I have a good friend who dropped his laptop off for me to look at.  It was continually re-booting after showing a quick error message.

 

The machine is an HP laptop running Windows 7.

 

I started his machine in Safe mode and ran MalwareBytes.  It cleared out a few smaller items, but both MalwareBytes and Avira reported BOO/Cidox.B in the boot sector.

 

Is there a way to remove/repair this without low-levelling the drive?  He has a bunch of photos and other business stuff on the laptop.

 

He says that the problem occurred when he opened an email from "Costco" which I'm sure was a fake.

 

I have searched the 'net and not found much info about this.

 

Any help & suggestions would be appreciated.

Unfortunately this may be a Rootkit that might have affected the MBR.

I encourage you to seek assistance from our Malware Response Team.
