Hmmm an interesting concept...
What's the most difficult thing for MS to push? (other than people to upgrade

)
Their stinkin' patches!
Thats why there are so many virus problems, because people don't patch their machines (If they'd stop integrating new crap with their bug fixes it would be nice)...
BUT... what do most people that antivirus KNOW they have to do?
UPDATE the antivirus regularly....
SO MS puts the AV updates on windowsupdate.com (of course!) a user goes there and windows update says you need all of this crap... a typical user 'yeah just give me all of it shut up' so MS gets users to update their machines for less problems and they get to throw in any "features" they want into the updates including DRM stuff...
Thoughts?
I think they have a bit more pressure on them this time red.. there firewall has a noted bug in it, their OS
IS a bug, their web browser is the swiss cheese of security... they
have to get the antivirus right.. if viruses start sliding under the covers of that thing that will push even more people away from them... and many corporations are already at the tipping point for many reasons (Licensing 6, viruses, overwhelming integration of junk into the OS etc)
