Do others agree with what masterchief says here?

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.
