Win32:Downloader-PKU Help

[SteveinMD]

No problems to report.  You guys rock!

[essexboy]

Subject to no further problems   

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems 

Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:

Run OTL

• Under the Custom Scans/Fixes box at the bottom, paste in the following
  

  :Commands
  [resethosts]
  [emptytemp]
  [Reboot]

• Then click the Run Fix button at the top
  
• Let the program run unhindered, reboot the PC when it is done

Remove ComboFix

• Hold down the Windows key + R on your keyboard. This will display the Run dialogue box
  
• In the Run box, type in ComboFix /Uninstall (Notice the space between the "x" and "/") then click OK
  
  
  
  
• Follow the prompts on the screen
• A message should appear confirming that ComboFix was uninstalled

Run OTL and hit the cleanup button.  It will remove all the programmes we have used plus itself. 

We will now confirm that your hidden files are set to that, as some of the tools I use will change that

• Go to control panel
• Select folder options (Appearance > Folder options in category view)
• Select the View Tab.
• Under the Hidden files and folders heading select Do not show hidden files and folders.
  
• Click Yes to confirm.
• Click OK.

Your Java is out of date. Older versions have vulnerabilities that malware can use to infect your system.
Please follow these steps to remove older version of Java components and upgrade the application.

 Upgrading Java:

• Go to this site  and click Do I have Java
  
• It will check your current version and then offer to update to the latest version

SPRING CLEAN

To manually create a new Restore Point
 

• Go to Control Panel and select System
  
• Select System
  
• On the left select System Protection and accept the warning if you get one
  
• Select System Protection Tab
  
• Select Create at the bottom
  
• Type in a name i.e. Clean
• Select Create
  

Now we can purge the infected ones

• GoStart > All programs > Accessories > system tools
  
• Right click Disc cleanup and select run as administrator
  
• Select Your main drive and accept the warning if you get one
  
• For a few moments the system will make some calculations
• Select the More Options tab
  
• In the System Restore and Shadow Backups select Clean up
  
• Select Delete on the pop up
  
• Select OK
• Select Delete

Now that you are clean, to help protect your computer in the future I recommend that you get the following free programmes:

Malwarebytes.  Update and run weekly to keep your system clean

Download and install FileHippo update checker and run it monthly it will show you which programmes on your system need updating and give a download link

It is critical to have both a firewall and anti virus to protect your system and to keep them updated. To keep your operating system up to date visit

• Microsoft Windows Update

To learn more about how to protect yourself while on the internet read our little guide  How did I get infected in the first place ?

Keep safe  :wave:

It turns out that the malware damaged or removed the BITS service (Background Intelligent Transfer Service) which affects my ability to run Windows Updates.  Is this something that can be fixed?

[DavidR]

There will be a bit of a delay until essexboy is back on-line later this afternoon (almost 10:40am in the UK).

Are you getting any errors when you try to use windows update ?
It may be that the service is disabled rather than damaged or removed, check Windows Run and type services.msc and look for the Background Intelligent Transfer Service - is it set to Automatic and is it running ?

If not set it to Automatic and click the Start button. You may need administrative privileges to do this.

If the above doesn't resolve it, I'm sure essexboy has some fixes up his sleeve.

Same problem here...

Ok sorry, i thought it was the same problem. ;o)
->

[SteveinMD]

When I try to start the BITS service it says...

Windows could not start the BITS service on Local Computer.  Error 126: The specified module could not be found.

[DavidR]

No problem, whilst it might be the same problem, the fixes are unique to the particular system and helping two in the same topic can confuse.

[essexboy]

OK I have an answer for that

But it did not show as a problem in FSS

Right click the following link and select "Save Target As...." and save to the desktop
https://dl.dropbox.com/u/73555776/bits.reg
Then right click the registry file and select merge
Accept the warnings and reboot

Now try

[DavidR]

When I try to start the BITS service it says...

Windows could not start the BITS service on Local Computer.  Error 126: The specified module could not be found.

OK, I found this on that error, BITS error 126 windows 7, if that doesn't help, hopefully essexboy will be able to get back to the topic soon.

Edit: he's already here.

[SteveinMD]

Looks perfect, thank you.  I won't be able try it until about 10 hours from now.  I'll post the results.

[essexboy]

The MS link is a bit drastic... Reformat for one registry key missing

[SteveinMD]

Understood.  I'll try your fix.

[DavidR]

Yes MS can often suggest a sledge hammer to crack a nut, that way they don't have to give any detailed information to resolve the problem.
