When first installed you have to work with it a bit to set up a lot of "trusted zones" or else it stops most executables from running.
Once you get the .exe files for your applications all set up as trusted zones, then after that Kaspersky is totally deadly to anything else.
It automatically updates itself with new .dat files every hour.
I have used both and to be honest when I installed Bitedefender it actually picked up a virus that Kaspersky did not(it may have been a false alarm ,but I did tell Bitdefender to remove it).
The new Bitdefender 10 uses a lot less resources then the older Bitdefender 9 version,to be honest both anti-virus programs(Kaspersky and Bit) are both excellent,Kaspersky is regarded as the best,however Bitdefender is an excellent AV program in its own right with hourly updates too.
IMHO can't go wrong with either. Do note I'm talking about the paid versions.
