Last night I encountered an issue when I received the blue screen and my Win7 laptop shut down, after that, I tried booting in safe mode (which works most of the time, but sometimes the blue screen reappears) and noticed Kaspersky was not able to open. When I tried opening it from the start menu, nothing happens and the same goes for when I follow the prompt from Windows Defender to turn on my anti-virus: nothing but the same trojan alert. Windows defender informs me of the inruy.h Trojan, and even after removing it, it doesn't seem to do anything, as it will pop up again if I try to open Kaspersky, or generally by itself. Is there any way to permanently remove it? I've tried Malwarebytes, and it doesn't seem to pick up anything when I tried it last night, though I know the virus is still present, because windows defendor will alert me of this every time I try to open my anti-virus - not to mention the blue screen of deaths that show up when I boot up normally.

I am able to start safe mode with networking if that's a start, though I'm not sure if the use of the internet on the infected computer with this trojan would be ideal. Anyone care to help me out with this tedious issue? If I were to require a new program/file - the usb slots on the computer does not seem to pick up any device in My Computer, which might be problematic unless using internet in safe mode is okay. Though I generally have no clue as to how to rectify this issue.

Thanks in advance for any assistance.

Edit: Below is the log for the latest Malwarebytes full scan. 5 new objects arose, yet even after it finished, the issue of the unruy.h trojan still remained.

Sorry, forgot to include the log from MBAM beforehand. Hopefully this'll be of some use.

Hello you will need to run these. Also your MBAM needs am update.

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.4.0.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.


Now do an online scan.
Please perform a scan with Eset Online Antiivirus Scanner.
This scan requires Internet Explorer to work. Vista/Windows 7 users need to run Internet Explorer as Administrator.
To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run As Administrator from the context menu.
  • Click the green Posted Image button.
  • Read the End User License Agreement and check the box:
  • Check Posted Image.
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Check Posted Image
  • Check Remove found threats and Scan potentially unwanted applications. (If given the option, choose "Quarantine" instead of delete.)
  • Click the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer.
  • If offered the option to get information or buy software at any point, just close the window.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • When the scan completes, push Posted Image
  • Push Posted Image, and save the file to your desktop as ESETScan.txt.
  • Push the Posted Image button, then Finish.
  • Copy and paste the contents of ESETScan.txt in your next reply.
Note: A log.txt file will also be created and automatically saved in the C:\Program Files\EsetOnlineScanner\ folder.
If you did not save the ESETScan log, click Posted Image > Run..., then type or copy and paste everything in the code box below into the Open dialogue box:

C:\Program Files\ESET\EsetOnlineScanner\log.txt
  • Click Ok and the scan results will open in Notepad.
  • Copy and paste the contents of log.txt in your next reply.
-- Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

NOTE: In some instances if no malware is found there will be no log produced.
