It's a year since the last time we upgrade our virus definition in our computers and guess it's the time for us to change to the ESET smart security as i ma not so keen on the existing security solution software we are now using as we will need to buy a few different software for different function. Of course, this will also affect the cost of buying a few softwares and thus my boss is giving me a no sign to continue using all the different software. Since I found out that Eset smart security offer best in class computer security software, I might consider it as they received lots of compliments from their existing users. When to change? This will depend on my boss when he will approve the budget for this software.
