As a big advocate of Prevx, I guess I'll chip in here and try to provide an un-biased perspective.
I don't know how much you know about Prevx1, so I'll give a general overview and explain why I think it is much more powerful (and will continue to get stronger) than rival security products.
Basically, Prevx1 is unique. There really is no other product on the market that works in the same way.
Generic security products (Norton, McAfee, AVG, Defender, Trend, etc) are all still heavily reliant on signatures - meaning they first have to find a new infection in one of their honey-pots (robot computers that search for infections), before one of their researchers then studies the infection and create a fix. This fix is then made available as a signature update for the userbase to download. This process can take hours, days, weeks - and with some infections even months before a fix is available, in which time the entire userbase is open to attack.
Prevx1 is very different in this respect. Instead of having "honey-pots", their actual userbase becomes their detection tool. For example, if I were to browse the internet and unwittingly download/run a malicious file/script, then Prevx1 will monitor the behaviour of this script. If it breaks one of the behaviour rules (ie. unauthorised access to your address book, viotation of physical memory, editing hosts file, etc, etc) then it will immediately block this infection from running. This is good, but the best and unique difference here is that the Prevx1 agent will then communicate all information regarding this malware (all files, behaviour, hash, etc) to the central Prevx1 database, which then immediately blocks this malware from running again on any other computer with Prevx1 installed - and no need for an update. This means Prevx1 is being continually updated every second of every day, with no lag between it learning of new threats, and the userbase being completely up-to-date. Certain security vendors make a huge fan-fare over how they update their definition multiple times in a single day - but nothing can really come close to true real-time updating.
Another great advantage is that because of this model, Prevx are regularly far and away the earliest to detect and create fixes for new threats. If a bad file is detected anywhere in the world - as soon as the central database is informed, a webpage is created offering all information to the public. As written in a *recent article, Google simply cannot index this information quick enough - therefore people are becoming reliant on using the Prevx file research box on their website to check for cutting-edge new files Google isn't aware of.
The more people who download and install Prevx on their machines, the stronger the protection will become as it will be seeing more and more files and behaviour...
Ok, I tried (and probably failed) to give an unbiased view - but am amazed how little people know about how Prevx1 works. In my opinion there really is nothing else that comes close when you understand how different and fast it is in comparison.
