I was recently infected by the Trojan Vundo virus and although it appears that I've been able to remove it my system now shows the following errors on start-up: 1) RUNDLL, ERROR LOADING wvvstt.dll, The specific model could not be found. 2) RUNDLL, ERROR LOADING Yaxvsq.dll, The specific model could not be found. and 3) RUNDLL, ERROR LOADING gededd.dll, The specific model could not be found. How do I repair this?

One thing you don't do

Since those dlls are likely the infected items you would not reinstall those files. But your post is too light on details. For example if you can boot and get to the desktop you could use HIJACKTHIS to fix those items.

I Do It This Way...
by Grif Thomas Forum moderator / November 2, 2010 2:44 AM PDT

If you can download the tools below on your current computer, and get them to work, then fine, but frequently the problem malware prevents the programs from running correctly. If that's the case, then download ALL of the tools below on a friend or family member's, CLEAN computer and copy them to a CD or flash drive, then transfer them to the problem machine.

First, after transferring it to the problem machine, run the following tool to help allow the removal programs below to run. (courtesy of Grinler at BleepingComputer.com)
There are 3 different versions. If one of them won't run then try to run the other one. Be patient.... as a black window should open, then close after finding all the background programs.
Vista and Win7 users need to right click and choose Run as Admin
You only need to get one of them to run, not all of them.

Rkill.exe

Rkill.com
http://download.bleepingcomputer.com/grinler/rkill.com

Rkill.scr
http://download.bleepingcomputer.com/grinler/rkill.scr

_____________________

IMMEDIATELY after running the "Rkill" tool above, run/install the Malwarebytes and SuperAntispyware installer and update files from the links below which you've also copied to a CD or flash drive, and transfered to the problem machine. Do NOT restart the computer after running Rkill.

Once downloaded and before transferring Malwarebytes and SuperAntispyware to the problem machine, rename the program installer "mbam-setup.exe" file to something else like "Gogetum.exe", then copy the installer file and the update file to a CD or flash drive.. Transfer the file to the problem machine, then install the "Gogetum.exe" file, then run the update to get the program current.. After that, run a full system scan and delete anything it finds.

Malwarebytes Installer Download Link (Clicking on the links below will immediately start the download dialogue window.)
http://www.besttechie.net/tools/mbam-setup.exe

Malwarebytes Manual Updater link
http://data.mbamupdates.com/tools/mbam-rules.exe

Next, install and run a full system scan with the SuperAntispyware program and the manual updater from the links below. As before, you may need to rename the installer file to get the program to install.:

SuperAntispyware
http://www.superantispyware.com/

SuperAntispyware Manual Updater
http://www.superantispyware.com/definitions.html
____________

In a few situations, in order for the program to run, it was also necessary to rename the main "mbam.exe" file also after installing it.. It resides in the C:\Programs Files\Malwarebytes Antimalware folder....
_____________________

And after that, if everything's fine by you can't connect to the internet, then follow the procedures below to check your network "proxy" settings.

Open Internet Explorer and go to Tools-Internet Options-Connection Tab. Click on the LAN settings button. IF there is a check mark next to "Use a proxy server for your LAN", uncheck it. Click OK. Then OK, again.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
