    If the files are encrypted already, technically deleting them off the hard drive using the standard Windows delete option would suffice. Even if somebody pulled them back up, they would be useless without the encryption key.

    To get a secure wipe of deleted files, delete them like you normally would and use a tool like CCleaner or Revo Uninstaller to wipe the free space.

    I agree with Masterchief's post and other posts on this thread which offer secure deletion methods.

    The factor is which method offers the user confidence. Personally, I would recommend one of the methods listed in Borg's post (#11). Darik's Boot and Nuke (DBAN) is a well-known program.

    Yes. If they are encrypted you can just delete them. Never in a billion years will anyone decrypt them without the key.

    EDIT however
    there are some caveats:
    The name of the file, as well as the size, may be recovered.
    If the file has been viewed or edited with an application that creates temporary copies of the content (such as Microsoft Office may), those temporary copies may still be available for undeletion on your harddisk.

    If this matters you may want to zero the free space after (use sdelete or ccleaner as mentioned before), once is enough.

    You would be better off (if you have Pro) to use bitlocker as this encrypts the whole disk rather than individual files removing these issues.

    PaulyJustin, do you mean for wiping files or for Antivirus protection?

    I mean i no longer use avast for antivirus. I was told having window defender is enough. I use to have a few antivirus programs like avast, malwarebytes and people say you only need 1 etc.

    Fair enough. Each to their own. I guess it depends on who you ask. I'm sure there would be many other people out there that would say Avast Premier or Avast Internet Security offer superior antivirus protection over Windows Defender.

    There really is little difference these days. The biggest security risk these days is PEBCAK (Person between chair and keyboard) i.e. poor use of common sense.

    Okay so for my windows 7 on my the old desktop. Should i just keep avast and malwarebytes? And thus don't enable windows defender? So if i remove these programs, then windows defender would work? I also have microsoft essentials and super antispywhere on this desktop. Which of these programs should i delete and which one to keep? On my primary laptop, i use windows defender only etc.

    Hi PaulyJustin

    In my humble opinion, if it was me, I'd be using Avast and Malwarebytes on your Windows 7 desktop. I'm assuming Microsoft would still support definition updates for Windows Defender and Microsoft Essentials for Windows 7 if you were to just use either of those, but I'm not sure about that?
