Post by: Laurenwgate on August 08, 2010, 04:28:50 AM
hi all of a sudden this has started on my computer

First of all, I get a bubble type pop up in the bottom right hand corner. "Windows Security Alert - Application cannot be executed. The file wuauclt.exe is infected. Do you want to activate your antivirus software now?"

Then I get a message in the middle of my screen. "Spyware Alert! - Your computer is infected by spware - 34 serious threats have been found while scanning your files and registry. Is is strongly recommended that you disinfect your computer and activate Realtime secure protection against future intrusions." It then gives me options to "Activate Your antivirus software or Stay Unprotected"

Next is a message similar to the second, but in the bottom right again. "Infiltration Alert - Your computer is being attacked by an Internet Virus. It could be a password-stealing attack, a trojan - dropper or similar.

i have looked through and tried all options on the net but nothing has helped, i cant open up any programs & cant get on the internet noting seems to work & to get on here i have had to use separate computer

Hello and welcome to Computer Hope Forum. My name is Dave. I will be helping you out with your particular problem on your computer. I am working under the guidance of one of the specialist of this forum so it may take a bit longer to process your logs.

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.

Please start your computer in Safe Mode with NetWorking and run the MBAM program. Reboot in Normal Mode and try to run the other programs.
How to start in Safe Mode (http://www.computerhope.com/issues/chsafe.htm#03)

(http://img233.imageshack.us/img233/7729/mbamicontw5.gif) Please download Malwarebytes Anti-Malware from here (http://www.malwarebytes.org/mbam/program/mbam-setup.exe).

Double Click mbam-setup.exe to install the application.
Extra Note:

If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately.

=====================================

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 4 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 (http://download.bleepingcomputer.com/grinler/rkill.exe)

* Rkill.scr (http://download.bleepingcomputer.com/grinler/rkill.scr)
* Rkill.pif (http://download.bleepingcomputer.com/grinler/rkill.pif)

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