A friend of mine had his computer attacked with a malware program that said it would remove the malware if he paid a certain price. Anyway, I went on the internet to find a way to remove the malware; and when I clicked on a site promising to remove it, it then infected my computer, too. I had taken the bait. With both our computers infected, I called another friend that runs his own computer lab. He services, builds, and sells computers and networks world wide from a remote region in the Oregon Coast Range Mountains. He Told me about SuperAntiSpyware; and SAS cleaned those computers immediately. It not only cleaned the computers, it found trojans that I didn't know I had.
(Cyber attacks like that reminded me, in concept, to the groups of little boys in Hong Kong that used to approach us sailors and squirt something like white paint on our shoes. Down the street another group of these homeless children would approach us and offer to clean off the paint for a small price. We felt sorry for those kids, and didn't get really mad at them, just irritated. We would have given them some money anyway.)
