I have a two fold problem. First is a blue screen problem on reboot. Windows will load, get the music and my desktop complete with icons. The hour glass will appear and my icons will blink. Then after about 30 seconds, the Task Bar will turn white, my icons will blink and then I get a blue screen:

Stop: C000021a {Fatal System Error}
the windows login process system process terminated unexpectedly with a status of 0xc0000005 (0x0000000 0x0000000) The system has been shutdown.

If I reboot in Safe Mode and chose Safe Boot with last known good configuration, Windows will load, but that is the only way it will load.

Now for the second problem, I have a Trojan. When I click on links in my browser I am being redirected to various sites or I get a Shield saying I might get a virus (that one is new today) I run a Host file so the site, yesterday it said Podmena.in, is being blocked by the Hosts file. I have turned off the Host file and it makes no difference. I have run Malwarebytes repeatedly and the Trojan still comes back. I am wondering if rebooting with the good configuration is causing it. Here are the steps I have done, some many times

Operating System Windows XP service pack 2
WinPatrol loads on Start Up as well as AVG Free
Using Mozilla Firefox 3.6.8 (although I get the same results with IE)

Ran ChkDsk
Ran Registry First Aid
Turned Off System Restore
Ran Malwarebytes Full Scan

Here are the last 2 logs:

When this was done, I rebooted, got the blue screen mentioned above so booted with Safe Mode/Good configuration and windows loaded. For the first time, I was able to click on some sites but after a few minutes, I began having the same trouble. I am not visiting any malicious sites, just my blog and a Yahoo group. So I ran Malwarebytes again, and sure enough, the files are back

Hello ,I am moving this from XP to the Am I Infected forum.



Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.



Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.
Please ask any needed questions,post logs and Let us know how the PC is running now.
How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook

Ok, following your instructions, I downloaded ATF Cleaner and updated my SUPERAntiSpyware and corrected the Scanner Options

From Safe Mode, I login in as my User, Sandy and ran ATF Cleaner per your instructions. I do use Firefox so I followed those steps as well

Next I ran a Scan with SUPER, here is the resulting log:

Ok, we have some serious registry corruption from these malwares. Other than a format and re install we will need to do a one on one fix with special tools. I do not want to lose the machine.
Please go here....
Preparation Guide ,do steps.

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
I recommend you skip the GMER step for now.

Let me know if that went well.

Thanks for all your help. I followed the steps and created a DDS file and have opened a Topic on the forum you directed me to. I am hoping we can get this resolved, I really don't want to wipe the hard drive and start over, especially since I don't have service pack 2 for XP only the basic load. I may just be pushed into getting a MAC and using my laptop for my graphics programs.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/340499/blue-screen-and-browser-trojan/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
