The pc seems to have gone to a previous set point during the boot, but now she can not install software and doesn't seem to have Norton AV more

My daughter's office got fried during the last storm, even though she had a surge protector.  Obviously the power company line was bad.  The pc seems to have gone to a previous set point during the boot, but now she can not install software and doesn't seem to have Norton AV more.  When she tries to run a system restore it gets "extended attributes are incompatible."..: thank you for your help.  Debbie
