I had some viruses attack my computer before i downloaded norton and after doing the usual scans there were still some infecte programs i just cant get rid of on my computer. when i try to run the power eraser i always get an error stating; "Norton Power Eraser cannot scan windows 8 from a previou version of windows. Error code: 0x80041007,n44,n66. Any help would be greatly appreciated.I dont think my little nextbook can't handle this much longer.
