Virtumonde Removal Tool - We use multiple tools to ensure the virus is 100% removed from your system!

Virtumonde commonly known as Vundo is typically caused either by opening an e-mail attachment carrying the trojan, or through a variety of browser exploits, including vulnerabilities in popular browser plug-ins, such as Java. Many of the popups advertise fraudulent programs such as AntiSpywareMaster, WinFixer, AntiVirus 2009.

There are two main components to Virtumonde.dll which are Browser Helper Objects and Class ID. Each of these components is in the Windows Registry under HKEY LOCAL MACHINE, and the file names are dynamic. It attaches to the system using bogus Browser Helper Objects and DLL files attached to winlogon.exe and explorer.exe and more recently lsass.exe.

Vundo inserts registry entries to suppress Windows warnings about the disabling of firewall, antivirus, and the Automatic Updates service, disables the Automatic Updates service and quickly re-disables it if manually re-enabled, and attacks Malwarebytes' Anti-Malware, Spybot Search & Destroy, Lavasoft Ad-Aware, HijackThis, and several other malware removal tools. It frequently hides itself from Vundofix & Combofix. Rather than pushing fake antivirus products, the new "ad" popups for the drive-by download attacks are copies of ads by major corporations, faked so that simply closing them allows the drive-by download exploit to insert the payload into the user's computer. (Fortunately, this is hindered, if not prevented altogether by Vista's User Account Control feature.) Its filenames are categorized by having the "hidden" flag set and being .dll files with 8-character randomly arranged names alternating consonants and vowels.

 Symptoms

Since there are many different varieties of Vundo trojans, symptoms of Vundo vary widely, ranging from the relatively benign to the severe. Almost all varieties of Vundo feature some sort of pop-up advertising as well as rooting themselves to make them difficult to delete.

Computers infected exhibit some or all of the following symptoms:

* Vundo will cause the infected web browser to pop up advertisements, many of which claim a need for software to fix system "deterioration".

* The desktop background may be changed to the image of an installation window saying there is adware on the computer.

* The screensaver may be changed to the Blue Screen of Death.

* In the Display Properties Control Panel, the background and screensaver tabs are missing because their "Hide" values in the Registry were changed to 1.

* Both the background and screensaver are in the System32 folder, however the screensaver cannot be deleted.

* Windows Automatic Updates (and other web-based services) may also be disabled and it is not possible to turn them back on.

 * Some firewalls or antivirus software may also be disabled by the virus leaving the system even more vulnerable. Especially, it disables Norton AntiVirus and in turn uses it to spread the infection. Norton will show prompts to enable phishing filter, all by itself. Upon pressing OK, it will try to connect to real-av.org and try to download more malware.

* Popular anti-malware programs may be deleted or immediately closed upon loading.

* Web access may also be negatively affected. Vundo may cause many websites to be inaccessible.

* Google search links may be directed to rogue antispyware sites, which can be avoided by copy and pasting addresses

* Vundo may cause webpages to fail to load after sessions of browsing and present a blank page in the browser instead of the webpage. When this happens any programs may also fail to start and it may become impossible to use windows shutdown.

* The hard drive may start to be constantly accessed by the winlogon process, thus periodic freezes may be experienced.
