MLD, after trial, I found that you use deleting sysdm.cpl to solve the virus prompt, but then you can't view system information. Actually, you can modify sysdm.cpl to remove the virus prompt.
Open sysdm.cpl with a hex editor.
Find: 74 18 ff 76 0c 1e 57
Replace: e9 17 00 76 0c 1e 57
This can remove the prompt that the master boot information is modified.
