If I have posted in the wrong location, I apologise.

Running Windows XP Home edition.

As far as I know, my computer was running ok LAST NIGHT. This morning if I double click on a Desktop Icon, or an Icon in a folder, all I get is a box telling me that it is a short cut. I cannot access the Internet.  No programmes or downloads have been added to this computer in over a week. I have transferred some photographs via my NETWORK Connection.
I have tried to do a restore and cannot.
ALSO, if I do any work in a programme, say Photoshop, I cannot save the work.
I have also found that if I right click on an Icon and Explore I can run a programme but it will not let me save any changes.
Using the right click method, I have managed to run Malwarebytes SuperAntiSpyware and CCleaner - nothing found.
Any help appreciated.
Thank you,
George.Try performing a System Restore to a few days before this started.As I put in my original post, I am unable to do a Restore.Oh, sorry about that.
When you try it, what happens?I highlight Restore my computer to an earlier time then click on Next.  The button operates but nothing happens.  It will operate every time that I click on it but it never changes to the CALENDAR - even if I wait.Try doing it in Safe Mode
