Explorer.exe – Bad Image
C:\PROGRA~2\SEARCH~1\Datamngr\x64\datamngr.dll is either not designed to RUN on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.

this keeps POPPING up on my laptop screen whenever i click on anything and its getting quite annoying. what can i do to stop it?What's the OS ?  XP, Vista, 7 ?

Can you recall making any software changes before this occurred ?

I would start with some anti virus scans.  Trinity rescue disc has some good ones, if you're up to burning the ISO to CD. Might want to back up your files (if possible) before running scans. 

It could be a program or service.  You can also try disabling start up apps and non-ms services.  Are you familiar with that task ?

Does the problem occur in Safe Mode ?  Restart the computer and tap F8 key until you see "advanced boot CONFIGURATION" options.  Select safe mode, LET it boot and try clicking something again.You're infected.

Follow the instructions here.

Datamngr.dll is part of iMesh (an AWFUL, spyware infested p2p tool) as well as the MediaBar malware family. hm, good call
