iYogi

I was trying to call what I thought would be McAfee Internet Security and then this company representative of iYOGI had me connect my computer to his so he could find out why McAfee cut short my subscription to their internet security. He went through all kinds of instructions to connect my computer to his, then after a few moments he said my computer was full of things that needed to be cleaned out. He said it would cost almost $200.00 to do this for one full year subscription. I could use it as many times as I needed to throughout the year. I told him no, then he pyut the pressure on, and I said no many times, he finally almost gave up. He said his name was Kevin and the number I called was [protected]. He left a search page on the Internet Explorer that I can't seem to get off. Everytime I click on Internet Explorer, it shows up first on my screen. Then a few days later another guy called pressuring me to get this same setup, but the price was down to $49.95. It took me awhile to get rid of him. I think his name is Ka' Ran. I finally got rid of him. I would like to get this search page, iYOGI, off my computer. I dare not call them back as I know they will harrass me .
Thank you
