Don't blame whatever OS, sounds a bit like your dads fault to me
Did I mention every other internet-enabled PC in the house was running Linux, and hasn't been hit once? This Windows machine is the only thing with the problem, and it's not like he hasn't looked into it. The trouble is, as good as our firewall is, it ultimately just delays the virus problem.
The system has simply less viruses, because virus programmers
want to target the more popular platforms (Windows),
and there are more Windoes platforms that can spread the viruses.
You have a point here, but that's not really the problem. You see, Linux uses a much different file structure than Windows, such that every file on your PC uses permissions. For example, if a user runs an application, he can only modify a text file if the user owns the the text file as well. Even if a virus landed on your Linux machine, it wouldn't be able to do anything since it doesn't "own" any of your files. The whole kernel would just reject it. Windows doesn't have this; if a virus lands on your machine, it can do anything, anywhere. You're totally defenseless.
