This is just a fun thought. Hacking as easy as 1-2-3. Heck, if you managed to get to this article, you have the tech savvy to break virtually any online business. Will you? Probably not. But it’s a great show of why so much time and energy are put into developing and implementing computer security systems. Whether we’re talking about protecting your business or protecting your PC, geniuses have spent thousands of hours working it out so you just have to click and buy.But how much protection does your computer need? Everyone knows they need an antivirus program, because stuff happens. Of course, there’s a few free ones out there, so make sure you shop around. Beyond that, you’re going to want to look into the only-slightly-more-advanced spyware blockers, which do basically the same job but for a slightly different attacker.But as you look up and up and what you might have happen, consider a few key questions:What are you protecting?How likely is an attack against you?How hard is it to replace what you’ve compiled, and what’s the risk if someone else gets it?If you’re in the low-risk category, consider backing up key files, like photos, videos, and important documents, onto an external hard drive and resting easy. In the long run, they’re cheaper than a high-end security system.If you’re in the higher-risk category, you can get all kinds of protection, like security programs specifically for your email, instant messengers, and even video games. Just make sure you shop around, and watch out for introductory offers that fade away to expensive subscriptions. Of course, for all your protection, just remember that something unexpected can always come up.
