Infected computer


Recommended Posts

Hi! Yesterday I got infected by several malware. My browsers were hijacked, I got bsods, was unable to install Avira etc. I got most of them removed by several tools including MBAM, Adwcleaner, Roguekiller but I still think there's something in my computer that doesn't belong to it. My computer gets strange frozens that have not happened before yesterday's infection, Roguekiller reporting Hook.IRP in two different .sys file that changes in different scan times, also in Temp folder there comes suspicious "dllnt_dump.dll" at every boot though I empty temp folder. And though I'm not an expert, but I think there are something wrong also in OTL log. I will post it here also if you need it. And thanks in advance for helping me to get my computer clean :)

dllnt_dump.dll is not classed as malicious -  http://www.freefixer.com/library/file/dllnt_dump.dll-166202/


mountmgr.sys is not classed as malicious either although like most drivers it can cause BSOD and or freezes... https://support.microsoft.com/en-us/kb/2614892


I do not see any obvious malware or infection in your logs,


Can you post the logs from OTL, also Combofix log C:\Combofix.txt 


Also zip up and attach Qoobox folder from Combofix  C:\Qoobox


Can you also check if this folder is on your system C:\Windows\Minidump if so zip up and attach that folder...


Thank you,

Thanks for the reply, run the following to clean up:


Download "Delfix by Xplode" and save it to your desktop.

Or use the following if first link is down:

"Delfix link mirror"

Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator

Make Sure the following items are checked:

  • Remove disinfection tools
  • Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created.
  • Reset system settings

Now click on "Run" and wait patiently until the tool has completed.

The tool will create a log when it has completed. We don't need you to post this.

Any remnant files/logs from tools we have used can be deleted…
