have to use "run as" to open files....

[lindsay]

Hi,,,hope you can help. I have the following problems in
xp home following downloading the latest ms upgrades and
downloading a freeware virus tool.

(1) am now missing the services.exe file...do i need
it....how do i restore it if i do?
(2) when trying to open .exe files. or opening desktop
icons, i get a "you do not have permission" error. In most
cases i can fix thgis by right clicking....clicking run
as..and clicking off the protection tab. How do i prevent
this?
(3) even when i do this....for some .exe's (not all) i am
told that the file cannot be found (although it has just
been downloaded\appears in explorer etc).

It sounds to me as if what you call the latest MS security and
third party virus tool might not be what you thought.
Part of your issue could be explained if the path environment
variable was messed up, but the permissions issues that you
can side-step with us of RunAs seem to indicate something
did larger scale changes to your system.
