Ok, to start it off i think i have had this since monday, 1/28/08
It started out as a Trojan.Vundo, i ran multiple anti-spyware/cleaners. Then i found a program called "VundoFix" it seemed to have worked, but caused 3 .dll run errors on startup. Yesterday AVG found the trojan horse generic9.aibf, it healed it, but found it again this morning.
I don't know what to do anymore.

RunDLL32.exe is a legit Windows file that loads .dll files which too can be legit or malware related.

The "Cannot find...", "Could not run..." or "Error loading..." message usually occurs when the .dll file(s) that was set to run at startup has been deleted and it becomes an orphaned registry entry. Windows is trying to load this file(s) but cannot locate it since the file was removed during an anti-virus or anti-malware scan, or the uninstall of a program. However, the associated registry entry remains and is telling Windows to load the file when you boot up.

When Windows loads, it looks for any files associated with registry entries for programs that are set to run at startup. If the file was removed but not the registry entry, Windows will display an error message. You need to remove this registry entry so Windows stops searching for the file when it loads.

To resolve this, download Autoruns, search for the related entry and then delete it.
  • Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if your not sure how to do this.)
  • Open the folder and double-click on autoruns.exe to launch it.
  • Please be patient as it scans and populates the entries.
  • When done scanning, it will say Ready at the bottom.
  • Scroll through the list and look for a startup entry related to the file(s) in the error message.
  • Right-click on the entry and choose delete.
  • Reboot your computer and see if the startup error returns.

It found it all and removed it, but I've tried to system restore around 7 times, and i get a message after it attempts to restore and restart, "System Restore did not complete successfully. Your computers files and settings were not changed. Details: An unspecified error occurred during System Restore"

Also, Windows Security Center doesn't detect my anti-virus, or windows defender anymore, but both of them are working and running.

My W-LAN signal is showing I'm not connected to the internet, although i am.

If i need to post in another sub-forum or whatever about the other problems just tell me, but i figured it all had to do with the virus since it just started doing all this when i got the virus.
Thanks.

Sometimes, the Security Center stops recognizing an antivirus or firewall program. Here is one possible solution that may work:
  • Click on Start > Run and type: services.msc
  • Press OK.
  • Click the "Extended tab" at the bottom to view all the info on your services.
  • Scroll down the list and find the service called Windows Managament Instrumentation.
  • When you find the service, double-click on it or right-click and choose "Properties".
  • In the Properties Window > General Tab that opens, click the "Stop" button.
  • From the drop-down menu next to "Startup Type", make sure its set to "Automatic".
  • Exit and return to your desktop.
  • Right click Start and choose Explore.
  • Navigate to C:\Windows\system32\wbem\repository
  • Delete or rename this subdirectory ONLY.
  • Close Windows Explorer when done and reboot your computer.
This will rebuild the deleted folder and the database. Once restarted, Windows Security Center should show the correct information and antivirus/firewall should be recoginized. See "WMI FAQs: How do I rebuild the repository?.

If System Restore is not working, check to make sure it is started and set to automatic.

Go to Start > Run and type: services.msc
  • Locate the System Restore Service and double-click it.
  • Click the "Start" button, then set the startup type in the dropdown box to "Automatic".
  • Press Apply > Ok, then reboot and try using it again.

    If its still not working, go to Start > Run and type: services.msc[list]
  • Locate the System Restore Service and double-click it.
  • Click the "Stop" button, then set the startup type in the dropdown box to "Disabled".
  • Press Apply > Ok, then reboot.
  • Open My Computer or Windows Explorer, go to Tools > Folder Options > View and check "Show hidden files and Folders", UNcheck "Hide Protected operating system Files (recommended)" and hit Apply > OK.
  • Check the "System Volume Information folder" on each drive and delete its contents (doing this removes all existing restore points).
  • Then reverse the steps where you disabled the service and restart it: Click "Start" and set set the startup type in the dropdown box to "Automatic".
If this still does not help, then follow these steps to "Reinstall System Restore".
