Recommended Posts

Hello, my computer has been infected by Trojan:W32/Agent. I have ran security check with advanced system care 6 and it found Trojan.Agent in svchost.exe... (my avira antivir doesn't detect that)... ASC will delete virus every time, but it's always back on reboot and it takes 25% of my resources so it slows down my computer. I really don't know what to do and i would be so glad if u helped me :)

I attached "dds" and "attach"

Please create a new system restore point before running Malwarebytes Anti-Rootkit if you can.

Download Malwarebytes Anti-Rootkit from HERE

  • Unzip the contents to a folder in a convenient location.
  • Open the folder where the contents were unzipped and run mbar.exe
  • Follow the instructions in the wizard to update and allow the program to scan your computer for threats.
  • Click on the Cleanup button to remove any threats and reboot if prompted to do so.
  • Wait while the system shuts down and the cleanup process is performed.

I did many system scans and everytime it gives same.. If i run scan after scan without reboot it doesn't find anything anymore, but when i reboot it always come back. I also turned my antivirus off because it was blocking something from registry but it didn't help anything. There's logs attached.

Please read the directions carefully so you don't end up deleting something that is good!!

If in doubt about an entry....please ask or choose Skip!!!!

Don't Delete anything unless instructed to!

If you get the warning about a file UnsignedFile.Multi.Generic or LockedFile.Multi.Generic please choose

Skip and click on Continue

Please download and run ComboFix.

The most important things to remember when running it is to disable all your malware programs and run Combofix from your desktop.

Please visit this webpage for download links, and instructions for running ComboFix

http://www.bleepingcomputer.com/combofix/how-to-use-combofix

Ensure you have disabled all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

Information on disabling your malware programs can be found Here.

Make sure you run ComboFix from your desktop.

Give it at least 30-45 minutes to finish if needed.

Please include the C:\ComboFix.txt in your next reply for further review.

---------->NOTE<----------

If you get the message Illegal operation attempted on registry key that has been marked for deletion after you run ComboFix....please reboot the computer, this should resolve the problem. You may have to do this several times if needed.

Ok I ran Combofix and it rebooted my computer, on start it said something about registrys and "svc" something and my computer started normally as it used to start. But nothing else didn't work then so I restarted my computer and it started slowly again with that svchost taking 25% of my resources. Should I've done something before restarting my computer? Got log.

What do you know about this???

C:\Windows\Setup\scripts\faXcooL.exe (HackTool.Wpakill) -> Toimintoja ei suoritettu.

faXcooL.exe is a Hack tool used for disabling Windows Genuine Advantage Checks, it is what they call a "Remove WAT" tool, if your computer found this, either you installed a pirated version of Windows or whoever installed Windows on your computer used a pirated copy. Or you or someone downloaded the tool to Remove WAT, or you downloaded it on accident.

It says that "Nothing was done" Well I don't know about that one because I bought my computer from friend who bought new computer for himself. Could this be a problem? I've had this computer like 6 months now and didn't have any problems untill now.

I ran quick scan as you said and got log and I translated there some english so you could understand what it says :).. I tried to change programs language to english but apparently my computer skills weren't high enough :( It found only that Trojan.Agent.Gen and "deleted" it.. After reboot Malwarebytes Anti-Malware put instantly "Trojan.Agent.Gen" and "Trojan.Agent.cn" to quarantine.
