Trojan.Sirefef and others (OTL, MBAM, aswMBR files attached) -- thx for yr help

Viruses and worms
1

Hi,

A couple of days ago, my wife inadvertently clicked on an Adobe-looking software update and gave access to the damned Sirefef and a bunch of other trojans. I have run Avast boot scan and MBAM in normal and safe mode, and each time it finds and quarantines things. I have disconnected my WiFi card so no Internet connection but when the Internet is on, Avast keeps warning about win32:Sirefef-PL and another trojan whose name I can’t remember. Unlike some other users, thankfully I have not been redirected to other websites but my turning off the WiFi card may have something to do with that. :slight_smile:

Anyway, I have followed the instructions on the forum and am attaching OTL.txt, aswMBR.txt and the MBAM log. All .txt files were saved in ANSI format. By the way, OTL did not produce an Extra.txt file.

I want to thank you in advance for helping me.

Best,
Afoyfs

Essexboy,

Thanks for the prompt response. I have one question before I run the fix. I have kept the infected PC offline so the virus does not make it worse. But one of the instructions on the OTL fix appear to update Java plug-in from Sun’s website, which would mean that I need to be connected to the Internet when running the OTL fix. Is this correct, or can I run the OTL fix while disconnected from the Internet?

Thanks,
Farhan

No that is the removal of an old an risky java active X

So run them all whilst offline ;D

Essexboy,

I ran the OTL fix and ComboFix. I am attaching two files that were created by OTL and the ComboFix log.

A couple of unexpected things happened during this clean-up process:
– I could not find the Avast shields control item in the system tray so I stopped Avast and also disabled VRDB generation. I think ComboFix worked fine but wanted to tell you about this as I am not sure if Avast was properly shut down.
– During ComboFix, two dialog boxes opened up for pev.3XE and PEV.exe, each saying that this program “has stopped working. A problem has caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.”

I don’t know if these issues had any impact on the fix. My PC seems to be working fine. It booted in decent time and I am on the Internet and Avast is running but it hasn’t caught any viruses. Hopefully the OTL and ComboFix logs can tell you if the trojans are gone. I will report back at the end of the day and let you know how the PC is doing.

Thanks,
Afoyfs

Are you still running Avast 4 ?

7

Yes, 4.8

8

Any specific reason as to why you have not updated to version 7 ?

How is the system behaving now ?

9

No reason, just laziness :frowning:

I just installed Avast 7 and am running the boot scan. It has found more instances of win32:Sirefef-PL [RTK], win32:Malware-gen and INI:cycbot-gen, so I guess the virus was either not cleaned completely or it has returned. sigh!! The PC ran fine all day yesterday but today my wife said another Adobe upgrade message popped up similar to what preceded the first infection. I have not seen this myself so I can’t describe it to you.

I told Avast to delete the infections and will attach the Avast log file when the boot scan is complete.

Please advise on what I should do next.

Thanks,
Afoyfs

P.S. What did the messages related to pev.3XE and PEV.exe mean from the previous clean-up?

10

Essexboy,

Here are the logs from MBAM, OTL and aswMBR. I said I would provide a log from Avast but I couldn’t see where the logs are maintained in the new setup for Avast 7. Anyway, looks like we are back to the beginning of troubleshooting the God-awful trojans and you want to see the MBAM, OTL and aswMBR logs anyways…

Thanks,
Afoyfs

It looks as though it failed to install this time… A suggestion if I may rather than let programmes auto update do it yourself. When I clean up there will be a small programme to assist in this

THEN

Run Combofix once more and allow it to update if requested. Then attach that log

Once done could you let me know how the computer is behaving

The Avast boot log is here C:\ProgramData\AVAST Software\Avast\report\aswBoot.txt

12

Essexboy,

Sorry but I am not sure what failed to install this time.

Afoyfs

13

The malware from the adobe popup ;D

14

Oh, I see. That’s great.

I agree with you on updating myself rather than letting programs do it automatically. The only program I allow to update automatically is Avast but clearly Adobe is having a party at my expense and Java also keeps prompting me to update. In answer to your question, yes, I will update programs manually.

I will run this fix later this evening when I get home, post the logs and then monitor the system for a day or two and let you know how it’s running.

Thanks again,
Afoyfs

15

I never let anything auto update bar windows and Avast. I will give a link to the programme that I use monthly to check my programme updates when I remove the tools and tidy up

Essexboy,

OTL fix ran fine but while running Quick Scan, the computer crashed. Could it have something to do with me selecting All Users for the Quick Scan? That doesn’t make sense to me but thought I’d mention. After rebooting, I re-ran OTL Quick Scan and it ran fine. Then I ran ComboFix and it ran fine too.

I am attaching all the relevant logs: the output of OTL Run Fix (07182012_224451.log), the output of the successful OTL Quick Scan (OTL_07182012.Txt), the output of ComboFix (CombFix_07172012.txt), and the message I received when the PC rebooted after the crash (Crash.txt).

Two weird things are happening: (1) three icons have appeared on my desktop after the OTL Quick Scan: Desktop.ini twice and a Word document named ~SCIALS1.docx. (2) When I try to open C:\ComboFix.txt, I get a system message saying an “illegal operation attempted on a registry key that has been marked for deletion.”

Given the crash and the suspect icons, I am doubtful that my system is clean. Any help would be much appreciated. I will use the PC as normal (Internet connection included) and let you know how it goes.

Thanks,
Afoyfs

Ref the illegal operation

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.

Sometimes malware does fight back and crash the system, but it is not a major problem if it only occurs once
The icons are system files and will be rehidden once we finish

After this run can you let me know what problems remain

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

Be advised that when the fix commences it will shut down all running processes and you may lose the desktop and icons, they will return on reboot

Run OTL

Both the OTL Fix and Quick Scan ran perfectly and I am attaching the log from both here.

The PC has been running fine over the past day.

Thanks,
Afoyfs

Subject to no further problems :slight_smile:

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so…The following will implement some cleanup procedures as well as reset System Restore points:

Run OTL
[*]Under the Custom Scans/Fixes box at the bottom, paste in the following

:Commands [resethosts] [emptytemp] [Reboot]

[*]Then click the Run Fix button at the top
[*]Let the program run unhindered, reboot the PC when it is done

Remove ComboFix

[*]Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
[*]In the Run box, type in ComboFix /Uninstall (Notice the space between the “x” and “/”) then click OK

http://i1224.photobucket.com/albums/ee362/Essexboy3/Misc%20screen%20shots/CF_Uninstall-1.jpg

[]Follow the prompts on the screen
[]A message should appear confirming that ComboFix was uninstalled

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

We will now confirm that your hidden files are set to that, as some of the tools I use will change that

[*]Go to control panel
[*]Select folder options (Appearance > Folder options in category view)
[*]Select the View Tab.
[*]Under the Hidden files and folders heading select Do not show hidden files and folders.
[]Click Yes to confirm.
[]Click OK.
