Hello again.

I have done what Tashi said to me; I have tryed to scan with D.D.S. and I have waited not 3 minutes, which the black screen said to me, but more than half an hour, but... nothing - a logfile/report does not open; it seems that the infection prevents DDS from running. I can not close the black screen.
It seems that is a severe infection here.
The problem is again described below, in case that is another analyst who didn't read my previous post.
Another thing: concernes "Please do not use a usb/external hard drive that has been connected to the infected machine to transfer media", is too late - I didn't knew - so, now I have an USB stick possibly infected; but for now, please help me with the computer and then...will see.
Of course, I have done all that Tashi told me, Erunt and all...

Thank you,
Spandau
