Background: 500 GB HD began to max out, determined total folders/files should be approx 250 GB. I have Bitdefender but somehow a Trojan got by but finally found with HouseCall. Now all folders indicate "folder empty" although properties show that contents are what they should be. Currently running a full system scan by Bitdefender (45% after 3 1/2 hours) but that won't solve my real problem, which is:

Just ran cmd attrib and discovered ALL files are now access denied. Is there a way to do a wholesale delete of the access denied prefix within cmd or is there another way to solve the problem?

  1. Go to folder properties and see if you have correct permissions.
  2. Open command prompt with Administrator rights.
  3. To take ownership :takeown /r /f *
    (first test this for one file by giving filename instead of *).
  4. Then to reset file permissions: icacls * /reset
-1

An "Access Denied" error message can occur for one or more of the following reasons:

1.The folder ownership has changed.

2.You do not have the appropriate permissions.

3.The file is encrypted.

More than likely the files are encrypted by the malware, you are basically screwed unless you pay them to un encrypt the files.
