I'll just post what I said in another thread on the topic. I just changed the vendor names.
Well to be fair nothing is ever perfect. Despite the fact that people say that nothing is 100% perfect, it still kinda fascinates me when people act surprised when a product missed something, or failed a test. I'm not making excuses for Eset, personally I still think it's a great product, with very good protection, however, no matter what you use, you still always need to practice basic security 101. When it comes to ransomware, the only and I mean the ONLY 100% guaranteed protection from any type of ransomware is to simply backup. It's the only guaranteed protection against this type of thing. Look at Wanacry and how it got past so many products initially, what about the new Asus security fiasco?
Over the last 4-5 months I've seen various tests posted here, from all sorts of products and them missing stuff. All this does is reinforce the point that every product can miss malware and every product can fail at some point. IMHO we need to stop looking for something that will offer 100% protection every time, it's not available, nor will it ever be. At the end of the day, use which ever program you like most and be sure to practice good security hygiene and chances are you will be more than fine.
