I downloaded the free STOPzilla software and it says that it found 10 errors.
The first is a GASF Trojan Virus in the Registry Key
Location: HKLM\SYSTEM\CurrentControlSet\Services\rvcfv
HKLM\SYSTEM\CurrentControlSet\Services\rvcfv "ImagePath"="System32\drivers\dbwyp.sys"
HKLM\SYSTEM\CurrentControlSet\"Start"= 0x00000000(0)"

File:
C:\windows\system32\drivers\dbwvp.sys

I ran Norton Internet Security, Malwarebytes, CCleaner, all up to date and they did not locate this virus. My question is this a true virus or just a scam that STOPzilla wants you to buy their product?

personally, I'd uninstall stopzilla, but that's up to you


Please run the following program:


Download ComboFix from one of the following locations:
Link 1
Link 2

VERY IMPORTANT !!! Save ComboFix.exe to your Desktop

* IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here
  • Double click on ComboFix.exe & follow the prompts.
As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.

  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

Posted Image

  • Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Posted Image

  • Click on Yes, to continue scanning for malware.
When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.
Notes:
1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.
2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.

I saved the combofix to my Desktop and then hit Run and 2 errors keep pooping up not allowing it to install.

Windows can not find 32788R22FWJFW\nircmd-cfxxe
Windows can not find NIRCMD

I tried both links that you gave me, and both came up w/ the errors.

Thanks-

Please delete the copy of ComboFix that you have on your desktop and download a fresh copy, but rename it to iexplore before saving it to your desktop, now try running it, if it still wont run, try running it in safe mode.


To Enter Safemode
  • Go to Start> Shut off your Computer> Restart
  • As the computer starts to boot-up, Tap the F8 KEY repeatedly,
  • this will bring up a menu.
  • Use the Up and Down Arrow Keys to scroll up to Safemode
  • Then press the Enter Key on your Keyboard
  • go into your usual account

  • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before following the steps below.
  • They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
Copy/paste the text inside the Codebox below into notepad:

Here's how to do that:
Click Start > Run type Notepad click OK.
This will open an empty notepad file:

Copy all the text inside of the code box - Press Ctrl+C (or right click on the highlighted section and choose 'copy')

http://www.bleepingcomputer.com/forums/topic382496.html/page__view__findpost__p__2157701

Collect::
c:\windows\system32\drivers\guue.sys

Driver::
botl

Now paste the copied text into the open notepad - press CTRL+V (or right click and choose 'paste')

Save this file to your desktop, Save this as "CFScript"


Here's how to do that:

1.Click File;
2.Click Save As... Change the directory to your desktop;
3.Change the Save as type to "All Files";
4.Type in the file name: CFScript
5.Click Save ...

Posted Image
  • Referring to the screenshot above, drag CFScript.txt into ComboFix.exe.
  • ComboFix will now run a scan on your system. It may reboot your system when it finishes. This is normal.
  • When finished, it shall produce a log for you.
  • Copy and paste the contents of the log in your next reply.

CAUTION: Do not mouse-click ComboFix's window while it is running. That may cause it to stall.

log appears to be clean

clearing the Java cache removes the infection found by ESET

I would consider uninstalling Stopzilla, you don't need it, stick with your AV and Malwarebytes

please do the following:


You can delete the DDS and GMER logs and programs from your desktop.

Below I have included a number of recommendations for how to protect your computer against malware infections.

  • It is good security practice to change your passwords to all your online accounts on a fairly regular basis, this is especially true after an infection. Refer to this Microsoft article
    Strong passwords: How to create and use them
    Then consider a password keeper, to keep all your passwords safe.

  • Keep Windows updated by regularly checking their website at :
    http://windowsupdate.microsoft.com/
    This will ensure your computer has always the latest security updates available installed on your computer.

  • Make Internet Explorer more secure
    • Click Start > Run
    • Type Inetcpl.cpl & click OK
    • Click on the Security tab
    • Click Reset all zones to default level
    • Make sure the Internet Zone is selected & Click Custom level
    • In the ActiveX section, set the first two options ("Download signed and unsigned ActiveX controls) to "Prompt", and ("Initialize and Script ActiveX controls not marked as safe") to "Disable".
    • Next Click OK, then Apply button and then OK to exit the Internet Properties page.

  • Download TFC to your desktop
    • Close any open windows.
    • Double click the TFC icon to run the program
    • TFC will close all open programs itself in order to run,
    • Click the Start button to begin the process.
    • Allow TFC to run uninterrupted.
    • The program should not take long to finish it's job
    • Once its finished it should automatically reboot your machine,
    • if it doesn't, manually reboot to ensure a complete clean
    It's normal after running TFC cleaner that the PC will be slower to boot the first time.

  • WOT, Web of Trust, warns you about risky websites that try to scam visitors, deliver malware or send spam. Protect your computer against online threats by using WOT as your front-line layer of protection when browsing or searching in unfamiliar territory. WOT's color-coded icons show you ratings for 21 million websites, helping you avoid the dangerous sites:
    • Green to go
    • Yellow for caution
    • Red to stop
    WOT has an addon available for both Firefox and IE

  • Keep a backup of your important files - Now, more than ever, it's especially important to protect your digital files and memories. This article is full of good information on alternatives for home backup solutions.

  • ERUNT (Emergency Recovery Utility NT) allows you to keep a complete backup of your registry and restore it when needed. The standard registry backup options that come with Windows back up most of the registry but not all of it. ERUNT however creates a complete backup set, including the Security hive and user related sections. ERUNT is easy to use and since it creates a full backup, there are no options or choices other than to select the location of the backup files. The backup set includes a small executable that will launch the registry restore if needed.

  • In light of your recent issue, I'm sure you'd like to avoid any future infections. Please take a look at this well written article:
    PC Safety and Security--What Do I Need?.


**Be very wary with any security software that is advertised in popups or in other ways. They are not only usually of no use, but often have malware in them.


Thank you for your patience, and performing all of the procedures requested.

Please respond one last time so we can consider the thread resolved and close it, thank-you.
