How to Remove vundo

The Vundo family of Trojans is one of the most common infections we find on user's computers. This infection can cause popups that include advertisements for rogue anti-spyware programs. Some common rogue antispyware programs that are advertised include WinFixer, SysProtect and WinAntiSpyware. Users are normally targeted by false positives, fake alerts, and warning of infections on their computer. An example of this type of misleading advertisement would be popups alerting users that they are infected with a blackworm virus. The most common method of infection is through outdated versions of the Sun Java platform; older versions are being exploited so it is important to firstly make sure that your Java software is fully up to date. This infection is normally detectable by users receiving popups when they use the Internet. Your antivirus program might also notify you via an alert that you have a Vundo Trojan on your computer.


Automated Removal Instructions for the Vundo or Virtumonde infection using VundoFix:

 

  1. Please print these instructions as they will be needed later when Internet access is not available.
  2. Save these instructions in word or notepad to the desktop where they can be easily found.
  3. Download Vundo Fix and save it to your desktop.
  4. When it has completed downloading, double-click VundoFix.exe to run it.
  5. Click the Scan for Vundo button.
  6. Once it's done scanning, click the Remove Vundo button.
  7. You will now receive a prompt asking if you want to remove the files, click the YES button. Once you click yes, your desktop will go blank as it starts removing Vundo.
  8. When completed, it will prompt that it will shutdown your computer, click the OK button.
  9. When the computer has shutdown, turn your computer back on.
The WinFixer and Vundo infection should now be removed from your computer.
 
If you are still having a problem then please perform the following steps:
Note: This step should only be used if the instructions in the previous steps did not remove the infection:
  1. Download VirtumundoBegone and save it to your desktop.
  2. Now reboot into Safe Mode.
    1. This can be done tapping the F8 key as soon as you start your computer
    2. You will be brought to a menu where you can choose to boot into safe mode.

what is a trojan and how to protect your computer from trojans


A Trojan horse, or Trojan, is software that is intended to perform, simultaneously, a desirable (expected) effect and a covert (unexpected) effect. Trojan horses can make copies of themselves, steal information, or harm the computer system. The term is derived from the Trojan Horse story in Greek mythology.
Symtoms of trojan in the system-mouse is blinking ,cd tray comes out on its own,computer is running slow,lot of services are executed on the computer .
Some of the common trojan are –beast trojan ,dancing pigs trojan,file sharing trojan etc
Trojan horses in this way require interaction with a hacker to fulfill their purpose, though the hacker need not be the individual responsible for distributing the Trojan horse. It is possible for individual hackers to scan computers on a network using a port scanner in the hope of finding one with a malicious Trojan horse installed, which the hacker can then use to control the target computer.[2]
A recent innovation in Trojan horse code takes advantage of a security flaw in older versions of IE explorer and Google Chrome to use the host computer as an anonymizer proxy to effectively hide internet usage. The hacker is able to view internet sites while the tracking cookies, internet history, and any IP logging are maintained on the host computer. The host computer may or may not show the internet history of the sites viewed using the computer as a proxy. The first generation of anonymizer Trojan horses tended to leave their tracks in the page view histories of the host computer. Newer generations of the Trojan horse tend to "cover" their tracks more efficiently. Several versions of Slavebot have been widely circulated in the US and Europe and are the most widely distributed examples of this type of Trojan horse.

spyware


Spyware
Any software that covertly gathers user information through the user's Internet connection without his or her knowledge, usually for advertising purposes. Spyware applications are typically bundled as a hidden component of freeware or shareware programs that can be downloaded from the Internet. Once installed, the spyware monitors user activity on the Internet and transmits that information in the background to someone else. ...
 

Symtoms
If your computer starts to behave strangely or displays any of the symptoms listed below, you may have spyware or other unwanted software installed on your computer.

I see pop-up advertisements all the time. Some unwanted software will bombard you with pop-up ads that aren't related to a particular Web site you're visiting. These ads are often for adult or other Web sites you may find objectionable. If you see pop-up ads as soon as you turn on your computer or when you're not even browsing the Web, you may have spyware or other unwanted software on your computer.
If you are getting this problem or any action please click here


My settings have changed and I can't change them back to the way they were. Some unwanted software has the ability to change your home page or search page settings. This means that the page that opens first when you start your Internet browser or the page that appears when you select "search" may be pages that you do not recognize. Even if you know how to adjust these settings, you may find that they revert back every time you restart your computer.
If you are getting this problem or any action please click here


My Web browser contains additional components that I don't remember downloading. Spyware and other unwanted software can add additional toolbars to your Web browser that you don't want or need. Even if you know how to remove these toolbars, they may return each time you restart your computer.

My computer seems sluggish. Spyware and other unwanted software are not necessarily designed to be efficient. The resources these programs use to track your activities and deliver advertisements can slow down your computer and errors in the software can make your computer crash. If you notice a sudden increase in the number of times a certain program crashes, or if your computer is slower than normal at performing routine tasks, you may have spyware or other unwanted software on your machine.

virus vundo (learn steps how to remove the vundo virus from the computer)


What is Vundo? (known as Vundo and Vundo.dldr)
Vundo is a component of an adware program that downloads and displays pop-up advertisements and eventually hijacks Internet Explorer. It is usually installed via a weblink in email, but can be contracted by a pop-up ad on the internet. The most popular web distribution is through an adware program called Winfix.
 

How do I know I have Vundo?
If a customer has pop-ups associated with Winfix, it is almost certain that they have Vundo. Most updated Antivirus will find the file names, such as awvvs.BAK, but you will not be able to delete them. Attempting to delete these files manually will most likely result in the following message: Cannot delete the following file: (File Name). Access is denied.


What does Vundo do?
Vundo contains the following payload items: HTML code, written specifically to exploit IE via IFRAME Remote Buffer A downloader executable Adware module that creates and associates DLL files Once the program is executed, an EXE file is created with a random file name that attaches itself to dozens of registry strings. Then it saves these associations within C:\Windows to every program and folder that it tied to Internet Explorer. Once this takes place, the Trojan then attaches itself to certain Windows Services registry values. For example, HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce "*WinLogon" = "[Trojan full path file name] rentime:[random number]" And this is just the tip of the iceberg. Vundo then create other registry keys that will gaurantee that user interaction will replicate itself. It then tries to call out to a website to download more components.
 


Why is Vundo so tough to get rid of?
The main problem with Vundo is that it injects an embedded DLL into the address space of several running processes. Because most of these processes are required for Windows to run, simply running a removal tool or antivirus scan will not get rid of it. Suspending the services manually will usually cause an NT Authority error and cause the system to shut down or will hard lock the system. This is why Vundo's threat level has recently been raised. Most all updated antivirus software will detect it, but will not remove it. At first It had a low distribution, damage, and low wild rating. The damage and wild rate have now been raised to medium. This is why, at first, the antivirus companies did not focus heavily on this Trojan. It was mostly just an annoyance. But this is what we do in HelpDesk.
 

Use the following updated procedures to remove Vundo and it's components.

Step One: Turn off System Restore. (DO NOT SKIP) The latest variant of Vundo loves to put an entry into the Restore Folder.
In XP:
1. Click the Start button.
2. Right-click My Computer, and then click Properties.
3. On the System Restore tab, put the check in Turn off System Restore.
4. Click Yes, then OK.
In ME:
1. Click Start > Settings > Control Panel.
2. Double-click the System icon. (If the System icon is not visible, click View all Control Panel options on the left to display it).
3. On the Performance tab, click File System.
4. On the Troubleshooting tab check Disable System Restore.
5. Click OK. Then Yes to restart the computer.

Step Two: Look for Winfix in Add/Remove Programs and Program Files
1. Click Start, Control Panel. (In 98 and ME, Start, Setting Control Panel).
2. Double-click Add/Remove Programs icon.
3. Look for Winfix. If there, click remove, or change/remove, depending on the OS.
4. Once deleted, or if it is unable to delete it, navigate to the C:\Program Files directory and delete the Winfix Folder, if there. Do not reboot.
 

Step Three: Download the necessary tools NOTE: if you cannot get online in Normal mode in XP, go to Safe mode with Networking. XP Only. First we need the removal tool from Symantec. It is located here: http://securityresponse.symantec.com/avcenter/venc/data/trojan.vundo.b.removal.tool.html Then we need the Process Explorer tool. It is located here: http://www.sysinternals.com/Utilities/ProcessExplorer.html . Save both of them to the Desktop.
 

Step Four: Boot to Safe Mode
Restart the computer. Tap F8 at the Dell screen. Choose Safe Mode from the menu. DO NOT choose Safe Mode with Networking, unless you cannot get to Normal mode to download the tools as stated in step three.
 

Step Five: Removal process
1. Open the Symantec Vundo Removal Tool. DO NOT click Start! Move the window to the upper left corner of the screen so it is not blocked by the next tool.
2. Open the Process Explorer tool. Right-click the following processes and choose Suspend. Explorer.exe Winlogon.exe rundll32.exe (may not be listed)
3. Once Explorer is suspended, you will not be able to open any programs because Explorer is required to do so. This is why we already opened the Vundo Removal tool.
4. Click the Start button on the Vundo removal tool. The tool should detect and remove the main Vundo components.
 

Step Six: Clean up
Run an Antivirus scan again. If any files are discovered, try to manually delete the found files. If you get Access Denied error, follow this process:
1. Write down the file name and the directory it lives in.
2. Boot to the Recovery Console. NOTE: If 98, boot to Command prompt only by tapping F8 and choosing that. If ME, boot to the ME cd and choose Start computer without CDROM support.
3. Once at the prompt, type cd\ and press <enter>. This should put us to a C:\ prompt.
4. Navigate to the directory of the file that cannot be deleted. For example, if the file is in the system32 folder, type cd windows\system32 and press <enter>.
5. Once in the directory, we will need to remove the attributes on the file. We will use awvvs.dll as an example. EXAMPLE: To remove all attributes on awvvs.dll, at the prompt we will type attrib -r -a -s -h awvvs.dll and press <enter>
6. Next we will rename the file. We will use awvvs.dll as an example again. EXAMPLE: To rename awvvs.dll, at the prompt we will type ren awvss.dll awvss.old and press <enter>
7. Once we have renamed it, we simply type del awvss.old and press <enter> 8. At the next prompt, type exit. Take out the CD and let the system reboot. NOTE: If 98 or ME, press CRTL+ALT+DEL. Take out the CD.

Step Seven: Turn on System Restore and create a fresh restore point. Just follow the reverse of Step One in this article to turn on System Restore. Once back on, click Start, Programs, Accessories, System Tools, System Restore. Put the dot in Create a Restore Point. Click Next. Have the customer call it whatever they can remember. Click Next. This seven step process should remove Vundo from the system.
