My experience with no shouting

I have several non-nerdy friends and acquaintences who have called me with serious system problems (spyware, viruses, worms, etc. all via unsecured broadband). After I undo the damage (sometimes rebuilding from scratch in serious cases), I leave them with five things: ZoneAlarm, or preferably, a broadband router/firewall; Spybot, set to automatically update and scan nightly; AVG from Grisoft, also set to update and scan nightly; Windows Updates set to do its thing automatically, and Firefox. User is advised to stop using IE. I have yet to have anyone call me with further issues after months. Case closed, as far as I’m concerned.
