    [Active] msa.exe, b.exe

    HI guys I think I have got something really nasty of the internet when I logged on to my computer today I saw alot of popups and my laptop was running slow.

    SO i opened windows task manager and saw msa.exe running which i ended I also then went to my c:/documents and settings/user/local settings/temp and saw the following programs b.exe and c.exe along with msa.exe they didnt look right so I deleted all of them and thought that was the end of it.

    But this was not the case I am still getting pop ups, google is redirecting to **** sites etc so then i realised i had to do something so I ran AVG in safe mode and try to run Malawarebytes anti malaware. AVG ran a scan and found alot of locked files but didnt find any infections etc. Malawarebytes started up ran for 5 secs and dissapeard when I try to start it again it said it couldnt acess the specified device, path or file <--- this was in safe mode as well.

    Also when I try to acess alot of my main folders like c:/documents and settings its saying acess denied.

    I am running Windows Vista on SP1 what do I do next please help....

    Please download ComboFix from [color= "Red"]Here[/color] or [color= "#FF0000"]Here[/color] to your Desktop.

    **Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**
    1. Please, never rename Combofix unless instructed.
    2. Close any open browsers.
    3. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
      • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results ".
      • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
      NOTE. If Combofix asks you to install Recovery Console, please allow it.
      • Close any open browsers.
      • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
      • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
      • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
    4. Double click on combofix.exe & follow the prompts.
    5. When finished, it will produce a report for you.
    6. Please post the "C:\ComboFix.txt" along with a new HijackThis log for further review.
    **Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

    Make sure, you re-enable your security programs, when you're done with Combofix.

    DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!


    Download HijackThis:
    http://www.trendsecure.com/portal/en-US/tools/security_tools/hijackthis/download
    by clicking on Download HijackThis Installer
    Install, and run it.
    Post HijackTHis log.
    Do NOT attempt to fix anything!

    NOTE. If you're using Vista, right click on HijackThis, and click Run as Administrator
