Trojan Vundu, winupdate86.exe and Spyware
« on: December 17, 2009, 07:33:17 AM »
Hello! It looks like I am another victim of a Malaware/Spyware. Here are my symptoms:
- By visiting a dubious website, I noticed that my firewall detected that a lot of new programs were asking for Internet access. I declined those requests.
- I also noticed that everytime I tried to access programs like Notepad, Task Manager, I would get the following message: "application cannot be executed. The file is infected. Please activate your antivirus software".
- Moreover, everytime I tried to access www.bleepingcomputer.com or www.malaware.org, my browser would get redirected to a site that basically said "I have a virus"
- I ran HijackThis (2.0.2) and realized that \windows\system32\winupdate86.exe was one of the culprits. I cleaned that registry entry using HijackThis and deleted the file. This fixed some of the problems but the next time I rebooted, I had no internet connection and everytime I tried to install Malaware bytes, the setup program would crash. To fix that, I used System Resotre in XP to backup to a good version of the OS and that seemed to give me back the Internet access and allowed me to install Malaware Bytes.
- Next, I ran Malaware bytes which found four problems, including Trojan Vundo. I have attached the log.
- Next, I ran DDS and I have attahced DDS.txt and Attach.txt
- I have also attached the log file from GMER, gmer.txt
- I could not run ComboFix as that seems to be unavailable right now.
- My concern is that by System Restore, I disabled loading the malaware but it's still lurking on the computer. I also read that the Trojan associated with the message, "application cannot be executed. The file is infected. Please activate your antivirus software", steals financial data.
- Do you guys see anything in the logs attached? I will really appreciate any help.

Here are the logs, which were generated in this order: MBAM.txt (malwarebytes), DDS.txt, Attach.txt, GMER.txt, Hijackthis.
