You mean with a virus scanner? Do scanners not usually scan desktop?

It's probably not feasible to install programs in the user space rather than root (or is it?) but there are a lot of config, ini and xml files associated with root-installed programs within "home" space that could cause havoc if a script with a virus in it were installed there.
