still having problems. Installed Norton 360 V4.0, and the msascui.exe (Packed.Generic.290) virus was detected and quarantined. However, now when I attempt to open any program, I am prompted to identify the program to be used to open the program. Or, in the case of Excel and Word, clicking on the taskbar shortcuts gives an "Application not found" message. This is over my head, and I'd appreciate any assistance.
