Title: Caught a Virus that avast block call assembly\temp\U\80000032.s
Post by: Valkreze on January 04, 2012, 02:31:06 PM
Hi, recently caught a virus that redirect me to other sites, and then I download Avast and MBAM. Avast been keep popping up and block a virus name 80000032.s that is targeting my SVChost.exe file. On MBAM I did a full scan and found a file name KWRD.DLL and MBAM had removed. But 80000032.s is still affecting my computer.

I further hope you guys can assist me to battle this virus so I can happily use this laptop again.

This needs further analysis by a malware removal specialist:
Go to this topic http://forum.avast.com/index.php?topic=53253.0 (http://forum.avast.com/index.php?topic=53253.0) for information on Logs to assist in cleaning malware. Use the information about getting and using the logs and attach the logs here, not in the LOGS topic.

I thought I have uploaded a Log, isn't the OTL is what you are looking for? Oh I got what you mean, thank you.

That isn't all of them, there should also be extras.txt when you first run OTL and there are other analysis tools in that topic.

It won't be me looking at them (I'm not a malware removal specialist), I just preparing the ground, so that when one is able to help they have all the information.

The infection is actually is typical to a file infector...so it needs a bootable rescue disk..i suggest <snip> in this case since it has great disinfection capabilities....

You have previously been warned about offering malware removal advice and this has now been reported.

Hi 'tis a variant on the zero access rootkit.  First could you confirm that system restore is operative

Then 

Download and Install Combofix
 
Download ComboFix from one of the following locations:
Link 1  (http://download.bleepingcomputer.com/sUBs/ComboFix.exe)
Link 2 (http://www.forospyware.com/sUBs/ComboFix.exe)
 
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  (http://forums.whatthetech.com/How_Disable_your_Security_Programs_t96260.html&pid=494216#entry494216)

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

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

'First could you confirm that system restore is operative"

How do I confirm that?

Here is the combo fix log

In Win7, Control Panel, System, System Protection, System Restore, Protection Settings.

I have it but don't know if it is working. But it should be working.
Title: Re: Caught a Virus that avast block call assembly\temp\U\80000032.s
Post by: DavidR on January 06, 2012, 03:08:21 PM
Well the screen should show you if it is On or Off on your various drives. If you click the System Restore button another window should open and you should be able to delve deeper and see your restore points.

I can't be much practical help as I disabled system restore on my systems (more years ago than I can remember), replacing it with drive imaging software.

Hi the reason I asked for that is that some of these variants are badly constructed and wreck the network connections

But having said that - what are your current problems

Subject to no further problems   :)

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.
Remove ComboFix
.
.
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
.

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:
.
SPRING CLEAN
.
To manually create a new Restore Point
 .
Now we can purge the infected ones
.
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 (http://www.malwarebytes.org/mbam-download.php).  Update and run weekly to keep your system clean
.
Download and install FileHippo update checker (http://www.filehippo.com/updatechecker/) 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
.
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 ? (http://www.geekstogo.com/forum/topic/225044-preventing-malware-and-safe-computing/)

Keep safe  :wave:
