Are Rundll32.exe, sm56hlpr.exe or NetFilter.exe viruses or malware?

Q: My Windows XP computer got a pop message about “new hardware not being found…” My son was playing WOW and no one was installing any hardware-or software on our end! Under Safe Mode, I’m reviewing startup tab items. Are any of these possible viruses or malware Rundll32.exe, sm56hlpr.exe or NetFilter.exe

    They can either be important parts of windows or junk, as junk likes to mask itself that way.

    What kind of anti-virus/anti-malware software do you have installed?


    Norton Anti-Virus which stated there were no problems or suspicious items after a full scan. Since then, I did a “recovery” process which started the computer back to its original settings. This was after doing multiple “restore to earlier dates” and none of them working. I’m now re-loading some software. When I look at the processees running in task manager, it lists
    Spysub.exe. Should this be removed?
    Thank you!


    spysub.exe is a process associated with SpySubtract from InterMute maintains a database of windows processes, which is where I got the above information.
