Hi, sorry I forgot to give you a reply.

So what should you do now? To call some PC services to take a look this computer, this may be the best choise.

From here (via forum), I can’t assist you but someone can take a look and try to preform some fixes (re-writing of MBR & Boot, or to preform the windows repair …etc).

For example could I put my hard drive in an external hard drive enclosure and try to access it from another healthy computer?

Yes, but in that case you need to make shure that this healty computer have the active AntiVirus and MCShield installed.
