Sorry, not a chance. RSA-1024 is well beyond what people can factor with 
readily available resources these days, which is precisely the reason why 
1024 bits is still being widely used as an RSA key size. RSA-512 is very 
feasible as a home project and would take on the order of a (few) months on 
one computer, RSA-768 is already quite a tall order and would take on the 
order of a year on 1000 computers, and RSA-1024 is maybe 1000 times harder 
than that - no one knows for sure because it has never been done yet, as far 
as is publicly known.

I'm afraid the only advice I can give you is to invest in a good backup 
solution and anti-virus software; advice which I realize is entirely belated 
under your current situation.
