Hey,

a couple of days ago my antivirus spotted these two on my computer: trojan.sirefef.ty and trojan.generic
they keep returning and scanning the whole thing won't help, also they block my internet connection

Can anyone help me cleaing this up?

I have windows 7 running and my antivirus is bitdefender total security 2010 (license is still running)
I post this message fom another computer, but i can still enter safe mode with an internet connection if necessary

OK from safe mode with internet

Download OTL to your Desktop
  • Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.

  • Select All Users
  • Under the Custom Scan box paste this in
    netsvcs
    %SYSTEMDRIVE%\*.exe
    /md5start
    services.*
    explorer.exe
    winlogon.exe
    Userinit.exe
    svchost.exe
    /md5stop
    HKEY_CURRENT_USER\Software\Microsoft\Windows Media\WMSDK\Local\AutoProxyCache /s
    CREATERESTOREPOINT
  • Click the Quick Scan 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.
  • Post both logs

THEN

Download aswMBR.exe ( 4.8mb ) to your desktop.
Double click the aswMBR.exe to run it Click the "Scan" button to start scan

I did the scan with OTL, but I can't complete the scan with aswMBR. It starts scanning, it finds some infected files, but somewhere during the scan my computer shuts down or goes to blue screen.

OK lets go for it

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

    Posted Image

    :OTL

    [Reboot]

  • Then click the Run Fix button at the top
  • Let the program run unhindered, reboot the PC when it is done
  • Open OTL again and click the Quick Scan button. Post the log it produces in your next reply.

THEN

Download and Install Combofix

Download ComboFix from one of the following locations:
Link 1
Link 2

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here
  • Double click on ComboFix.exe & follow the prompts.
  • Accept the disclaimer and allow to update if it asks

    Posted Image
  • When finished, it shall produce a log for you.
  • Please include the C:\ComboFix.txt in your next reply.

Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.
3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.



Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

Was the infected file found in either OTL_moved files or Qoobox ?

When you try to connect to the internet what error do you get ?

run farbar service scanner

Posted Image

Tick "All" options.
Press "Scan".
It will create a log (FSS.txt) in the same directory the tool is run.

Please copy and paste the log to your reply.

you mean of the file that bitdefeder found?

I looked at logs and it appeared that there were again 2 infectedfiles(again sirefef.ty and generic)
the location is at C:\windows\assembly\GAC_32\desktop.ini (the other one is at GAC_64)

It is just the normal error: "conection timed out..."

OK lets reset the net connections etc.. Before we take a deeper look at the associated files and registry

Download Complete Internet Repair to your desktop

Unzip all the files to their own folder on the desktop
Within the folder double click CIntRep
The programme will then run
Select the items I have highlighted
Press go
Let me know if it is able to conduct the repair, there is a log under the file button
