After a visit to the DriveSentry website today, I'm concerned that there does not appear to be an upgrade path short of buying the program again at the new increased price. I only purchased DriveSentry 18.104.22.168 two months ago and now it looks as though I may have to pay the full price again in order to upgrade to the latest version. If DriveSentry intend to use this as their pricing model, this could work out a lot more expensive than an annual subscription, especially if they release frequent updates to the program, which have to be repurchased each time. I'm also concerned that there no longer appears to be a trial available, as I imagine this could discourage a number of potential customers. For a program that has a community advisor component, limiting the potential user base by not offering either a free version or a free trial might not be the most sensible thing to do. IMHO this is where Prevx, for example, are smart because, by allowing Prevx 3.0 to be used free of charge, they are able to gather statistics from a much wider user base than just those users with paid licenses. That way everybody wins: licensed users (like me) get the benefit of the increased accuracy of the heuristic and behavioural analysis that results from having a large user base, and non-paying users get the benefit of some additional free monitoring software. I hope that all of this is simply an error on the part of DriveSentry in updating their website, and that both these concerns will be addressed shortly. Otherwise, it's goodbye DriveSentry and back to Avira AntiVir for me.
