When the individual called (sounded like an "Oriental" speaking broken English) advising me he could get rid of a bad program I had on my computer; this was an unwanted sex site. I couldn't delete it so I agreed to his plan. Finally realized I HAD been taken and told him to cease his taking control of my computer.
He started getting nasty with me; I got nastier back and demanded he relinquish control. After he did so, I deleted all links he had added, and demanded he not call again. Over the last several months, I've received over 300 calls from the same individual-some I've answered and using vulgar language demanded he stop.
The phone calls continue; I simply don't answer anymore. Their toll free number is still listed at the bottom of my computer, however=1-888-331-8953.
