As I search through ebay, the most popular security and antivirus software hot seller and maintain its $value are Norton, Mcafee and Kaspersky. I wonder why Trend Micro isn’t that great, Trend Micro at one time I believe was FREE antivirus and security software, then somehow now they charge as much as other companies. So I wonder if Trend Micro initially started with just a few employees doing the research and development on their software, then gradually increases its research and development on the software and start charging money. While Mcafee, Norton, Kaspersky, been around for a long time and they large company with lots of employees and their customers are coporations big companies, this is true for mcafee and norton I’m sure, KAspersky might be smaller. I noticed there are lots of antivirus and security software out there, such as Bitdefender is also good, and many other smaller one such as Malwarebytes … I think it’s better to buy from big securities companies such as mcafee, since they monitor and update research and development constantly.
