Hi all

Laptop is running W7HP. Apparently the user web onto some dodgy websites and now is infected with W32/Agent.BNEX!tr.rkit.

THe laptop is using FortiClient as AV.

The AV detection comes up every boot. I have found some files which reside in C:\Users\xxx\Local\ and also \Temp.

I also have a "uwnblgjk.exe" in the Startup menu, and associated startup reg keys that keep coming back. If I try to delete the exe I get the error:

The action can't be completed because the file us open in Host Process for Windows Services.

I have tried scanning with Malwarebytes, SuperAntiSpyware and ComboFix. All found some things which were removed, but are now coming up clean although the infection is still there.

Please help!

You may already have this tool. Run it and if asked to update please do so.

Please download ComboFix from any of the links below, and save it to your desktop. For information regarding this download, please visit this web page: http://www.bleepingcomputer.com/combofix/how-to-use-combofix

* IMPORTANT !!! Save ComboFix.exe to your Desktop

IMPORTANT....

1. Close any open browsers.

2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

3. Do not install any other programs until this if fixed.

Double click on ComboFix.exe & follow the prompts.
  • When finished, it will produce a report for you.
  • Please post the C:\ComboFix.txt
Note:
Do not mouse click ComboFix's window while it's running. That may cause it to stall


Note: If you have difficulty properly disabling your protective programs, refer to this link --> http://www.bleepingcomputer.com/forums/topic114351.html
