Network connections blocked

[sersistemi]

Hi, I have this problem from 2 days till now on some computers. I have some kind of virus that blocks every network connections. It infects the file tcp.sys and disables the avast resident protection also. It seems that it infects only Windows XP. It doesn't work in safe mode also. Do you have any solution?
