I am running WIndows 7 Home Pre SP1.
It appears that I cannot run any 32 bit programs out of Programs Files (x86) - programs such as notepad and wordpad do run.
64 bit programs out of Program Files seem to run ok.
I cannot install any programs.
System restore and repair did not fix the problem.
I ran Kaspersky Rescue disk, it did find and remove a couple of viruses, but did not fix the issue.
The only file in quarantine is an Exploit Urntone.G
The security settings on the folder Program Files (x86) did not appear to be correct, so I changed them to match Program Files.
Any suggestions would be helpful!
