Title: My school computer is screwing up please help
Post by: lzeppelinrocks on December 06, 2010, 02:07:03 AM
I got a virus called antimal software a week ago and my computer hasnt been the same since. The instruction at "0x7c923845" referenced memory at "0x00000000". The memory could not be "read".
Click on OK to terminate the program
Click on CANCEL to debug the program
I keep getting this error everytime i start my computer up or switch users. My computer freezes up about once every 2 hours, and i have to manually shut my computer down. i have run mbam, avast, symantec, all the virus scans countless times and cant find anything else. Please help, I think what is wrong is my system files are ****** up but i dont have my computers disc to run the sytem file repair program. My internet also freezes about every half an hour and my computer has to be manually shit down. Also, my wireless sometimes disconnects randomly and says the wireless has been configured to not connect here or something and the wireless does not connect.

If you have a 32-bit OS, you can try a boot time scan with Avast.

Do you have both Avast and Symantec on your machine?  You cannot have more than one resident antivirus running on your machine at the same time or it will cause conflicts.  If you do have both, here is the uninstaller for Symantec: http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20080710133834EN (http://us.norton.com/support/kb/web_view.jsp?wv_type=public_web&docurl=20080710133834EN)...then reboot.

Reset the router to its default configuration.  This can be done by inserting something tiny like a paper clip end or pencil tip into a small hole labeled "reset" located on the back of the router.  Press and hold down the small button inside until the lights on the front of the router blink off and then on again (usually about 10 seconds).

Check the information on the first post of this thread under Virus/Worms for you to check your machine for malware: http://forum.avast.com/index.php?topic=53253.0 (http://forum.avast.com/index.php?topic=53253.0). 

Follow the directions for obtaining the OTL logs (save them as ANSI and not Unicode).  Post the MBAM log here and the two (2) OTL log as an attachment (Additional Options > Attach > Browse (the logs will be on your desktop > Post).  We will review your logs and refer to our Certified Malware Expert (Essexboy) if needed. 

***Please do not make any further changes to your machine after you have provided the logs.***

Let me know if you have any additional questions.  Thank you.

I ran avast last night just to check for the last time, because i had run avast, mbam, and symantec a few hours before and avast found around 60,000 infected files, all in the symantec foler named "xfer". WTF! I couldnt actually do anything to any of the files because it said it could not found the file specified. My computer isnt really showing any signs of malware though, and around half of the day it works totally fine and runs smoothly. But, at a random time the "The instruction at "0x7c923845" referenced memory at "0x00000000". The memory could not be "read".
Click on OK to terminate the program
Click on CANCEL to debug the program"
message comes up, and basically my computer just starts fucking up. The wireless doesnt work, my computer constantly freezes and i have to do a hard shutdown, programs take sometimes over 5 minutes to start to run. Only after that message comes up. So i am thinking whatever that instruction is, is the problem.
Also, this is my school computer and i cant uninstall symantec, so i guess ill have to uninstall avast.

Does this machine belong to the school or you?  If it belongs to the school and they put symantec on it, then you have no choice but to uninstall avast since you cannot have more than one AV on your machine.  If it belongs to you, you can uninstall symantec.

You are getting the error codes because of the 2 AV's and/or the malware and the combination of the two.

I already gave you the symantec uninstaller tool.  Here is the Avast Unintaller Tool if you need it:
1. Download the Avast Uninstall Utility, aswClear5.exe http://www.avast.com/uninstall-utility (http://www.avast.com/uninstall-utility) and save it to your desktop.
2. Disconnect from the Internet at this time.
3. Go to Control Panel and uninstall Avast through Add/Remove Programs if possible and reboot.
4. If Step 4 fails, boot into Safe Mode (http://Safe Mode) (hit F8 repeatedly) and run the Avast Uninstall Tool.
5. Reboot.

Let me know if you have any additional questions.  Thank you.

Alright im pretty sure i have some type of virus. I uninstalled avast, and literally nothing changed about my computer. That svchost.exe message still comes up and my computer still goes to shit when i exit out of it. Do i click debug or terminate the process though? I usually debug it but to be honest have no idea what that means. Idk what to do, i have run avast, symantec, and mbam several hundred thousand times and nothing changes. I think i got the virus on my dsadmin though, becuz if i try to log onto my dsadmin, well i cant. All that loads to my dsadmin is the desktop picture no taskbar, no icons, you can do ctrl - alt - del but that does nothing. Am i just like screwed and have to pay 2,500 dollars for a new school computer?

Have you tried updating and running MBAM in Safe Mode? 

What AV do you currently have on your machine now?

Please answer the above questions and do not make any further changes to your machine and I will have a Certified Malware Expert, named Essexboy, try to help you.  He is on UK time zone and comes to the forum late UK time.  Check this thread daily and he will give you instructions on what to do.  Only take instructions from him or an Evang. at this time.  Do you have any questions?

Hello everyone. I just wanted to thank everyone for replying first off. Essexboy, i would do what you aid i should but my computer cant connect to the internet anymore... There is no wireless thing in the taskbar anymore. There is nothing in the network connections folder and even if you plug the computer directly into a router or something it will not connect. Also half the time i log onto my computer, just the desktop loads and ther is no taskbar or desktop icons so the only way you can do anything is to do ctrl alt del and start a new task. My whole life centers around this piece of shit computer and this sucks s much. I will do exactly what you said to do essexboy once, and if i am able to connect to the internet.

See if you can get a friend to download them for you, copy to a CD, safer than a USB and copy them to your system.
Title: Re: My school computer is screwing up please help
Post by: lzeppelinrocks on December 13, 2010, 03:35:23 AM
i will try that, but does anyone know how to get my internet to work? and also my taskbar and windows just looks weird... Like i usually had a black taskbar and black bar things on the top of browsers, but all of a sudden they all turned white and look like windows classic. Also, it usually took about 5 minutes to log on now it takes like half a second. This all started happening today and i had not used my computer in a day or two.
Title: Re: My school computer is screwing up please help
Post by: DavidR on December 13, 2010, 04:34:45 AM
Before you can get that to work or attempt to get it to work you need to clean your system as the malware an be hooking your connection. Removal of the malware could inadvertently take that down, so you could be fighting that battle many times over.

So essexboy is the one to help with that and to do so he needs the logs.

Unfortunately he is in the UK, like I am and he works, so will be in bed now as it is a little after 3.30am in the UK right now.

My wireless randomly started working and i ran the scan that essexboy said to run. Do you guys want the logs? Is my computer fixed now? What did that scan do? Sorry if i seem a little bit weird but i have an essay due... and this is not good.

Title: Re: My school computer is screwing up please help
Post by: SafeSurf on December 13, 2010, 10:09:32 AM
Yes, we will need the logs.  Make sure the OTL logs are saved as ANSI and not Unicode.  Post two (2) OTL log as an attachment (Additional Options > Attach > Browse (the logs will be on your desktop > Post).  Thank you.

The scans are a diagnostic tool that will give us information as to what might be causing your problems.  We can't tell you if your machine is fixed now or not until we review your logs.

***Please do not make any further changes to your machine now that you have provided the logs.***

Let me know if you have any questions.  Thank you.

Hey, I ran OTL again and did what you said and here is the log. There was other log that came up and idk what it is so ill post that too. But combofix didnt work. I would start it and everything and then randomly a message that says CFscript is spelled wrong and that i should check the spelling. Then i click ok on that message  and combofix closes. Also, there is no possible i can turn off symantec antivirus because its the school virus scan or something. And it said Avast was still running and im pretty sure i uninstalled it.

Could you try Combofix again please, just double click the icon

Alright i tried Combofix 4 more times, none of them working. Also, whenever my computer starts messing up it randomly tuns to windows classic style bars.. it wont let me change it when  it does that too. Not a big deal i just dont know if that cld be something

I'm jumping into this topic because I'm having the same problem... ("Svchost.exe Application Error" The instruction at "0x7c923845" etc.). No matter what you do when this pops up, your computer freezes and you're forced to reboot to get it going again.  The only reason I'm on here now is because I didn't choose either of the options (ok to terminate OR cancel to debug), I simply dragged the error down to the bottom of my screen for now...

I do know this.  Whatever caused this began when I clicked on a link to play hidden objects 4, on Facebook...  I knew immediately that it was not a good link because my computer (or the link) started a malware scan. (I turned my computer off in the middle of the chaos and the scan never completed). I noticed a couple files that seemed suspicious in my WINNT\TEMP and deleted them (4225859.exe and another file with a different extension).  I also disabled this in msconfig's startup... (not sure if I should have done any of that, but since I couldn't determine what 4225859.exe was, I took my chances and deleted it)...

I used your OTL and scanned as you directed.  The two .txt files are on my desktop, but I didnt have the program make any changes because I just wasn't sure what would happen there... If you give me the ok, I'll post the results here.  (I figured out how to attach them and here they are.

Thanks so much,


ICAngels

Post by: ICAngels on December 29, 2010, 05:33:21 AM
Followed your instructions.  The svchost error came up just before I did the fix and my computer wouldn't reboot when the program tried to.  So, I manually shut it down and did the fix a second time.  I reinstalled the microsoft security, so you'll notice it in the new log I'm attaching.  

Before I did all this, I received an email from my bank's security dept notifying me that their rapport (spyware) caught & stopped 4 trojans when I accessed my account this morning... Ugh...  (TDL4 (severity: High);  Zeus 2 (severity: High); TDSS (severity: High); Hiloti (severity: High).  My Microsoft Security Antispyware scanned and only found two instances of Hiloti and deleted them.  It didn't seem to recognize the other three.  I also don't know if combofix took care of the other three viruses.  


Thank you so much for your help here...

**UPDATE:  No problems for a while then a new one is popping up now...
AXWINFRAME Windows: svchost.exe - Application Error (instruction at "0x16cda24e" referenced memory at "0x16cda24e" The memory could not be written...

12/29 - Ugh...  The original svchost.exe - Application Error just popped back up...

Combofix confirms the TDL4 infection so lets kill that now - Whilst you are doing this I will read the rest of the logs  ;D

Please read carefully and follow these steps.
