I find a file (nssm.exe) and now the problem solved, I have to check this more – Ashian Dec 10 '10 at 17:23 , the problem solved when I removed this malware. – Ashian Dec 10 '10 at 19:52

Try to run without the anti-virus.

If this solves the problem, find another anti-virus.

If it doesn't, check if the problem occurs while booting in Safe mode, to determine if the problem is caused by an installed product.
