Having trouble removing this infection win32:sirefef-AO [Rtk]

I need a bit of help removing this virus. Avast recognizes the attack but does not remove it or resolve the problem in any way. The alert just keeps popping up over and over and over… Step by step instructions to remove it would be very very very very helpful. I listed the info I have below and hopefully the link to the screen shot i took of avast scan results works. I need to have this removed asap! Thanks guys!!!

Alert 1
Object c:\Windows\Installer{1e2d99a3-5641-576c-4540-0f…\800000cb.@
infection: Win32:Sirefef-AO [Rtk]

How do i attach rather than copy and paste into this post?

sorry i found it

this is from the second run of otl.

If you have no objection I would like to try this fix a different way as one of my tools has been updated to combat this and I would like to see how it performs

[*] Download RogueKiller and save it on your desktop.
[*]Quit all programs
[*] Start RogueKiller.exe.
[*] Wait until Prescan has finished …
[*] Click on Scan

Please post: All RKreport.txt text files located on your desktop.

THEN

Download AdwCleaner from here to your desktop
Run AdwCleaner and select Delete

https://dl.dropbox.com/u/73555776/AdwCleaner.GIF

Once done it will ask to reboot, allow this
On reboot a log will be produced please attach that

I have walked through all the provided steps. I am waiting now to see if the alert pops up again. Thank you for your help again.

Could you attach the rogue killer logs please

My apologies. I thought i uploaded it.

Not bad it wiped the ALSR but was unable to replace services.exe … So lets do that now

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

http://img.photobucket.com/albums/v706/ried7/NSIS_extraction.png

[*]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

THEN

run farbar service scanner

https://dl.dropbox.com/u/73555776/FSS.GIF

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.

https://dl.dropbox.com/u/73555776/bits_vista.reg
Double click the reg file and allow to merge
Reboot and let me know what problems remain

So far everything seems cool. Thank you again. :slight_smile:

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.

SPRING CLEAN

To manually create a new Restore Point

[*]Go to Control Panel and select System
[*]Select System
[*]On the left select System Protection and accept the warning if you get one
[*]Select System Protection Tab
[*]Select Create at the bottom
[*]Type in a name i.e. Clean
[*]Select Create

Now we can purge the infected ones

[*]GoStart > All programs > Accessories > system tools
[*]Right click Disc cleanup and select run as administrator
[*]Select Your main drive and accept the warning if you get one
[*]For a few moments the system will make some calculations
[*]Select the More Options tab
[*]In the System Restore and Shadow Backups select Clean up
[*]Select Delete on the pop up
[]Select OK
[
]Select Delete

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

http://img233.imageshack.us/img233/7729/mbamicontw5.gif

Malwarebytes. Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit

[*]Microsoft Windows Update
