Help Remove Win32/Olmarik.TDL4 Trojan: Steps to Exterminate Win32/olmarik Trojan.

What Does Win32/Olmarik.TDL4 Do?

Someone has run a scan with ESET, and here’s the report:

‘Threat: Win32/Olmarik.TDL4 trojan
Object: unable to clean
I noticed a few odd things after I got infected such as my tray being all on the taskbar, my pinned taskbar programs gone, and my start menu wiped of all settings / history. I am not sure if that is relevant.

At first I was unable to open my task manager and programs would close very quickly on their own, but after cleaning the other infections all the symptoms seem to have stopped.
I don't see any enduring symptoms now. My computer isn't slowing down, the internet works fine, and nothing seems out of place. I do not know exactly what this virus is doing other than existing and being a security threat but I still feel very uneasy with it here.’

There is certainly nothing furious happening at the very beginning of win32/olmarik.tdl4’s infiltration since additional components are staying ready to be put in place and more commands for further damage should be reached to olmarik.TDL4 via a backdoor it opens. The silence stage at the very beginning simply paralyzes PC users to ignore the immediacy to shake off win32/olmarik.tdl4 from the attacked system and thus put them into mess as what the report described by one of the victims of Win32/Olmarik.TDL4 trojan who left the Trojan horse behind at the very first stage:

‘My only problem is that Nod32 is giving this popup notification every time the system boots: "Operating memory - Win32/Olmarik.TDL4 trojan - unable to clean" as well as intermittent popups showing random blocked website addresses at odd times, like when I'm not actively using a web browser. This has been going one for 1-2 days, I can't pinpoint exactly when it started. I also had several BSOD today (for the first time ever on this laptop, which is fairly new) -- once while copying data to a new external hard drive, once while running CCleaner, and one other time when I wasn't doing anything in particular. No other symptoms that I've noticed.

I ran MBAM, which showed two "Trojan.Agent" entries (one File and one Memory Process) and prompted a reboot when I tried to remove them, but after the reboot I reran MB and the same entires were found again. Also ran Super AntiSpyware with similar results. I ran TDSSKiller as well, which showed "Rootkit.Boot.Pihar.c" but was uanble to remove it (I declined the "Write standard boot code?" prompt.)’

This is what Win32/Olmarik.TDL4 does, and actually, it can commit more beyond our imagination. All evils come out of backdoor that chiseled by the Trojan horse:
  1. Backdoor allows tracking cookies to come into the system for information theft; with more cookies getting in, you will stuck up in the middle of scanning;
  2. Browser malware that is sensitive to vulnerability on web apps or programs installed in the system would come in with little effort to arouse redirect issue and annoying pop ups;
  3. More commands will be conveyed to Win32/Olmarik.TDL4 via the backdoor in a bid to weaken security defense and block installed security utilities from exterminating it.
  4. With more original key values being modified by olmarik.tdl4 and more infections, system is worn out to get blue screen of death and the like.
Don’t want your information being exposed to spammers to involve yourself into browser mess and regain a healthy computer back?
