Can't run sfc /scannow nor Event Viewer

Under what circumstances will sfc /scannow or Event viewer be disabled and cannot be run under winXP?

These processes were not knowingly disabled nor deleted. However, they cannot be run. Why? What could have disabled them? How can they be restored without the XP CD? Will an XP Restoration CD suffice?

Thanks

 

Would it be possible or advisable to enable disabled services through the services.msc snap-in?

 

Well, here's a link that describes how to disable Windows File Protection (sfc is a part of that), you can back track to make sure it's set to be there..

Event viewer being gone seems strange, but I think it can be turned off by disabling the 'event log' service, you might want to check and make sure it's enabled.

And yes, changing service settings SHOULD be done in services.msc because it will alert you if you are about to disable something that other services depend on. Making changes through msconfig, for example, won't do that, so it's easier to mess things up.

Have you been using tweaking programs, by chance?

 

Hi Notok

Thanks for your response...

No tweaking programs involved but it is possible that these processes were screwed up in a major malware infestation in one of our computers in the workplace.

I would really like to use scannow in an attempt to restore possible missing/corrupted files but I can't seem to run it. Same with Event viewer. System restore is no longer an option as this feature was inadvertently disabled in one of the attemts to fix the problem. Would the Automated System Recovery process be useful, safe and advisable?

 

Are there any existing malware known to disable these processes? Or were these processes disabled in the cleaning process?
