Files encrypted and access denied.

@Kees
- (1) My files are encrypted( right click->prop->advanced->encrypt content to secure data is enabled) when I try to uncheck or decrypt it asks for admin privileges, which I have but cant regulate.
-(2) Using Linux to recover my files so that I can reinstall windows by formatting PC.
-(3) I know encrypting files are useless unless u know password or something but friend these files are imp to me and as mentioned I didn't encrypted them.

@Bob: "association has been lost." means, can you guide something about this.
I will put some files asap.

1. What do you mean by "regulate"?
2. Linux won't help to decrypt files. Only to copy them to copy them to another device, where they stay useless.
3. If you didn't, maybe malware did. That's why you need a backup.

I don't think this is about file associations. But we'll know for sure if you made such a file available for us in Dropbox or such a file sharing service.

By regulate I meant apply i.e I am admin but cant apply the changes. Always gets "error applying attributes" and access denied.
Scanned for malwares and viruses but no infections found(used AVG)
Could the certificate installation be the cause of problem.

And block such changes. When this happens I find myself returning to a pristine system. All Microsoft. Then I am sure the malware (which is not detected by AVG!!!) and these suites are not "protecting" against those changes.

To scan for malware you may be new to this area but there is no single solution to find and remove malware. Grif shares a list of tools at http://forums.cnet.com/7726-6122_102-5509131.html?tag=posts;msg5509131

So at this poing I'm thinking 2 things.
1. Get rid of the protection and try again.
2. Scan with Grif's tools, clean off what it finds and try again.

But before all that, backup the drive to some external. I use Clonezilla but your choice on that.

I will surely try this and post the scan results soon.

and choose the program they normally open with and get access to them that way? For choice of programs, hold the Shift key and then do the right clk, that will let you find the program you'd like to try if it's not the default one anymore. It may be the file association to particular program has changed by accident. Are all the files you can't access of the same type?

The files are images, text docs and videos. So not same types of files.
I think shift thing not gonna help.

And recovering these after a format does cost a little. I think http://www.lostpassword.com does this work.

Microsoft, no, and again no does not help you as they, well, let's just say they are not going to help folk decrypt files unless you are NSA, CIA, FBI, DOJ, etc.

What is this "regulate"?
Bob

Yes I didn't encrypted these files. Never ever. No I have only one User account i.e mine and never changed username.

But I am getting to think now, that my computer is taking some other user as the owner of these particular files only.
I can encrypt or decrypt any file on my hard disk other than these files.

Yes I had access to these files, I regularly maintain these files and were not encrypted. No not all my data is encrypted, the files that got affected were mostly on my desktop and few other files in other drives(other than C drive).

probably nothing will.

I suspect maybe some electrical event, maybe excess ripple from the power source, or hard drive data corruption on the files affected in some way.

If you can download a Linux distro as ISO, burn the "Image" to disc, and then boot to it, you can use that to reclaim the files. You may already have some boot rescue disc there you can do the same with. Linux pays no attention to Windows permissons and will allow you to copy those files to a FAT32 formatted drive which will strip off the permissions from an NTFS formatted drive. A thumbdrive (flashdrive) is good for this since most are FAT32. You can then boot back into windows, copy the files from the flashdrive or FAT32 partition on your harddrive if you have such, into your personal folders (My Documents) and they will become YOUR files again. As for them being encrypted, if that's the case, at least you will have access to them.

I cant take the electrical event to be true as only few files are affected.
I am already having dual boot(Windows+Linux). Also used Linux live CD but always get access denied or not appropriate permissions.
Also as already discussed there is no point of copying encrypted file unless you are user or authenticated person.


Please any one can suggest something else.

I read the link you posted and also tried AxCrypt and some other Encryption/Decryption tools, but got same error cannot perform the actions as access is denied or user not authorized.
