How to ensure a permanently delete (shift + delete) file has been deleted and is not recoverable with advanced software
Hi experts, I cleaned my harddrive using shift delete but also normal deletion and then empty the trash. I do so I can prepare to be sold on if I find a moment (and buyer).
I am told however that this actually does not remove the files but brand only as "too accessible writing." And that it takes a while - depending on how much has been marked to be deleted permanently - for these files too write.
How can I make sure all the files I want to permanently delete are not recoverable with advanced software?
How long would it take to write too say 20 GB of data?
Your feedback is very much appreciated.
Rgds,
WV
Use Google or Bing to search for 'file shredder' or 'secure erase' software which will overwrite files with random patterns of data, making them unrecoverable by most of the efforts. HOWEVER, please keep in mind that no matter what you do, away from physically destroy the hard drive, there are always ways to recover files even if these files have disappeared in a secure way. That's why U.S. Federal agencies requiring a high security have their hard drives shredded into metal fragments when they have access to computers.

How can I determine if a created PDF file has been encrypted in a unix or linux box
I'm not sure if execution of the command file on my box will tell me if a given created PDF file is encrypted and with what level of encryption. Is there a way to determine if the file is encrypted by using the Unix/Linux tools after the fact?
Thank you
Sam
It is assumed that you want to do this in UNIX command line / Shell / Terminal. There is a way that you could do that and that is to 'rolling' and build the tool with the Adobe PDF Library SDK. Datalogics, which is an Adobe partner has a port of UNIX for the Adobe PDF Library SDK which could be used to create a tool that does this for you, but there is a very big opposition involved in the price structure for the Adobe's PDF library.

The items are permanently deleted and not going is not to the trash
Someone can tell me why what I delete is permanently deleted and not going not in the trash, it started only in recent days, any help would be appreciated. Thank you.
Not being is not to change the properties of recycle bin is definitely not normal. Have you checked for viruses again?
You also have some installed system utilities that could be the cause? I remember years ago there are installation of Norton Utilities and there was an option to take control of the trash. If you have a utility like this, it could be responsible for what you see. Have you installed software in the last days? Did you changed settings recently?
An option that you can take advantage is the system restore to go back a few days before the problem started. To run system restore, click Start-> programs-> Accessories-> System Tools-> system restore. Click on the box that says show more restore points.
Good luck.

My computer has been hacked and I want to delete unwanted users who have been added
My computer has been hacked and the settings have been changed to add remote users. I am trying to remove additional users that have been added, but I don't want to delete something I need by mistake. I'm the only person who uses this computer and I don't want to share it on my network. There is a user called "SYSTEM" that should I delete also Aministrators (plural) and trusted Installer. I have to keep one of these?
Hello Debkp123,
You don't want to remove the SYSTEM account. (It probably not you would delete this account)
