The network connections option is gone from the start menu and when i go and access it from control panel it says Svchost.exe Application error referenced memory could not be read. and wen it opens there is no lan connection and the lan is also not showing..... Broadband connection is also not showing, i cant excess internet also. sound is there but the wen i play movies or song there is no sound.
In safe mode with networking it shows the network connections but the DNS ip is blanc. i have run stinger.exe, nod32 but it doesnt show any virus or worm.

I didnt have much time on my hands so i formatted the c: drive and loaded original xp home edition sp2

But now the problem is that when i click on c: or d: drive it says cannot access have scanned the pc with nod 32 and deleted the autorun worm varients..... and the internet download speed has also decreased from 100kb/s to 2kb/s is there any relation with the virus....

Help required!!!

And i am currently using NOD 32 is it good enough or i need to go for anyother AV. If so than provide me a download linc

Thanks

No antimalware program protects/cleans your pc 100%. If I were you, I should try at least malwarebytes antimalware. Most likely this kind of problem is caused by some kind of malware.

From what you describe, it appears to be a USB flash drive infection. Flash (usb, pen, thumb, jump) drive infections usually involve malware that modifies and loads an autorun.inf (configuration) file into the root folder of all drives (internal, external, removable) along with a malicious executable. When the removable media is inserted (mounted), autorun looks for autorun.inf and automatically executes the malicious file to run silently on your computer. When a flash drive becomes infected, the Trojan will infect a system when the removable media is inserted if autorun has not been disabled. Read When is AUTORUN.INF really an AUTORUN.INF?.

The inability to open drives and partitions is a common signs of this infection.

Please insert your flash drive before we begin. Hold down the Shift key when inserting the drive until Windows detects it to bypass the autorun feature and keep autorun.inf from executing automatically.

Please download Flash_Disinfector by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.

Please download Malwarebytes Anti-Malware (v1.34) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on 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. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" 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.
  • 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with disinfection. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Temporarily disable such programs or permit them to allow the changes. Click this link to see a list of programs that should be disabled.

Some types of malware will disable MBAM and other security tools. If MBAM will not run, try renaming it.
  • Open the Malwarebytes' Anti-Malware folder in Program Files.
  • Right-click on the mbam.exe file, rename it to myscan and change the .exe extension to .scr, .com, .pif, or .bat.
  • Double-click on myscan.scr (or whatever extension you renamed it) to launch the program and perform your scan.

Please download sreng2.zip and save it to your Desktop.
  • Create a new folder on your hard drive called Sreng2 (C:\Sreng2) and extract (unzip) the file there. (click here if you're not sure how to do this. Vista users refer to this link.)
  • Open the folder and double-click on SREngLdr.EXE to launch it.
  • Select System Repair from the left pane.
  • Click on File Association.
  • Select all entries that have an 'Error status' and click Repair.
  • Exit SREng and reboot the computer.
If that does not work, please see Fix or Restore Broken .EXE .LNK .COM Association Caused by Virus or Broken EXE Association Fix.

The Svchost.exe Application error is likely a sign of a rootkit component which includes gaopdxserv.sys, gaopdx[random].dll and other malicious files.

Some infections are difficult to remove completely because of their morphing characteristics which allows the malware to regenerate itself. Sometimes there is another hidden piece of malware which has not been detected by your security tools that protects malicious files and registry keys (which have been detected) so they cannot be permanently deleted. Disinfection will probably require the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a DDS/HijackThis log for further investigation.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT Team members are very 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 "bump" your post or make another reply until it has been responded to by a member of the HJT 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 HJT Team member is already assisting you and not open the thread to respond.

Hello al's,

Now that you have a log posted here: http://www.bleepingcomputer.com/forums/t/211565/svchostexe-application-error-and-some-referenced-memory-could-not-be-read-mbamexe-not-running-after-installation-and-viruses/ 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 HJT Team member, nor should you continue to 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 HJT Team should be the only members that you take advice from, until they have verified your log as clean.

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.
