Hi,
I already posted here:
http://www.bleepingcomputer.com/forums/ind...mp;#entry857819
and I did a checkdisk and it repaired some problems.

I am very convinced I have a trojan and/or viruses. One of them is the winlogan.exe and also nn

Upon bootup I get the error
Error loading c:\winnt\system32\fdhognsa.dll

Plus netsh.exe keeps popping up in a command window.

When I try to do anything the desktop disappears and then reappears. I have some functionality.
I tried to do an online scan and it found threats but IE crashed before they were fixed (tried it twice).

I have downloaded a bunch of antispyware/malware programs with my other PC and will try to run them on my infected desktop.
I've been working on this all day and getting nowhere fast. I did delete a bunch of crazy .exe files that were in the root directory and put there yesterday--many of which were identified as malware in this site.

If anyone has additional advice, please let me know. THis is crazy and I really have some important work I need to get finished on this computer.
Thanks.

Now the desktop just keeps blinking. If I look in the task manager it shows explorer.exe running, then disappearing, then running, as the desktop blinks on and off.
I'm going to boot up in safe mode and try to run the antimalware.
I want to get a reference hijack log.......

Well, I'm having a conversation with myself! I managed to copy all the antispyware installers onto my hard drive using the command window. But I can't get any to load. My CPU usage is stuck at 100% and I don't know which process is doing it. Maybe that's why the programs won't install? It looks like hijack this installed, and there is a desktop icon, but it won't run. I've been at this ALL DAY and I could just about throw up by now.
Please, if anyone has any ideas and some spare time, I'd love some help.
Thanks in advance.

I tried to install ad-aware to no avail.
Avira seemed to be installing but now I got the error message :The file could not be copied. Error code:2 c:\docume~1\admini~1\locals~1\temp\rarSFX0\basic\ADDR_FILE.HTML

I am trying to install these programs in Safe Mode and hoping one of them actually installs and runs.

OK, in safe mode I ran Ccleaner and ATF cleaner. Then Macafee Stinger, which found nothing.
I have booted up in regular mode and am installing bitdefender. In the meantime, I still got the message Error loading c:\winnt\system32\fdhognsa.dll, and csrssc.exe is trying to access the internet, stopped by ZoneAlarm.....

BItdefender found a trojan and found nnrun.exe. However, when I restarted I got the same problems AGAIN.

BItdefender found a trojan and found nnrun.exe

Where is it located (full file path) on your system.

Try redownloading and running MBAM again. It was updated yesterday and they were supposed to fix the BSOD problem when scanning. Follow the below instructions.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on Download_mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Acan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad and you may be prompted to restart your computer. (see Note below)
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Instructions with screenshots if needed.

Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

Upon bootup I get the error
Error loading c:\winnt\system32\fdhognsa.dll

It's not unusual to receive such an error after using tools to remove malware infection.

A "Cannot find...", "Could not run...", "Error loading... or "specific module could not be found" message is usually related to malware that was set to run at startup but has been deleted. Windows is trying to load this file but cannot locate it since the file was mostly likely removed during an anti-virus or anti-malware scan. However, an associated orphaned registry entry remains and is telling Windows to load the file when you boot up. Since the file no longer exists, Windows will display an error message. You need to remove this registry entry so Windows stops searching for the file when it loads.

To resolve this, download Autoruns, search for the related entry and then delete it.
  • Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if you're not sure how to do this.)
  • Open the folder and double-click on autoruns.exe to launch it.
  • Please be patient as it scans and populates the entries.
  • When done scanning, it will say Ready at the bottom.
  • Scroll through the list and look for a startup entry related to the file(s) in the error message.
  • Right-click on the entry and choose delete.
  • Reboot your computer and see if the startup error returns.
