Have you ever encountered such issues like below?
"I turned on my laptop. I opened Google Chrome, and a red message appeared claiming that I had a trojan horse. It gave me this number to call: 1888-386-0715.
I did so, and I explained the situation to the man on the other end. He had an Indian accent. He told me to press flag+r, then type "iexplore www.123rescue.com" into the subsequent Run window. It brought me to a website, and the man gave me a code to type into the window. I did so, and a download appeared. After downloading and giving him access to my computer, the man was able to control my computer remotely. He asked me about programs on my desktop, about my security system, etc. He then brought up a text document and typed in a list of tech support plans starting at $199...."
