I received the iYogi phone number from QVC. I purchased their best plan for 5 years. At first they were excellant - available 24/7. They give you many icons for several tools. When I subscribed to the "password management program" they tried to break-in my bank account. Fortunately I had not entered my password information.
They also put malware and viruses on my computer then they called me, saying they were from Dell. They tried to sell me a program. Do not trust them.
