This is my sons Windows XP Home Edition computer. He cannot launch any programs without being prompted to locate the file to "open" the exe file.

His firewall is disabled. Going into Control Panel, when you try to launch the Firewall CP, it says it cant find rundll32.exe This is a fairly common problem right now for other stuff, too.

AVG identifies one infection - Trojan Horse Fake.AFP which it has quarantined. After rebooting, trying to launch AVG also makes me find the EXE to launch it.

Ran HiJackThis, and I am attaching the log.

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up.

No one is ignored here.

To help Bleeping Computer better assist you please perform the following steps:

Posted Image If you still need help, I would like you to post a Reply to this topic (click the "Add Reply" button in the lower right hand of this page). In that reply, please include the following information:

  • If you have not done so already, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • A new DDS and GMER log. For your convenience, you will find the instructions for generating these logs repeated at the bottom of this post.
    • Please do this even if you have previously posted logs for us.
    • If you were unable to produce the logs originally please try once more.
    • If you are unable to create a log please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.
    • If you are unsure about any of these characteristics just post what you can and we will guide you.

***************************************************

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice


Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!

Problem - launching any executable pops up a dialog asking me to select the program to use to open the executable. Its as if the file associations have been removed from the computer. However, even after selecting an exe to launch the exe, future launches of that same exe still pop up the selection dialog box.

I have the original disks W XP Home Edition.

I ran an AVG virus scan before posting to Bleeping Computer, and it did find a Trojan Horse Fake.AFP.

GMER and DDS logs are attached.

OK. All Done. Worked great. Malware Bytes did pick up a few items (log attached). Programs running normally again. Updated a variety of things:
1) Firefox to 6.0
2) AVG definitions
3) Spyware Blaster
4) Spybot S&D
5) Adobe Reader and Adobe Flash Player plug in for Firefox
6) Re-enabled the firewall.

Only thing now is that I have the little red shield with the X in the middle in the system tray, saying it cannot turn on Automatic Updates, even tho the Auto Updates in the control panel are enabled.

Ok. Figured out Windows update issue. Had to regsvr32 the wuau dll. All was well after that. Machine is fully patched with AVG, Windows, Java, Spybot and Spyware Blaster.

Auto-updates set up for Windows, Java and AVG.

Thanks for your help. Could not have done it without your helpful notes.
