installshield setup launcher has a problem and must close

after working on a friends pc that had the win32.licum virus I cannot get
Norton started nor uninstall some other programs. when I go to launch Norton
A/V the popup window says that the access to the script is denied and when I
go to Etrust A/V it says that it is not a win32 app. when I try to uninstall
either of these I get a msg that the installshield setup launcher has a
problem and will close. I have run Recovery console and did a chkdsk /r. I
have also ran the windows XP setup Repair utility and still having problems.
I believe I have the virus out of the system, but now windows XP is all
fubar.
