Rundll error

alexalexalex

I turned my laptop on today and got a pop up saying:
"RUNDLL
error loading C:\Windows\cenmsf.dll
Access is denied"

i just closed it and carried on at first as i normally have a similar message pop up on startup but this cenmsf.dll message is popping up every 15 seconds or so.

i've had a lttle google but cant find anything on this partcular dll, anyone got any ideas or solutions as its getting pretty annoying and i cant ignore it because i end up with a dozen error messages if i dont do anything for more than a couple of minutes

thanks

Download CCleaner and scan the registry for errors. Backup when requested.

CCleaner is safe to use

What operating system is it?

alexalexalex

xp pro sp2

the laptop has been a piece of junk since i got given it to be honest, couldn't stay connected to the internet, cant update use windows updates, etc etc (thats pretty much why i was given it) i've just about managed to keep it running well enough to surf and use office programs but its not up to much else


@dogmaryxx - i tried the ccleaner but no effect, thanks though

here's the log for good measure though:

Youve also made the BIG mistake of installing 2 anti virus programs
Choose between AVG and AVIRA (Id personally recommend you keep Avira)
If you choose AVG then uninstall Avira
If you choose Avira use the 32 bit AVG removal tool
http://www.avg.com/download-tools

ADAWARE is next to useless too, id recommend uninstalling that too

here's the log for good measure though:

Malwarebytes' Anti-Malware 1.44
Database version: 3871
Windows 5.1.2600 Service Pack 2
Internet Explorer 6.0.2900.2180
.

You never UPDATED malwarebytes as I asked. We're now on Database version 3954
Please update and rescan

Then as you had/have trojans ~
Please run COMBOFIX
http://download.bleepingcomputer.com/sUBs/ComboFix.exe
Shut down your anti virus
Follow the simple instructions it gives
Post the COMPLETE log it creates here (Split into sections if need be) ~ if there are loads of 'SNAPSHOT' pages then leave them out

If it comes up with a RENAMING error then RIGHT click the exe file and RENAME and call it QWERTY (Making the complete file name 'QWERTY.exe') Or SAVE as 'QWERTY' on download
