Help removing Trojan.BHO.H virus

[needhelp90]

My computer has been attacked by a Trojan.BHO.H virus that has disabled Kapersky Internet Security Suite and all windows protections. On advice from a friend, I downloaded Malwarebytes to try and find and remove the virus, but despite saying it's successful every time, the computer restarts with the same virus every time.

I was directed to your website and already followed the steps for what to do when infected and malware bytes doesn't work. So, I've created the necessary logs.

Hello needhelp90! Welcome to Malwarebytes' Anti-Malware Forums!

My name is Borislav and I will be glad to help you solve your problems with malware. Before we begin, please note the following:

• The process of cleaning your system may take some time, so please be patient.
  
• Follow my instructions step by step if there is a problem somewhere, stop and tell me.
  
• Stay with the thread until I tell you that your system is clean. Missing symptoms does not mean that everything is okay.
  
• Instructions that I give are for your system only!
  
• If you don't know or can't understand something please ask.
  
• Do not install or uninstall any software or hardware, while work on.
  
• Keep me informed about any changes.
  

Step 1

Please, uninstall the following applications:

1. Adobe Reader 9.3.1
   

You can read, how to do this here:

• Windows XP
  
• Windows Vista
  
• Windows 7
  

Step 2

Please go into the Control Panel, Add/Remove and for now remove ALL versions of JAVA

Then run this tool to help cleanup any left over Java

Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system.

Please download JavaRa and unzip it to your desktop.

***Please close any instances of Internet Explorer (or other web browser) before continuing!***

• Double-click on JavaRa.exe to start the program.
  
• From the drop-down menu, choose English and click on Select.
  
• JavaRa will open; click on Remove Older Versions to remove the older versions of Java installed on your computer.
  
• Click Yes when prompted. When JavaRa is done, a notice will appear that a logfile has been produced. Click OK.
  
• A logfile will pop up. Please save it to a convenient location and post it back when you reply
  Then look for the following Java folders and if found delete them.
  C:\Program Files\Java
  C:\Program Files\Common Files\Java
  C:\Windows\Sun
  C:\Documents and Settings\All Users\Application Data\Java
  C:\Documents and Settings\All Users\Application Data\Sun\Java
  C:\Documents and Settings\username\Application Data\Java
  C:\Documents and Settings\username\Application Data\Sun\Java
  

Step 3

I also see you have Viewpoint installed...

Viewpoint Manager is considered as foistware instead of malware since it is installed without users approval but doesn't spy or do anything "bad". This will change from what we know in 2006 read this article: http://www.clickz.com/news/article.php/3561546

I suggest you remove the program now. Go to Start > Settings > Control Panel > Add/Remove Programs and remove the following programs if present.

• 
  
• Viewpoint
  
• Viewpoint Manager
  
• Viewpoint Media Player
  

Step 4

• Launch Malwarebytes' Anti-Malware
  
• Go to "Update" tab and select "Check for Updates". If an update is found, it will download and install the latest version.
  
• Go to "Scanner" tab and select "Perform Quick Scan", then click Scan.
  
• The scan may take some time to finish,so please be patient.
  
• When the scan is complete, click OK, then Show Results to view the results.
  
• Make sure that everything is checked, and click Remove Selected.
  
• When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
  
• The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
  
• Copy&Paste the entire report in your next reply.
  

Extra Note:

If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process,if asked to restart the computer,please do so immediatly.

In your next reply, please include these log(s):

1. JavaRa log
   
2. Malwarebytes' Anti-Malware log
   
3. a new fresh DDS log only
   

[needhelp90]

I did all the steps for JavaRa, but the log never did open up and I was unable to find it on my computer.

I have the other 2 logs. The DDS and MBAM logs.

I did all the steps for JavaRa, but the log never did open up and I was unable to find it on my computer.

No problem.

Now:

**Note: If you need more detailed information, please visit the web page of ComboFix in BleepingComputer. **

Please note that these fixes are not instantaneous. Most infections require more than one round to properly eradicate.

Stay with me until given the 'all clear' even if symptoms diminish. Lack of symptoms does not always mean the job is complete.

Kindly follow my instructions and please do no fixing on your own or running of scanners unless requested by me or another helper.

Please download ComboFix from

Here or Here to your Desktop.

**Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved and renamed following this process directly to your desktop**

1. If you are using Firefox, make sure that your download settings are as follows:
   
   • Open Tools -> Options -> Main tab
     
   • Set to Always ask me where to Save the files.
     

[*]During the download, rename Combofix to Combo-Fix as follows:

[*]It is important you rename Combofix during the download, but not after.

[*]Please do not rename Combofix to other names, but only to the one indicated.

[*]Close any open browsers.

[*]Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

-----------------------------------------------------------

• Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause unpredictable results.
  
• Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
  

  -----------------------------------------------------------

  
  

• Close any open browsers.
  
• WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
  
• Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.

[*]When finished, it will produce a report for you.

So, as you can see from the log, it's claiming there is no infection anymore. Is this correct? We will wait to hear back from you. We want to be sure this is completely gone

How are things there?

[needhelp90]

What things should I be looking for?

[Maniac]

Your problem maybe?

[needhelp90]

Well, Malware Bytes doesn't appear to be finding anything anymore and Kapersky is back to working and updating without problems. So, it appears to be back to normal. Any more recommendations? Any other anti-virus programs you recommend, maybe avast home edition or a firewall to go with it or anything?

Also, do you think using Firefox is better than IE?

Thanks.

[Maniac]

Please manually update Kaspersky and perform a full scan. Let me know about the resaults.

Any other anti-virus programs you recommend, maybe avast home edition or a firewall to go with it or anything?

Kaspersky is a better choise than Avast.

Also, do you think using Firefox is better than IE?

Much, much better.

[needhelp90]

Kapersky and Malware bytes have both done full scans now and both have come back all clear. I've downloaded Firefox. I was also wondering if it's ok to download adobe and java again? What do you think allowed this virus in?

Thanks for all of your help.

[Maniac]

Nice job!

What do you think allowed this virus in?

You can find details here:

Last steps:

Step 1

* Go to start > run and copy and paste next command in the field:
