Viruses and worms
1

Avast seems to have issues with WIN64/Sirefef/A, Win64/Sirefef/AO and WIN32/malware/gen. It says it has confined them to the chest but about every 3 minutes the warnings pop up again. I have looked at forums and seen many fixes that all involve having a good understanding of computer jargon. That is not me. I know how to point and click and follow directions, but all of that techie stuff seems WAY over my head. Can anyone PLEASE help me? Patience must be a virtue of yours.

siref is a nasty rootkit…so if detection is correct (usually is, has been many of these lately) you need Essexboy on this

follow this guide and attach (not copy and paste) logs from malwarebytes / OTL / aswMBR

I have the patience of a saint ;D

Essexboy…so far, you are my hero!
Hope I did everything right up to this point!

OK here we go… At any stage where you are unsure , just stop and ask

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

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

:OTL IE - HKLM\..\SearchScopes\{3d29c02b-bf3e-4d3b-8a7a-e0e7d0f6dbab}: "URL" = http://search.mywebsearch.com/mywebsearch/GGmain.jhtml?id=Z7xdm065YYus&ptnrS=Z7xdm065YYus&si=1579M&ptb=00D25E71-4124-4694-B311-F47CC4BCCCD4&psa=&ind=2012060518&st=sb&n=77ed9b66&searchfor={searchTerms} IE - HKU\S-1-5-21-1220945662-573735546-839522115-1003\..\URLSearchHook: {81017EA9-9AA8-4A6A-9734-7AF40E7D593F} - No CLSID value found IE - HKU\S-1-5-21-1220945662-573735546-839522115-1003\..\SearchScopes,DefaultScope = {70B3CC76-49D1-450A-9EB6-177561158AD6} IE - HKU\S-1-5-21-1220945662-573735546-839522115-1003\..\SearchScopes\{3d29c02b-bf3e-4d3b-8a7a-e0e7d0f6dbab}: "URL" = http://search.mywebsearch.com/mywebsearch/GGmain.jhtml?id=Z7xdm065YYus&ptnrS=Z7xdm065YYus&si=1579M&ptb=00D25E71-4124-4694-B311-F47CC4BCCCD4&psa=&ind=2012060518&st=sb&n=77ed9b66&searchfor={searchTerms} O2 - BHO: (no name) - {02478D38-C3F9-4efb-9B51-7695ECA05670} - No CLSID value found.

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.

[*]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

Scary! I pasted the fix and pushed the fix button. At first the icons disappeared and now the otl box is gone. All i am looking at is my screen saver. Is this what it is supposed to be doing?

7

read what Essexboy posted in red above :wink:

8

If the main OTL box has disappeared then reboot the computer please

9

It has been this way for about 45 minutes. Is that normal?

10

In that case reboot please and then proceed to combofix

11

Combofix stopped running. It said it couldn’t find a file and then froze on the screen.

12

OK could you delete that copy

Then press the globe under my avatar, that will take you to my skydrive. THERE you will find a file named Gotcha , download that to your desktop and run please

13

Whew…log attached ;D

14

Looks like this variant is changing, could you run a quick Avast scan now please… How is the computer behaving ?

15

So far, no more pop ups regarding sirefef or malware. I will run Avast now.

16

uh, I did mention the computer illiterate part, right? Variant changing means…?

17

Ah sorry, this malware changes the files used and how it affects the system very frequently. So each change is called a variant … As in Elgars variation on a theme ;D

The current one has been alive now for nearly two weeks so I guess it is due for a change

18

Thanks for the explanation! I actually get it…lol! Avast just finished running and found NO threats of any kind. Does that mean I am fixed?

19

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] [CLEARALLRESTOREPOINTS] [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
[*]Click Start.
[*]Open My Computer.
[*]Select the Tools menu and click Folder Options.
[*]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.

Your Java is out of date.
Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.

Upgrading Java:
[] Go to this site and click Do I have Java
[] It will check your current version and then offer to update to the latest version

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

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

To learn more about how to protect yourself while on the internet read our little guide How did I get infected in the first place ?Keep safe :wave:

I will do all of the clean-up. Just like a man to leave it for a woman…lol.

Seriously, you rock! You are the best! EVER! I REALLY appreciate your patience and your help! Hooray for being fixed! THANK YOU!!! Hugs!
