love win7, but security?

i know, thats why i'm trying to sort anti virus

well... yeah... kinda...
on my netbook which i started using win7 about 5 weeks ago i was running avg free trial, which has now run out and im trying trend microsystems free trial.
on my main (desk based) laptop im now running avg's trial as ive only just installed win7.
i figured if win7 worked alright for a month on my netbook it was worth a try on the big'un. so far so good. there are a few driver issues on my big sony still, but it's early days.
still a bit disapointed that there isnt microsoft coverage in the uk for anti-virus yet, but hey-ho. i'm sure its not far behind. i guess it gives the other companies a chance to get some customers too. i think over the last 5 years i've moved much more heavily into complete microsoft integration. for me its almost a one stop shop these days, with office live, calander and windows mobile all moving closer together. i use the lot
