    Application cannot be executed. The file *exe is infected
    « on: February 10, 2011, 02:17:41 PM »
    Hi all,

    My PC has been infected by some serious trojan or virus. Whenever I try to open up any application, it flashes me a virus alert saying that " Application cannot be executed. The file pctsTray.exe is infected" . I'm unable to open any application from wordpad to photos.

    I google'd and searched the forum for solutions. But none of them helped. Superdave in the past has helped some guys and has been helping some other guys regarding the same error ( below are the links). But since he has mentioned that the fixes are specific to the problem and should not be used for other issues, I want to take precautions in doing the same. I would highly appreciate if someone can help me on this issue.

    Hello and welcome to Computer Hope Forum. My name is Dave. I will be helping you out with your particular problem on your computer.

    1. I will be working on your Malware issues. This may or may not solve other issues you have with your machine.
    2. The fixes are specific to your problem and should only be used for this issue on this machine.
    3. If you don't know or understand something, please don't hesitate to ask.
    4. Please DO NOT run any other tools or scans while I am helping you.
    5. It is important that you reply to this thread. Do not start a new topic.
    6. Your security programs may give warnings for some of the tools I will ask you to use. Be assured, any links I give are safe.
    7. Absence of symptoms does not mean that everything is clear.

    If you can't access the internet with your infected computer you will have to download and transfer any programs to the computer you're using now and transfer them to the infected computer with a CD-RW or a USB storage device. I prefer a CD because a storage device can get infected. If you use a storage device hold the shift key down while inserting the USB storage device for about 10 secs. You will also have to transfer the logs you receive back to the good computer using the same method until we can get the computer back on-line.

    Finally, someone who takes my advice. Good.

    Please download and run the below tool named Rkill (courtesy of BleepingComputer.com) which may help allow other programs to run.
    Save Rkill to your desktop.

    There are 3 different versions. If one of them won't run then download and try to run the other one.
     
    Vista and Win7 users need to right click Rkill and choose Run as Administrator
     

    You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

    * Rkill.exe
    * Rkill.com
    * Rkill.scr

    Once you've gotten one of them to run then try to immediately run the following.

      I downloaded all the versions of Rkill on my USB drive and tried executing the Rkill files with the " Run as administrator" option but it started throwing up the error " Application cannot be executed. The file *exe is infected ". I formatted my pen drive again, and again downloaded the softwares and tried again, but it threw the same error. Please help and advise in this situation.

      Ok. Please try this: Reboot your computer in Safe Mode. Now try to run MBAM. Reboot in Normal Mode and run MBAM again and post the log. If that works, please run the other scans and also post those logs.

        Thanks. So I rebooted the pc in Safe mode and ran MBAM. After running, MBAM, I rebooted the pc in Normal mode and tried running MBAM again,  but it started throwing up the error " Application cannot be executed. The file *exe is infected ". I tried running all version of Rkill too but they failed again.

        I want to make sure that while rebooting the pc on safe mode, we just have to run MBAM, because I did the same. I didn't run Rkill or any SuperAntiSpyware before it in safe mode. Please advise as to what should I do in this case.

        Below is the log that is generated after running MBAM in safe mode

        I am required to inform you of this.

        One or more of the identified infections is a backdoor trojan.

        This allows hackers to remotely control your computer, steal critical system information and Download and Execute files

        Read this article: Danger: Remote Access Trojans.

        If your computer was used for online banking, has credit card information or other sensitive data on it, all passwords should be changed immediately to include those used for banking, email, eBay and forums. You should consider them to be compromised. They should be changed by using a different computer and not the infected one! If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach.

        I would counsel you to disconnect this PC from the Internet immediately.

        Though the Trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of Trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

        When Should I Format, How Should I Reinstall?

        We can attempt to clean this machine but i can't guarantee that it will be 100% secure afterwards.

        Should you have any questions, please feel free to ask.

        Please let us know what you have decided to do in your next post

          Backing up files before formatting

          If you backup any files they should be scanned from a clean properly protected PC before restoring. Also be careful what scanner is used as some are very poor at detecting and even worse at protecting from this infection. Be very selective and only backup files you can not replace like text documents and personal photos.

          Do not back up to another machine! It will likely become infected. Burn to DVD/CD, a flash drive or to an external drive which has nothing else on it and which you can format should it become infected from the backups.

          I suggest running at least 3 of the below scanners on the backup files. Run the first scan then reboot before running the second then reboot after the second before running the third.
