Hello I have an
HP ENVY 14 Notebook PC
Intel® Core™ i7 CPU Q700 @ 1.60 GHz
4 GB ram and 64 bit operating system

I recently stumbled upon a Trojan Win32/Tracur.av & Trojan:DOS/Alureon.A, each time I start up my computer my microsoft security essential says hey you're at risk and removes the Alureon.A each time. I think this means the virus is deeper than I thought. I've ran microsoft security essentials full scan and malwarebytes and they keep saying they remove it but then the next time I run those programs it says it removes it again... So anyway Microsoft Security essentials told me to download windows defender offline but I don't have a separate computer and its getting really hard for me to do this. Any help please?

you only need to disable Microsoft Security Essentials

Open the user interface > settings > real time protection > uncheck the box beside "turn on real time protection"

it depends on the infection on your machine, I've known that to happen before, so it's not unusual

Please run the following

Refer to the ComboFix User's Guide

  • Download ComboFix from the following location:

    Link

    * IMPORTANT !!! Place ComboFix.exe on your Desktop
  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with ComboFix.
    You can get help on disabling your protection programs here
  • Double click on ComboFix.exe & follow the prompts.
  • Your desktop may go blank. This is normal. It will return when ComboFix is done. ComboFix may reboot your machine. This is normal.
  • When finished, it shall produce a log for you. Post that log in your next reply

    Note:
    Do not mouseclick combofix's window whilst it's running. That may cause it to stall.


    ---------------------------------------------------------------------------------------------
  • Ensure your AntiVirus and AntiSpyware applications are re-enabled.

    ---------------------------------------------------------------------------------------------

NOTE: If you encounter a message "illegal operation attempted on registry key that has been marked for deletion" and no programs will run - please just reboot and that will resolve that error.

Hey Cat so far I'm 32% done but it says there's 6 infected files.
1) Win64/olmarik.ak trojan
2) Win32/Olmarik.AFK trojan
3) Win64/Olmarik.AN trojan
4) a variant of win32/rootkit.kryptik.pr trojan
5) a variant of win64/Olmarik.AM trojan
6) a variant of win32/Olmarik.AYI trojan

This sucks :( and I'm still scanning the rest of my computer.
