I'm sure its anonymous, KSN is for researching new files so it sends it over the cloud so they can investigate it.
You got it wrong. Kaspersky relies on the home users data. This is "Free" not because they are nice to you and don't need your money but, just like with Google products or social media, because you are NOT THE CUSTOMER for them. You're a resource for mining data. A lot of people just blindly click accept in the agreements when they install software and porbably haven't noticed that Kaspersky free is also a data gathering tool for 3rd parties. If you accept one of those agreements regarding the Kaspersky Security Network (KSN) you're giving permitions to collect stats about your system, usage, installed software, websites visited and so on. Of course other free software also do that and I'm not saying it's a bad product or it shouldn't be used but just don't be naive and believe they are really nice guys that just like to give stuff away for free. Kaspersky is a BUSINESS just like Microsoft or Google but users rarely actually know what's the actual business about (i.e. how they make money) and who the real customers are.
Yep I have and it was all a waste of time. A scam in some cases. It was pure hype and nothing happened so all the hard work and preparations were for nothing. Theres dodgy codes out there all the time but the was no Y2K bug.
Have you not thought though that perhaps it is because of the hard work and preparations that occurred when we rolled over from 1999 to 2000 that nothing went wrong?. There was plenty of dodgy code out there that was fixed, I saw it first hand. :)
