Unable to get rid of malware - Constant Avast alert pop-up

[partisana]

Hello,
3 days ago my PC got infected with  sirefef.y / sirefef.b
After serveral rounds of cleaning tools (CCCleaner, Spybot and Malwarebytes included), there's still something wrong, as I still constantly get an Avast pop-up alerting me about malware detected. (Besides that, my Windows firewall and Windows Update have dissapeard. I have installed Comodo firewall instead). However, I have just run a new Malwarebytes report and the result is clean. A quick Avast check also says there is nothing wrong. But the truth is the Virus Vault is packed with this malicious thing and I have no clue on what to do. I delete it and it grows back again!
I am attaching the OTL and the aswMBR.exe files.
Hope you can help me.
thxs in advance

yes he does

Hello,
I have followed your instructions and, voila!, everything seems back to normal =) No Avast pop-ups yet ant the Virus Valut remains clean after some minutes using the net.
I am attaching the 2 resulting logs.
My Windows Firewall has also been restored. I am wondering... what should I do now? Keep Comodo and MS activated? Isn't it a bit too much?
Windows Update also seems to be back on track.
Let me know if there is anything else I need to do.
Really appreciate your help with this mess.
cheers

OK here is a lot more there that needs to be removed I will try first with combofix, but that may fail..  Do you have your windows CD so that we can use the recovery console ?

1. Close any open browsers.
2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
3. Open notepad and copy/paste the text in the quotebox below into it:

File::
c:\windows\system32\services.exe.59F5210B992624CB
c:\windows\system32\services.exe.8C107346C3B3529F
c:\windows\system32\services.exe.71BEAB5DE7312F27
c:\windows\system32\services.exe.E727CF79D2EBDE0D
c:\windows\system32\services.exe.135C9548117C4245
c:\windows\system32\services.exe.688F49408E9C7DC1
c:\windows\system32\services.exe.3CDF21FB3BB11987
c:\windows\system32\drivers\rsbhagvf.sys

Folder::
C:\Windows\Installer\{0e7e658c-01b8-b404-ce34-0bed7c780ec3}
C:\Users\susan\AppData\Local\{0e7e658c-01b8-b404-ce34-0bed7c780ec3}

Driver::
rsbhagvf

Save this as CFScript.txt, in the same location as ComboFix.exe


Refering to the picture above, drag CFScript into ComboFix.exeWhen finished, it shall produce a log for you at C:\ComboFix.txt which I will require 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.

Hello,
umm. I'm afraid I haven't got the Windows recovery CD...
what's the risk of following these instructions without it?
thxs

[essexboy]

No risk, it is just that if this fails as I feel it may we will need to work outside of windows..

So next question then is are you able to burn a CD or do you have a USB drive of at least 4Gb that we can use for data transfer.  (everything on the USB will be wiped so remove any files you want to keep first )

[partisana]

Hi there,
thanks for your patience here
The only Windows CD I have is the Upgrade to 7 HP sent me. I guess this is not what you're asking for, ain't it?
regarding 4gb usb... nope.. I have a DVD-R, if it's ok.
I know this question might sound stupid, but... if you know it is going to fail, why take the risk? What is exactly we have to remove know from the PC? Asking because it seems to work fine since the magic we did yesterday. Avast is calm, with no more alarming pop-ups or trojans in the vault. And Malwarebytes also is clean.
As you may figure out, I am just a plain Pc user. Changing anything in this thing makes me sweat! jaja

This is a new variant that we found the other day...  It will sit quiescent for a while and then jump back up again

I am not 100% sure that it will fail but there is always that possibility. 

If I have detected and included all the drivers in the fix then it will die, but if one is hidden it will regenerate

The combofix log will show me if it worked

[partisana]

glups.
gotcha
so there we go then... what should I do with the DVD-R? make some sort of backup copy?

[essexboy]

No we will just use that to create a windows recovery console if needed, that will then allow us to work outside of windows 

[partisana]

Hello,
I have just finished running the Combofix. I am attaching the report. Let me know if you see anything wrong.
cheers

[essexboy]

OK that seemed to work  There must only have been one driver

How is the computer behaving now ?
