Only problem with AVG is that it requires a reboot to update the virus defs. I had a bit of trouble getting the update to work with ZoneAlarm, but the big problem is that my computer is 24/7, so I have to reboot it specifically for AVG. Even so, I wouldn't switch, and I'll buy it the day they stop offering a freebie. In my opinion, using MS "anti-" spyware makes about as much sense as expecting the local thieves to protect your house if you pay them or having a convicted burglar provide the locks. You can be sure MS AS Beta doesn't prevent THEM from putting spyware on your computer. No thanks. I use AdAware and SpyBot. M
