Persistent URL:Mal infection.

[iMalibuz0r]

Hi, I keep getting this warning every few minutes or so.

This is what I get on the site:

Code: [Select]

Infection Details
URL: http://hamuraxula.net/feed/index.php?pid2
Process: C:\Program Files (x86)\Common Files\Certificate\CertificateKey.exe
Infection: URL:Mal
The url keeps changing almost every time the warning comes up.

I don't know what is certificatekey.exe, it was running in taskmanager, I just closed it and haven't noticed those warnings pop up again.

Now, I want to know more about this process. I googled it and didn't find anything that helped me, or something that explain what it is. I would be glad if someone could explain what it is, and if it's safe to remove.


Thanks.


(Edit: Forgot to mention, before getting this warnings, I got a trojan: (Sorry, can't remember the name by heart) Win32:Trojan/Sirefef.p (I think it was p at the end of it)
So I successfully removed that with avast, but then those warnings I originally mentioned started happening.

Nope it looks like a new redirect variant, first time I have seen it

Prior to OTL quarantining it could you upload it to Avast as possible malware

Open Avast and go to the virus chest
Right click the blank area and select add


Navigate to C:\Program Files (x86)\Common Files\Certificate\CertificateKey.exe


Select the file


Right click the file in the chest and select submit to virus labs


Once done manually update the virus definitions to send it

THEN

[essexboy]

How is the computer behaving now ?

[iMalibuz0r]

Yup, seems like the problem is gone! Thanks a lot!!

[essexboy]

If all is still OK tomorrow, let me know and I will remove my tools

 

[iMalibuz0r]

Everything seems to be OK! Thanks again essexboy.

[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

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

• Click Start.
• Open My Computer.
• Select the Tools menu and click Folder Options.
• 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.

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
