I ran a virus scan on my computer this morning and it found two trojans in this particular dll file and proceeded to delete it like normal. Now, when I start up my laptop it says it failed to run that dll file because it can’t find the module. What is it, where can I find it,and is it an important dll file that I need?

This typically happens when the anti-virus program removes the files from your system but does not remove references to these files (i.e. Windows still tries to start associated programs on startup).
This may be a little bit advanced, so be careful, but generally what you want to do is this:
Start->Run
type “regedit” and press enter. This will open the Windows registry editor. Registry is where Windows keeps settings like which programs to open on startup, which programs are associated with files, etc.
First, you should make a backup of the registry:
In the left hand pane, scroll all the way to the top and find “My Computer”.
Right click on it, and choose “Export” from the menu.
Type in a name of the file like 2009.07.06.Reg.Backup and click save. Now, if anything goes wrong, you can simply double click that file, and it will restore the registry to the current state (Alternatively, you can create a System restore point – you can google on how to do that).
Now that your backup is created, choose “Edit” form the menu, and go to “Find..” (or press Ctrl+F).
Type in the name of your file and start the search. If/When it finds any entries with that file name, simply right-click on them and select “Delete”. After the entry has been deleted, press F3 key to continue searching.
I suspect you will find it in
HKEY_LOCAL_MACHINESOFTWAREMicrosoft…
and possibly several other places. Actually, Windows keeps some backup entries that it will not allow you to delete. That’s ok, just keep press F3 and attempting to delete until the end of registry has been reached (it will tell you so).
Good luck. I would strongly recommend running your virus scan again. A lot of viruses with this naming “convention” are polymorphic and will rename their DLLs. Depending on your security software, it may be hard to get rid of without manual intervention.
You must have spelled it wrong.
