Access Denied to C Drive Windows 7

When I try and open any programs i am getting an access denied error.  If I try and go to computer and click on the C drive it won't let me view the content.

When i am in safe mode i can view all subfolders of the C drive except the actual root.

Any ideas?

I reckon you have a virus. has this been happening for a while? maybe try and recover from the last recovery point.

if that works, make sure you have an antivirus package installed. also install malware Bytes antimalware.

Yeah that was maybe going to be my next step.  Tried a system restore back to earlier this week but no luck.

Think combofix or malwarebytes are the best to run on it?

In your shoes, I would first perform a full scan with your installed antivirus software.  After that, I would run RogueKiller followed immediately by Malwarebytes.

Won't even let me install anything bc it tries to write files to that drive.

If that's the case, it might be wise to start off by utilizing your pre-installed security/antivirus software and perform a full scan.

if no pc available, use Kaspersky cd to scan it  http://support.kaspersky.com/viruses/rescuedisk

Do you get the denial messages in Safe Mode as well?

I would be curious to see if you could produce an .arn file from this util.....

In the options above, please uncheck "Hide MS and Windows entries"..... Attach it here....
