I have been doing a little unoffical test of my own with Panda Platinum and Trend Micro. I've noticed that when doing a C:\ scan, Panda scans about 160,000 files, while Trend Micro scans around 36,000. Why the big discrepency? I figure it has something to do with one scanning inside zip files and the other doesn't. But I don't have that many zip files on my computer. What else could cause this?
