Like most of you, I was galvanised to register to post after reading the news.
My 3 PCs come with NIS preinstalled. I removed them sometime ago because it let in trojans (3 nos.) into one of my PC. I managed to install Avast! to remove the trojans and there was no looking back since.
If you have NIS, do the same and get rid of this crap.
I have Spybot S & D, Zonealarm, Ad Aware and Avast on my systems now.
Keep up the good work Spybot team.
