    I've just ran Ad-aware, and it said that my computer has been affected by:

    win32.Trojan.Dnschanger


    How do I remove this? I've seen a lot of people with this problem, but I don't know if it's the same way to remove it.


    Thanks~

    Click here to download HJTsetup.exe:

    http://www.thespykiller.co.uk/forum/index.php?action=tpmod;dl=item5
    Scroll down to the download section

    Save HJTsetup.exe to your desktop.

    Double click on the HJTsetup.exe icon on your desktop.
    By default it will install to C:\Program Files\Hijack This.
    Continue to click Next in the setup dialogue boxes until you get to the Select Addition Tasks dialogue.
    Put a check by Create a desktop icon then click Next again.
    Continue to follow the rest of the prompts from there.
    At the final dialogue box click Finish and it will launch Hijack This.
    Click on the Do a system scan and save a log file button. It will scan and then ask you to save the log.
    Click Save to save the log file and then the log will open in notepad.
    Click on "Edit > Select All" then click on "Edit > Copy" to copy the entire contents of the log.
    Come back here to this thread and Paste the log in your next reply.
    DO NOT have Hijack This fix anything yet. Most of what it finds will be harmless or even required.

    Please disable WordWrap in notepad before posting any new logs. Otherwise the logs are unreadable.
    (Notepad -> Format -> uncheck WordWrap)

    Please download FixWareout from one of these mirrors:
    http://www.bleepingcomputer.com/files/lonny/Fixwareout.exe
    http://downloads.subratam.org/Fixwareout.exe

    Note: You must have an active Internet connection when running this fix, in order to download the Brute Force Uninstaller (BFU).

    Save it to your desktop and run it. Click Next, then Install, make sure "Run fixit" is checked and click Finish.
    The fix will begin; follow the prompts. If your firewall gives an alert, (because this tool will download an additional file from the internet), please don't let your firewall block it, but allow it instead.
    Then you will be asked to reboot your computer; please do so. Your system may take longer than usual to load; this is normal.
    Once the desktop loads please post the text that will open (report.txt)
    ==========================

    Download Superantispyware

    http://www.superantispyware.com/superantispywarefreevspro.html

    Install it and double-click the icon on your desktop to run it.
    · It will ask if you want to update the program definitions, click Yes.
    · Under Configuration and Preferences, click the Preferences button.
    · Click the Scanning Control tab.
    · Under Scanner Options make sure the following are checked:
    o Close browsers before scanning
    o Scan for tracking cookies
    o Terminate memory threats before quarantining.
    o Please leave the others unchecked.
    o Click the Close button to leave the control center screen.
    · On the main screen, under Scan for Harmful Software click Scan your computer.
    · On the left check C:\Fixed Drive.
    · On the right, under Complete Scan, choose Perform Complete Scan.
    · Click Next to start the scan. Please be patient while it scans your computer.
    · After the scan is complete a summary box will appear. Click OK.
    · Make sure everything in the white box has a check next to it, then click Next.
    · It will quarantine what it found and if it asks if you want to reboot, click Yes.
    · To retrieve the removal information for me please do the following:
    o After reboot, double-click the SUPERAntispyware icon on your desktop.
    o Click Preferences. Click the Statistics/Logs tab.
    o Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    o It will open in your default text editor (such as Notepad/Wordpad).
    o Please highlight everything in the notepad, then right-click and choose copy.
    · Click close and close again to exit the program.
    · Please paste that information here for me with a new HijackThis log.

    Hmm, well I have this issue with my computer right now still, where it freezes when I play a game. After a few seconds, it automatically restarts my computer again. I am not sure why that is. I know that the virus is gone now, but this still occurs. Is it possible that my power supply isn't strong enough to support my computer?

    Thanks by the way for helping me with this issue~

    Make sure the PC is clean on the inside and all fans are running


    DownLoad EasyCleaner http://www.majorgeeks.com/download414.html

    Use the clear files and Unnecessary files buttons – I do not recommend
    using the Duplicates files button
    as many dupes are there on purpose.

    Not all files will delete – that is normal.

    In the unnecessary button I check the top 4 entries
