I did Google for it and that was where I discovered that it was a
Vista program.
My question still is ,can I delete it.
SO where did you read that it is a Vista program? Obviously we didn't
get the same exact results as I came across this in one of them that I read:
Description: File unsecapp.exe is located in a subfolder of
C:\Windows\System32. Known file sizes on Windows XP are 16,896 bytes
(57% of all occurrence), 37,376 bytes, 37,888 bytes, 24,064 bytes.
File unsecapp.exe is a Windows core system file. The program has no
visible window. It is a trustworthy file from Microsoft. There is no
information about the maker of the file. Therefore the technical
security rating is 6% dangerous, however also read the users reviews.
So it's your call... since it's a Windows core file deleting it would be
pointless as Windows system file check would replace it when it
discovered it missing. The purpose of the program is to provide
compatibility with the operating system for older programs. Apparently
you are running a software that requires the use of this program.
