Trojan-gen removal

  1. Hello All,

    I recently came across three infected files on my computer after a few boot-time scans with Avast. One was in my cygwin /bin/ directory called "xmhtml.exe.". I was able to successfully move this one to the virus chest. I never use any application with that name, so it's not a big deal. However, the other two are a little more difficult to deal with.
    2.) c:\windows\temp\unp31070.tmp: I attempted to repair this one, but I received an "Error: the system cannot find the file specified (2)." A third scan (not boot-time) did not find this file. I suppose it is possible I accidentally deleted it, but that error seemed somewhat suspicious.
    3.) c:\system volume information\_restore\{...}\A0092346.exe: I attempted to repair this one, but it would not. I do not know what to do with this file. I have not attempted to move it to the "virus chest." Should I?

    Attached are the logs to the 8 step process listed on the webpage <>. I have not had any strange symptoms, but I went ahead with the assumption that there may be malware on my computer. The spyware/malware software showed no infections. I don't know how to read a Hijackthis report.

    Thanks for any help you can give.

    All the Best,

    c:\system volume information folder contains your restore point files, so we'll simply reset it little bit later.

    Please download ComboFix from Here or Here to your Desktop.

    **Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**
    1. Please, never rename Combofix unless instructed.
    2. Close any open browsers.
    3. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
      • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
      • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
      NOTE1. If Combofix asks you to install Recovery Console, please allow it.
      NOTE 2. If Combofix asks you to update the program, always do so.
      • Close any open browsers.
      • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
      • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
      • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
    4. Double click on combofix.exe & follow the prompts.
    5. When finished, it will produce a report for you.
    6. Please post the "C:\ComboFix.txt" along with a new HijackThis log for further review.
    **Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

    Make sure, you re-enable your security programs, when you're done with Combofix.

    DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!
