Hi @Usernameissues,
You got me wondering. I found the privacy policy
here. I think it's saying they will use data for their own purposes - to fulfill their obligations to the user and for internal marketing. I didn't see mention of selling or sharing data to or with third parties. And there's an opt-out mechanism even for that.
I use the free version, and there is no need to give an email address. One only has to skip that step each time the program's interface is accessed - a small price to pay for a great prog, IME. BTW, the popups, which come far too often, can be totally stopped by turning off "Panda News" in the Settings. (If they would moderate the popups and make them more informative, I would leave them on, and I've told them so. They need to eat, I understand. I suspect they're not strong on the marketing end.)
Panda is located in Spain, and that may curtail their privacy-related exploits more than being US-based would. But I could be wrong on that. I think AVG is in Europe too, for that matter.
And of course, privacy policy can change at any time, and since I have Panda News turned off that puts me back to relying on hearing about it through the grapevine, as I previously described. But I'm fairly comfortable with that arrangement. Ultimately it's up to my end users to research and decide which programs they want to use. I just do the best I can.
As for MSE, I gave up on it about a year ago when it began to commandeer high CPU levels. Many of my machines are netbooks or value-level laptops, and MSE was killing them. I was delighted to find Panda, and have remained very happy with it. There was one big update problem Panda had, with major fallout, but anyone can make a mistake. I suspect that most of the people here who still recommend MSE are on more powerful machines. And it consistently scores low on effectiveness.
BW,
Paul
