Hello GordonMacD,
Have you scanned recently for Malware? It sounds like a virus may be causing your programs to disappear. I suggest you run one or more antivirus to see if you have any viruses that
could be causing your problem.
If you don 't have antivirus installed, then I suggest you install one. Microsoft Security Essentials is a good antivirus and it is free.
Clickhere to download the most current version of Security Essentials.
Have your run any registry cleaners? They could also be the cause of problems with programs disappearing.
If your programs are gone, the only way to get them back is to reinstall them.
Please reply back with an update.
Sincerely,
Marilyn
