Running pretty good Thanks

[CatByte]

did that fix remove the error message on reboot?

Please run the following:

Your Java is out of date, so go to Start > Control Panel > Programs and Features > scroll down to the Java installation and Remove it, now download the latest Java version 7 update 5 and install it: http://java.com/en/download/index.jsp

NEXT

Visit ADOBE and download the latest version of Acrobat Reader (version X)

Having the latest updates ensures there are no security vulnerabilities in your system.

[knightmaster]

Error msg is gone!

I have already uninstalled and reinstalled java. Do I need to do it again???

[knightmaster]

it says java 7 ver 5...???

[CatByte]

oh no, my apologies, I missed the post where I asked you to do that (long thread!)

any outstanding issues or is everything running well now?

[knightmaster]

Running much better. May I ask how do you read the logs?

[CatByte]

ok, that's good, we just have some housekeeping to do.

There are "schools" that teach malware removal where you learn how to read the logs. Basically it's a lot of research, to see what every line means and should it be there. After a while you recognize the good stuff so the bad stuff is easier to see. It takes a lot of time and patience and several rounds (as you have seen)with different tools, as not every tool will remove everything. Different variants of similar infections can have different reactions on different machines, so it's a bit of trial and error with the more stubborn infections. Thankfully, this community has brilliant tool developers who work tirelessly to keep the tools updated to make our lives easier.

please do the following:

You can delete the system look logs and program from your desktop.

NEXT

Follow these steps to uninstall Combofix

• Make sure your security programs are totally disabled.
  
• Click START then RUN
  
• Now copy/paste Combofix /uninstall into the runbox and click OK. Note the space between the ..X and the /U, it needs to be there.
  

NEXT

Clean up with OTL:

• Double-click OTL.exe to start the program.
  
• Close all other programs apart from OTL as this step will require a reboot
  
• On the OTL main screen, press the CLEANUP button
  
• Say Yes to the prompt and then allow the program to reboot your computer.
  

If there are any logs/tools remaining on your desktop > right click and delete them.

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. KeePass is a small utility that allows you to manage all your passwords.
  
• 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?.

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.

[knightmaster]

Ok couple more questions then u can tell me how to close this thread. Do I keep TFC and CC Cleaner and run them periodically?

[CatByte]

TFC and CCleaner pretty much perform the same function, keep the one you prefer, don't use the registry cleaner function of CCleaner if you choose to keep that one, it is not recommended to do anything to the registry.

I need to close the thread myself, I just notify a moderator that it needs archiving.

stay safe
