please, let me know, how your computer is doing.

    Unsure whether I have to do something about step 4

    My PC seems to be doing fine, no trace of the initial problem, and it seems I might have shaved a few seconds off boot time, but I haven't timed it so who knows.

    Only mystery is a new process I get in the task manager - dfsvc.exe, I've never before seen it run, and I regularly check.

    It looks like a part of .NET Framework.

    Let's see....

    Please download SystemLook from one of the links below and save it to your Desktop.
    Download Mirror #1
    Download Mirror #2
    64-bit users go HERE
    • Double-click SystemLook.exe to run it.
    • Vista users:: Right click on SystemLook.exe, click Run As Administrator
    • Copy the content of the following box and paste it into the main textfield:
      Code:
      :filefind
dfsvc.exe
    • Click the Look button to start the scan.
    • When finished, a notepad window will open with the results of the scan. Please post this log in your next reply.
    Note: The log can also be found on your Desktop entitled SystemLook.txt
