I am trying to remove viruses from a computer. I think I got some out but I am running into problems. The viruses won't allow Malwarebyte run...it comes on for 5 seconds then disappears. The same thing happens with hijackthis. I try it again and it says about the path being wrong. It won't let me take anything out of msconfig either. I know the permissions were changed. But anything I use to remove trojan viruses will not work. This includes Superantispyware, malwarebyte, hijackthis, combofix, I cant install Avast AntiVirus, nor will online antivirus software work, spybot search and destroy doesnt work. They don't work in the safe mode or the normal mode. I don't want to reformat the computer. It won't repair the operating system. Can anyone recommend anything? I'm stuck.
I'm sure the registry was corrupted as well. :angry:

Hello,is this an XP machine?

Reboot into Safe Mode with Networking
How to enter safe mode(XP/Vista)
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 with Networking using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.


>>>> Download this file and doubleclick on it to run it. Allow the information to be merged with the registry.

RKill....

Download and Run RKill
  • Please download RKill by Grinler from one of the 4 links below and save it to your desktop.

    Link 1
    Link 2
    Link 3
    Link 4

  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
  • Double-click on Rkill on your desktop to run it. (If you are using Windows Vista, please right-click on it and select Run As Administrator)
  • A black screen will appear and then disappear. Please do not worry, that is normal. This means that the tool has been successfully executed.
  • If nothing happens or if the tool does not run, please let me know in your next reply

Do not reboot your computer after running rkill as the malware programs will start again. Or if rebooting is required run it again.


If you continue having problems running rkill.com, you can download iExplore.exe or eXplorer.exe, which are renamed copies of rkill.com, and try them instead.



Next run Superantisypware (SAS):

Download and scan with SUPERAntiSpyware Free for Home Users
  • Double-click SUPERAntiSpyware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the Scanning Control tab.
  • 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.
  • Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan.
  • Click "Next" to start the scan. Please be patient while it scans your computer.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes".
  • 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.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.


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.

I have a question. I haven't tried to fix you were telling me about but I just wonder if these infections will return? Would it be better to reformat? I know that it might take more time, but it concerns me how infected this computer is.

Well I do not know yet if they are backdoors and/or rootkits,in which case i would want to reformat.

Your decision as to what action to take should be made by reading and asking yourself the questions presented in "When Should I Format, How Should I Reinstall?" In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore removes everything and is the safest action but I cannot make that decision for you.

Reformatting a hard disk deletes all data. If you decide to reformat, you can back up all your important documents, data files and photos. The safest practice is not to backup any autorun.ini or .exe files because they may be infected. Some types of malware may disguise itself by adding and hiding its extension to the existing extension of files so be sure you take a close look at the full name. After reformatting, as a precaution, make sure you scan these files with your anti-virus prior to copying them back to your hard drive.

I tried to run the file about the registry...copied file onto a flash drive and ran it on the infected laptop. It said it was sucessful. However when I ran hijackthis (for example), it says windows cannot access path or file. I reset the internet. Still nothing works. I'll keep trying.

nothing is working. First I tried to download the registry fix first. It said your current security setting do not allow this file to be downloaded. I reset the internet...that seemed to help. I tried rebooting and then opening hijackthis. It tells me that windows cannot access the path or file..

I do have the recovery disk for this laptop. Unless there is something else I can do, I might just have to reformat. Although I really want to leave this for the last resort.

I'll wait for any other suggestion.

What a pest! this one is LOL

Please download RSIT by random/random from the link provided for your operating system and save it to your desktop.
Link 1 for 32-bit version
Link 2 for 32-bit version

Link 1 for 64-bit version
Link 2 for 64-bit versionThis tool needs to run while the computer is connected to the Internet so it can download HijackThis if it is not located on your system. If you get a warning from your firewall or other security programs regarding RSIT attempting to contact the Internet, please allow the connection.

  • Close all applications and windows so that you have nothing open and are at your Desktop.
  • Double-click on RSIT.exe to start the program.
    If using Windows Vista, be sure to Run As Administrator.
  • Read the disclaimer and click Continue.
  • When the scan is complete, a text file named log.txt will automatically open in Notepad.
  • Another text file named info.txt will open minimized.
  • Save the log files to your desktop and copy/paste the contents of log.txt by highlighting everything and pressing Ctrl+C.
  • After highlighting, right-click, choose Copy and then paste the contents into a new topic in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here.
  • Copies of both log files are automatically saved in the C:\RSIT folder which the tool creates during the scan.
-- Note: Do not post the contents of info.txt in your reply. Instead, just include it as an attachment to upload using the "Browse" button in the text editor when making your reply.

Important: Be sure to mention that you tried to follow the Prep Guide but were unable to get DDS to run. If RSIT did not work, then reply back here.

Should I call it a day? :crazy:
