Sorry to bother you all again, but now I have the Rbot.gen trojan. I've just received it yesterday, and I really need to get rid of it quickly. All of my schoolwork and projects are on this computer, and so is all of my information. I already have SAS, MBAM, and ATFC. I use AVG Pro 8 as an antivirus, and so far it isn't ID'ing anything. Every time I start my computer, the Command Prompt always shows up running some script, and I close it. I just really need to get rid of this quickly!

Hello ,it's me again.Looks like it has gotten worse. Let me give you some important info about this IRC BOT infection.

IMPORTANT NOTE: Backdoor:Win32/Rbot.gen .... is a generic detection for a family of backdoor trojans that allows attackers to control infected computers.. backdoor Trojans, Botnets, and IRC Bots are very dangerous because they compromise system integrity by making changes that allow it to by used by the attacker for malicious purposes. Rootkits are used by Trojans to conceal its presence (hide from view) in order to prevent detection of an attacker's software and make removal more difficult. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. They can disable your anti-virus and security tools to prevent detection and removal. Remote attackers use backdoors as a means of accessing and taking control of a computer that bypasses security mechanisms. This type of exploit allows them to steal sensitive information like passwords, personal and financial data which is send back to the hacker. To learn more about these types of infections, you can refer to:

What danger is presented by rootkits?
Rootkits and how to combat them
r00tkit Analysis: What Is A Rootkit

If your computer was used for online banking, has credit card information or other sensitive data on it, you should disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised and change each password using a clean computer, not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
What Should I Do If I've Become A Victim Of Identity Theft?
Identity Theft Victims Guide - What to do


Although the infection has been identified and may be removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume the computer is secure even if the malware appears to have been removed. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired so you can never be sure that you have completely removed a rootkit. The malware may leave so many remnants behind that security tools cannot find them. Tools that claim to be able to remove rootkits cannot guarantee that all traces of it will be removed. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:

When should I re-format? How should I reinstall?
Help: I Got Hacked. Now What Do I Do?
Where to draw the line? When to recommend a format and reinstall?


Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful. 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. Let me know how you wish to proceed.

Reformating is something I just cannot do. I have all of my stuff on here, so I'll have to go with removing it with the tools. Ugh, this is having me so worried! Please help!

Hi, with this type of infection we need to look deep inside for all it hooks. this way you can at least not lose your data. That's why I want you to post in the HJT forum. HJT logs go here HijackThis Logs and Virus/Trojan/Spyware/Malware Removal ,click New Topic,give it a relevant Title and post that complete log.

Let me know if it went OK.

Not an unwise decision to make. Also the one I'd make here. 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.

The best proceedure is a low level format. This completely wipes the drive. Then reinstall the OS.
Use the free version of Active@ KillDisk.
Or Darik's Boot And Nuke

The best sources of Information on this are
Reformatting Windows XP
Michael Stevens Tech

Of course also feel free to ask anything on this in the XP forum. They'd be glad to help.

==============================

2 guidelines/rules when backing up

1) Backup all your important data files, pictures, music, work etc... and save it onto an external hard-drive. These files usually include .doc, .txt, .mp3, .jpg etc...
2) Do not backup any executables files or any window files. These include .exe/.scr/.htm/.html/.xml/.zip/.rar files as they may contain traces of malware. Also, .html or .htm files that are webpages should also be avoided.

Download Belarc Advisor - builds a detailed profile of your installed software and hardware, including Microsoft Hotfixes, and displays the results in your Web browser.
Run it and then print out the results, they may be handy.

Since we don't know exactly which infections we're dealing with here, we should take some precautions before we attempt to move files from the infected machine. Run the following on your clean computer, and make sure you insert your flash drives at the prompt.
Download and Run FlashDisinfector

Please download Flash_Disinfector.exe 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.


Reinstall Windows Vista
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
VIRUT
Caution: If you are considering reformatting and backing up your data, keep in mind, with a Virut infection, there is always a chance of backed up data reinfecting your system. If the data is that important to you, then you can try to salvage some of it but there is no guarantee so be forewarned that you may have to start over again afterwards if reinfected by attempting to recover your data. Only back up your important documents, personal data files, photos to a CD or DVD drive, not a flash drive or external hard drive as they may become compromised in the process. The safest practice is not to backup any executable files (*.exe), screensavers (*.scr), autorun (.ini) or script files (.php, .asp, and .html) files because they may be infected by malware. Avoid backing up compressed files (.zip, .cab, .rar) that have executable files inside them as some types of malware can penetrate and infect .exe files within compressed files too. Other types of malware may even disguise itself by adding and hiding its extension to the existing extension of file(s) so be sure you look closely at the full file name. After reformatting, scan the backed up data with your anti-virus prior to to copying it back to your hard drive.
