Simple Virus Problem!!
And this virus is an open source virus.

If you open MS32DLL.dll.vbs in notepad and i you can read VBScript, you have the source....
Anyways, you can remove it by doing the following:
>>Ctrl+Alt+Del to bring up the task manager and End all instances of wscript.exe, if exist... Also kill MS32DLL.dll.vbs if found..
>>Start>Run>CMD.exe and then type
del c:\MS32DLL.dll.vbs
del c:\autorun.inf
>>Repeat the above step for each and every drive you have got...
i.e.
del d:\MS32DLL.dll.vbs
del d:\autorun.inf
del e:\MS32DLL.dll.vbs
del e:\autorun.inf
and so on....
>>Now, open Start>Run>msconfig and under start-up, uncheck MS32DLL.dll.vbs or wsscript if found....
>>Now search your c:\windows for MS32DLL.dll.vbs. It is likely to be found in c:\windows\ or c:\windows\system32. Delete it.
>>Now, update your antivirus.... Avast should do fine.. Make sure the definitions are updated....
>>Also, your USB flashdrives may also be infected, so insert them only when antivirus is enabled...
If you insert your flash drive, you may get the virus again. If you do, follow the same steps again, with your flash drive inserted. Delete autorun and MS32DLL.dll.vbs files from your flash drive too....
Now reboot and virus should be gone...
