Unauthorized changes?

[cba321]

Every time I turn on my laptop, my trend micro security records (and blocks) an unathorized change attempt.

Type: API event
Detected resource/process ID: NTUserSetWindowsHookEx
Infected File: C:/Program Files/Dell/MediaDirect/PCMService.exe
Policy Violate: Program Library Injection
Action Taken: Deny

What is going on and what course of action should I take? Should I just delete the infected file (if so how?)?

I've run spysweeper, superantispyware, malwarebytes, trend micro scan and none detect any malware/spyware at the moment.

Right click the file and go to properties. If read only is chekced then uncheck it. See if that works then. Otherwise if read-only is not checked than its a virus, then try uninstalling the program. If that doesn't work delete the file.
