In April they issued an update that accidentally targeted legitimate Windows system files, causing the updated boxes to bluescreen. Astounding enterprise-level incompetence.
Oh yeah, McAFee has given blue screen to me many times. I bought Dell laptop for me and my gf. After McAFee free one year subscription expired, we decided to move to different anti virus. Once we uninstalled McAfee, both of our laptops got blue screens and crashed. My friend also had same experience with two of his computers.
maybe they weighed their options, and found that buying the company straight for 7 billion is cheaper than suffering through more downtime caused by McAfee software.
