I would be cautious about Panda for a different reason.
I frequently check out AV software to see if I want to switch. (I have three machines at home, and am more or less responsible for another few.) A few months ago, I decided to once again to try Panda. I couldn't even get it to install properly on my main - admittedly old - machine, so I decided to forget about it. I started getting email warnings that my trial copy was about to expire. Fair enough. But I kept getting promotional emails from them even well after the expiration, and even after I went through their multistage unsubscribe procedure a few times.
It is now clear that I will be on their mailing list forever. To get spammed by a well known computer security vendor is unnerving.
Good luck.
