I recently found that my pc is infected with the subject trojan. I am reimaging my drive but was wondering how I may have come across the virus. I have been to no website that I do not normally visit. The only thing I can think may have happened is that it could have either come from my iphone or my flash drive. I recently took my flash drive to Walgreens to have some pictures printed on their kiosk, is it possible that the trojan could have gotten onto my flash drive when I did this? Or maybe have gotten on my phone?

Thanks,

Hi and welcome to GeeksToGo! Please make sure you read all of the instructions and fixes thoroughly before continuing with them. If you have any queries or you are unsure about anything, just say and I'll help you out :)

It may well be worth you printing/saving the instructions throughout the fix, so you have them to hand just in case you are unable to access this site.

Please note:
  • Remember to post your logs, not attach them. So, any logs from any programs we run, should be just 'copied & pasted' into your reply.
  • Please only run the tools that I request. I know malware can be frustrating but running other tools in the meantime and between posts, only makes it harder for us to analyse and fix your PC in the long run.
  • Please subscribe to this topic if you have not already done so. Please check back just in case, as the email system can fail at times.
  • Just because your machine is running better does not mean it is completely cleaned. Please wait for the 'all clear' from me to say when we are done.
  • Please reply within 3 days to be fair to other people asking for help.
  • Please tell me if you have your original Windows CD/DVD available
  • When in doubt, please stop and ask first. There's no harm in asking questions!

Please follow the steps bellow:

Step 1

  • Please download aswMBR.exe to your desktop.
  • Double click the aswMBR.exe to run it.

  • When asked if you want to download Avast's virus definitions please select Yes.
    Note: If avast! antivirus is already installed, just do the next step.
  • Click the Scan button to start scan.

    Posted Image
  • On completion of the scan click Save log, save it to your desktop and post in your next reply.
  • Also on Desktop there should be a file called MBR.dat after that. Please attach it here.

Step 2

Posted Image OTL Custom Scan

  • Download OTL to your desktop.
  • Double click on the Posted Image icon to run it.
  • Make sure all other windows are closed and to let it run uninterrupted.
  • When the window appears, underneath Output at the top, make sure Stadard output is selected.
  • Select Scan all users
  • Under the Extra Registry section, check Use SafeList
  • Check the boxes beside LOP Check and Purity Check.
  • Under the Custom Scans/Fixes box copy and paste this in:

    netsvcs
    %SYSTEMDRIVE%\*.exe
    %systemdrive%\$Recycle.Bin|@;true;true;true
    /md5start
    services.*
    explorer.exe
    winlogon.exe
    userinit.exe
    svchost.exe
    consrv.dll
    /md5stop
    HKEY_CURRENT_USER\Software\Microsoft\Windows Media\WMSDK\Local\AutoProxyCache /s
    %systemroot%\*. /mp /s
    %Temp%\smtmp\*.* /s
    hklm\software\clients\startmenuinternet|command /rs
    hklm\software\clients\startmenuinternet|command /64 /rs
    CREATERESTOREPOINT
  • Click the Posted Image button. Do not change any settings unless otherwise told to do so. The scan wont take long.
  • When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
  • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time and post them in your topic
