Programs won't open, including Regedit, CMD etc

[Upy]

Hi,

I am new to this and hope someone can help me.

PC: Dell Vostro 200 Intel Core2 Duo CPU E4600 @ 2.4GHz
OS: XP Pro Version 2002 sp3

My problem is as follows...

When I try opening programs like Sage 50, nothing happens and I don't even get an error message.

I get the same response trying to open Regedit and Command Prompt.

I ran my virus checker (AVG) and Malwarebytes, neither found anything. However it will not let me update these or any other virus/malware/spyware tools.

As you can probably tell I am not very technical. Can anyone help me with this please?

Thanks
Upy

Welcome to Major Geeks!

Your problems may or may not be malware. Running the below should help us find out.

Please follow the instructions in the READ & RUN ME FIRST link given futher down and attach the requested logs when you finish these instructions.

• If you have problems where no tools seem to run, please try following the steps given in the below and then continue on no matter what you find. You only need to try the TDSSserv steps if having problems getting scans in the Read & Run Me First.
  • TDSSserv Non-Plug & Play Driver Disable
• If something does not run, write down the info to explain to us later but keep on going.
• Do not assume that because one step does not work that they all will not.

READ & RUN ME FIRST. Malware Removal Guide

• After completing the READ & RUN ME and attaching your logs, make sure that you tell us what problems still remain ( if any still do )!

Helpful Notes:

1. If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode, you can run the steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:
   • Starting your computer in Safe mode
2. If you have problems downloading on the problem PC, download the tools and the manual updates for SUPERAntiSpyware, Malwarebytes and Spybot ( links are given in the READ & RUN ME) onto another PC and then burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.
3. To avoid additional delay in getting a response, it is strongly advised that after completing the READ & RUN ME you also read this sticky:
   • Don't Bump! It Only Hurts You!!!

Any additional post is a bump which will add more delay. Once you attach the logs, your thread will be in the work queue and as stated our system works the oldest threads FIRST.
