McAfee Security Unauthorized Automatic Renewal??? Internet

I recieved an e-mail yesterday from McAfee saying that they had renewed my software automatically...through my Paypal account...and also recieved an e-mail from Paypal saying that my account had been charged $89.99 for McAfee Security. WTH?? 

First off, I purchased my grandchildren laptops for Christmas, and purchased anti-virus software from McAfee for those computers, a one year subscription. After the first month, my grandchildren kept getting pop-ups saying that the subscription had expired.  I also kept getting e-mails saying I needed to renew the subscription, that it expires in May 2011...I did not respond to them, as I did not intend to renew if it was going to be only for  6 months, instead of the year that I paid for.

I paid for this through Paypal, I DID NOT agree to an auto renewal plan. I NEVER do this! 
I immediately called Paypal, told them not to pay it and filed a "disputed transaction" claim, I called McAfee and basically told them off too. I called my bank to tell them about this fraud on my account and they had already paid it to Paypal!  Within minutes of me getting the e-mails! My bank doesn't even work that fast for ME!
Now McAfee won't even respond to Paypal to answer this,  in the meantime, I am short $89.99 in my bank account! 
How can McAfee do this when I DID NOT sign up for Auto-renewal?  I am in the process of filing formal complaints about this also.
