Panda Cloud Antivirus? Good Enough for Mainstream Consumer Use?

I am starting out as a tech, and a lot of people are running expired anti-virus programs. So, I generally install a free anti-virus (generally Avast Home) for them, since I have found it a very reliable solution for most tech-illiterate people However, I was testing out Panda Cloud anti-virus today in my XP virtual machine, and it is really simple to use! I messed around with it a bit, and it seems it has good detection, but I was wondering what you guys thought of it, before I install it on customer's machines? Any comments?
