The module C:\programdata\rfxsuas.dat failed to load ...

  LisaDerbyshire 17:00 30 Aug 2014

Hi, Whenever I turn on my laptop I get the following message .. 'The module C:\programdata\rfxsuas.dat failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files. The specified module could not be found.'

Also when I had to disable internet explorer because it was opening new pages with the message that the browsing session had closed unexpectedly, even when I wasn't using it. I'm using windows 8.1 pro

Any help in how to fix these issues would be greatly appreciated Thanks :)

How long since this started

have win 8 loaded an update recently?

have you installed any programs recently?

could stem from from the August update problems / malware / bad install.

  1. scan for malware and virus

    if no different

  2. type sfc /scannow in the Search Box and let windows find and replace any missing or corrupt windows files.

    if no different

  3. Do a start up repair from your disk media or F* for the Advance tools menu.

Hi , Its on 8.1 I think that is the newest update I've scanned for malware and virus but it didn't find anything and I tried to restore it back to an earlier point in time but it still happens The only thing I have recently installed was firefox but have since uninstalled it and tried the virus scan again I have just done the sfc/scannow thing if this makes no difference how do I do Number 3? Thanks

I think you may have had something nasty which your AV has caught and deleted but left the rfxsuas.dat file in c:\programdata

I have 8.1 but nothing like that exists in programdata.

Suggest you delete rfxsuas file to the recyclebin.

if the machine works fine without it then empty the recyclebin.

I did the sfc/scannow and got this message Windows Resource Protection found corrupt files but was unable to fix some of them.

I searched for the rfxsuas.dat file in programdata but it wasn't there

I found a reference in a "MD 5 lookup" table. Seems to involve some form of encryption. It may be worth running ADWCleaner (free) see


And Malawarebytes (if you have it, if not here it is


  john bunyan 17:06 31 Aug 2014

PS I assume you do not have encrypted folders?

the rfxsuas.dat is there. Should I disable or delete it ?

  Fruit Bat /\0/\ 18:43 31 Aug 2014

Great we now know its a regserver problem. I still think its an old nasty not removed properly.

Click on the HKCU:Run rfxsuas Microsoft Corporation regsvr32.exe "C:\ProgramData\rfxsuas.dat and select disable.

That should sort the problem.

However you have a lot of programs running at start up that must really be slowing down your laptop.

Do you use all the Toshiba programs? (I certainly don't on my Toshiba laptop)
