This is like war - the old soldiers are more likely to survive than the newer soldiers, because they have had time to learn different things. I don't know how old you are, but I saw you registered 2008, so while you are not a newbie, you may not be an old veteran either.

And of course many veterans die too. Quite often.

I won't be back to my home city until tomorrow night

So it is impossible for you to do anything to your computer now. You must first see what is awaiting in your home city. Other than that, I agree with zlurker's message. I can just wish you good luck.
