They had the ability to freeze my home computer until I purchased their software.  At the time, I had a work project due and was trying to finish before the deadline.  The message stated that my computer had many problems so I went along with it.  Provided a credit card number and then everything was back to normal.  A few weeks later, the same credit card number was compromised with a $600 purchase at a Dallas Best Buy.  This seems very ironic to me. 

Also, after I made the purchase, I recieved an email with all the information about my purchase - registration numbers, premium support phone nuumbers and instructions.  I was only charged $79.95 versus the $99.99 that others are indicating.
