Probably know less than 99% of the people on here about the computer although i usually buy one a year. I have two notebooks at the office and one at home. Up until two years ago was constantly having virus's and everything else out there that was a detriment to my machines.I took them to a tech that wasrecommended by my computer mfg and they installed Computer Associates. My problems went to zero. I still have to buy one here and there but it is usually a hardware problem.When i was there last week, the tech told me that they no longer used CA ,even thought it was still great, they now strongly recommend Kaspersky. They said it was heads and tails above all the rest and was not that expensive. They thought 49.00.I I still had to buy a new computer because my lcd lite went out and it was cheaper to buy a new one and i went ahead and reinstalled Ca only because i have four months leftn my subscription, then it will be kaspersky.
