I have a strange problem with Windows 7, I cannot run any executables from the desktop or from the start menu. When I try to I receive a "These files can't be opened", your internet security settings prevented one or more files from being opened. Some guides say to access the security settings internet zone but it is completely blank.
Weirdly enough though I am able to open programs by using the "Open with" command to run it. E.g to get firefox to run I need to open a txt file and open it with firefox. Other programs I've had to run it by cmd prompt, but this would only work if I shift click and open a location in the command window. Any direct double clicking on the executables results in the above error.
Please help, I'm not sure what else I can do to fix it. My backups have been having problems so I can't restore back to a previous time before this happened.
Thanks in advance for any help.
