Very true. FYI, everyone, the best tool I've seen for dealing with the fake antivirus type viruses (if you have a program that says you need to enter your credit card to get rid of a virus, uh, use your brain...) is Malwarebytes. It doesn't do much else that I know of, but it takes out those bastards like nothing else.
The smart IT guy at work, not the ones in control also recommends Malware, and found a very nasty bug and did a "bugs be gone" with it on my work machine. I have a copy at home now.
