That’s probably a personal call, grcguy. I’m not saying it’s a bad thing, just that the way these apps work is in pretty much the same way as malware. As far as if it were sending out info, that should be easy enough to monitor, especially if you have Comodo Firewall (not to plug the product, but it does provide a high level of control over how an application is allowed to access the internet). Thus you could mnake sure that Crawler can send you the info you want (if it works by email, or whatever - I don’t know its methodology), but can’t go out wherever. I used one of their other products, Spyware Terminator, for a long time, and never saw any suspicious behavior.
It is my understanding that some years ago, Crawler put out some adware in some of their stuff, but have since “reformed” and are no longer doing so. Again, I never saw any suspicious behavior.
A friend asked me to look into parent control products for them as well, which I did. It could really kinda make you paranoid, LOL. If they’re thorough,it seems to behave like spyware/malware/keyloggers, and I thought, “why should I trust this thing?” The answer probably lies in the trustworthiness of the source, reviews, user input, and whatnot.
You want to be able to have some assurance that your kids are relatively safe on the internet; control their site access, be aware of who their “buddies” are and what info they’re foolishly handing out, etc. And you want to do so in a way that does not violate their trust, nor compromise the security of your computer and/or home by being worse than the alternative. In doing so, you have to be confident in the product and methods you’re using.
I’m not in that position as a parent yet, but it’ll be here before too long. IMO, using something that logs their keystrokes or takes screenshots and reports to me, is a little invasive, if there’s no specific reason to suspect trouble. But that’s just me. However, something that tracks website usage, and allows blocking of bad sites (or sites you don’t want your kids on, such as myspace, or whatever), is probably reasonable in this day and age. It is your job, after all, to protect them. If that reveals that they’ve found ways around security, or are intentionally makin’ a run for the border, then perhaps more stringent methods are required.
