Hello!

 

First of all thanks for taking the time to read this!

 

I have a load of family pictures on my old windows computer which I am unable to open, a friend has had a quick look and tells me that they seem to be encrypted but he does not know how to fix the problem.

 

My files are on a system running Vista.

 

Again thanks for the time reading this.

 

Andy

 How were these files created?  Are you sure they're .JPG files?  What app are you trying to open them with?  You might want to try opening them with a different app like maybe Windows Live Photo Gallery or Irfanview.  If they are in fact encrypted, you're going to have to find out how they got that way and what the encryption key was.


Everyone with a computer should back his system up to an external hard drive regularly.  :thumbsup:

Hello wpgwpg,

 

The files are just general photos taken, on mobile phone, digital camera etc not the same source.

 

The file extension is .jpg

 

I have tried opening them on the windows computer and also on my mac using several different apps all with the same result.

 

To be honest I am not really sure how the were encrypted, how would I work this out?

 

Thanks

 

Andy

 You'd know better than me I'm afraid.  I'd ask whoever created them.  If they don't know, I don't know who would.  I suppose it's possible that whatever media they were on was subjected to some kind of extreme condition like maybe excessive heat or some kind of radiation.  Maybe you could recover some of them from the original sources?

 

Good luck.

Do you have other kinds of files on the same computer?  E.g. .doc, xls, etc.  Can you open these other file types or are they encrypted too?  I'm wondering if you are infected.  Cryptolocker (and its variants) can encrypt all your personal files and demand a ransome to have them decrypted.  Have a look at some of the topics in this sub-forum: http://www.bleepingcomputer.com/forums/f/45/general-security/
