my computer is now slower than before I ran the virus scan. Ad states "use as many time as you like on as many machines as you want. I got a pop up screen while running the scan on my third devise and was told I could not use the fixit stick on anymore devices as three was the limit. no too thrilled with the fact that when I run clean computer, I get no indication as to what is being cleaned from my computer. I have no idea if you are actually cleaning anything off my computer or just running some cutesy software that makes it look like you are cleaning my computer.
