I get a message on boot saying "Windows cannot find C:/windows/system32/drivers/nVIDIA/dll/rundll.exe", then I get another dialog box saying it could not load or find the same file from the registry. What gives?

Hi there!

There is a potential that you have a trojan on your system. I only say this because the following are symptoms of Trojan/Zapchas-DG

When Troj/Zapchas-DG is installed the following files are created:

\win.ini
\drivers\nVIDIA\dll\control.ini
\drivers\nVIDIA\dll\fullname.txt
\drivers\nVIDIA\dll\hex.exe
\drivers\nVIDIA\dll\ident.txt
\drivers\nVIDIA\dll\mirc.gid
\drivers\nVIDIA\dll\mirc.ini
\drivers\nVIDIA\dll\nicks.txt
\drivers\nVIDIA\dll\perform.ini
\drivers\nVIDIA\dll\regedit
\drivers\nVIDIA\dll\remote.ini
\drivers\nVIDIA\dll\rundll.exe
\drivers\nVIDIA\dll\script.ini
\drivers\nVIDIA\dll\servers.txt
\drivers\nVIDIA\dll\users.ini


Please do the following:

There seems to be an error in the registry for your graphics card. Go here:
http://www.nvidia.com/content/drivers/drivers.asp
Download the latest drivers for your card. If you have the latest drivers, I recommend reinstalling them to correct this error. First uninstall then do a clean install.
Please post back if we found the solution

Hi there karbo!

I am not trying to wrong you reply, but would like to show you some general information about how this Trojan works, by showing you a security bulletin by Sophos. Click on the more information tab to see my reference if you will please.

Hello boofie75,

Now that you have a log posted here: http://www.bleepingcomputer.com/forums/t/204959/on-boot-windows-cannot-find-nvidiadllrundllexe/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere or post new topics on this issue. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the HJT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your HJT log in the thread titled "Haven't Had A Reply In Five Days?".

To avoid confusion, I am closing this topic. Good luck with your log.
