Smartphones and tablets have heralded the touch revolution. Computer mice and on-screen cursors are starting to feel antiquated. And yet there is a problem.

For all its expediency and efficiency, touch still runs mostly like a mouse cursor. So we added more contact-points: enter multi-touch. But now there's another problem, how do we plan out a schema that properly uses multiple touch points?

Well, there are different proposals for that. But perhaps the best answer is something completely different.

We use our cars every day, and we use them hard. Stop-and-go traffic, accelerating and then hitting the brakes. Weighing the vehicle down with passengers and cargo. It's a lot of wear and tear.

But even if we treated our automobiles with tender, loving care; just over time they fall into gradual disrepair. The very act of driving wears down gears and belts, uses up fluids, and generates gunk and rust. It just comes with use.

If we don't bring our cars into the mechanic every so often they're bound to fail on us. Eventually all those "minor issues" just accumulate and eventually can bring the entire vehicle to its knees (or hub caps). Regular maintenance is just a necessity when you want a fully functional, everyday machine.

So why wouldn't you do the same for your computer?

So that DNS Changer "doomsday" finally hit. The FBI took down the malicious redirect servers and as a consequence any machines still "infected and tied" to those servers would have found their Internet connections disabled.

So let's take stock of what happened on this doomsday.

Last time I spoke about how the Webocalypse is not nigh, and that most tech scares are media fluff. That's not to say that there aren't dangers on the Web, and usually it is precisely because most threats are "small" that they are able to infect many systems.

"Anti" programs are all but mandatory nowadays. Antivirus, anti-malware, anti-spam, etc. It can be somewhat confusing for the less tech savvy.

So let's break things down, and best of all, look at the free options available.
