There is a scam going around on the net, it comes in some way around your virus blocker it just pops up in a big red window and looks like something from your virus blocker and shows you have 22 virus on your computer and you need to click to remove. If you do not kill power to your computer when it pops up it shuts down your virus blocker and it takes hours to find it and remove It is being hidden in files and is hard to find. It is not a virus but a scam to get you to give info in order to get it removed and then they can clean you out.
Lucky for me I have a Grandson who is a computer tec and I did not click on it but it had enough time to block every thing. Took a couple hours to find and remove. Thought I would mention it in case you get one but you only have a few seconds to kill power before it goes to work.
