Hello,
 
This is my first time posting on this site so please bear with me if I make any errors.
 
I have been having a major problem with my computer over the past month or so.
After internet explorer and outlook kept crashing and the dreaded blue screen of death came up I ran a scan with various scanners to no avail. The only scanner that finds something is Trojan Killer which finds what I am told is a Trojan in the following file:
 
c:\windows\system32\explorer.exe - pws.lineage.25424
 
Trojan Remover cannot remove this trojan so I have completely removed and restored my computer to factory settings 5 times now, after which the scan shows no virus. Yet after around a day or two the same Trojan pops up (I run a scan every day now).
 
I simply cannot understand where this Trojan is coming from. I have Panda Antivirus, I do not use malicious websites, I have even created a separate user account that does not have administrator privileges in the hope that it will not 'get through'. I initially thought it was my use of utorrent but it seems that it is not because I have been using this for a year now without problems and I never download .exe or zipped files.
 
What the hell am I to do??? I cannot keep restoring windows because it takes so much time and because I work from my computer and a day's work lost is a big problem. Is this coming from a site? A weakness in my system? How can I remove it without completely restoring windows?
 
I have Windows 8, 64bit, running on HP Envy dv7 laptop with Panda Global Protection 2014. 
 
Any help would be much, much appreciated!

Please do the following in the order it is requested.

 

Please download and run RKill
 
RKill is an easy to use tool that kills known processes and removes Windows Registry entries that stop a user from using their normal security applications.  These settings will remain until the computer is rebooted, for this reason you must run the security application before the computer is rebooted.  
 
Please download RKill and install it.
 
When RKill is run it will display a console screen similar to the one below:
 
RKill_zps2e34d4b8.png
 
When RKill has finished running a log will be displayed showing all of the processes that were terminated by RKill.
 
Attention:  At this time you need to run your security applications listed below.
 
While RKill is running you may see a message from the malware stating that the program could not be run because it is a virus or is infected.  This is the malware trying to protect itself.  Two methods that you can try to get past this and allow RKill to run are:
 
1)  Rename Rkill so that it has a .com extension.
 
2)  Download a version that is already renamed as files that are commonly white-listed by malware. The main Rkill download page contains individual links to renamed versions.  
 
After the application has run successfully you should reboot the computer to restore the processes and Windows Registry entries. 


Please run Malwarebytes AntiMalware

 
Please download Malwarebytes Anti-Malware.  After clicking on the link the download will start automatically.
 
1)  Double-click on mbam-setup.exe, then click on Run to install the application, follow the prompts through the installation.
 
2)  Malwarebytes will automatically open.  If this is the first time you have run this version of Malwarbytes you will see an image like the one below.

Click on Update Now, after Malwarebytes is updated click on Scan.
 
If this isn't the first time you have run this version, then you will see an image like the one below.  Click on Scan
 
mbam1_zps98e7fba9.png
 
You will be prompted to update Malwarebytes, to do so click on Update Now.
 
 mbam2_zps85f38f0c.png
 
3)  The scan will automatically run now.

4)  When the scan is complete the results will be displayed.  Click on Quarantine All, then click on Apply Actions
 
mbam4_zps23e52ad4.png
 
 
5)  To complete any actions taken you will be asked if you want to restart your computer, click on Yes
 
 mbam4_zps490948cc.png
 
6)  Please post the Malwarebytes log.
 
To find your Malwarebytes log,download mbam-check.exe from here and save it to your desktop.
 
To open the log double click on mbam-check.exe on your desktop.  When the log opens, scroll down toward the bottom of the log to Quarantined Items.  Copy and paste this in your next post.
 
 
Please run TDSSKiller.
 
Please download TDSSKiller from here and save it to your Desktop.
 
1.  Doubleclick on TDSSKiller.exe to run the application, then click on Change parameters.

3.  Click Start Scan and allow the scan process to run.

5.  Click on Reboot computer.
 
Please copy the TDSSKiller.[Version]_[Date]_[Time]_log.txt file found in your root directory (typically c:\) and paste it into your next reply.


Please run the ESET OnlineScan

This scan takes quite a long time to run, so be prepared to have the time to allow this to run till it is completed.

***Please note. If you run this scan using Internet Explorer you won't need to download the Eset Smartinstaller.***

  • Click on this link to open ESET OnlineScan in a new window.
  • The ESET Online Scanner page will open, click on Yes, I agree to the trems of use, then click on Start, the scan will now begine.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on esetsmartinstaller_enu.exe to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the esetsmartinstaller_enu.png icon on your desktop.
  • Check "YES, I accept the Terms of Use."
  • Click the Start button.
  • Accept any security warnings from your browser.
  • Under scan settings, check "Scan Archives" and "Remove found threats"
  • Click Advanced settings and select the following:
    • Scan potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, click List Threats
  • Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Click the Back button.
  • Click the Finish button.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

It is most likely that Trojan Killer is wrong. It is simply not considered reliable for finding and removing malware....but very good at cleaning your billfold.

 

If your Panda is not reporting malware then you likely do not have any.

 

Following dc3's instruction should convince you of the above.

 

Of course, if you have downloaded and installed freeware then it is likely you will have adware.... that is the norm for using freeware. So the scans won't

be a total waste of time.
