It’s hard to maintain a secure, virus-free Windows set-up. The Internet is like a minefield, where a poorly protected computer can become infected by all sorts of virii or allow malicious individuals to tinker with your hard drive’s contents, or worse, your operating system itself.
Don’t waste any time getting your Windows computer secured. You don’t need to shell out hundreds of dollars to do this — and if you have a computer that’s not secured already, you may be unaware that not all free software is malicious. In fact, free, open source software makes up a huge chunk of the software ecosystem today, Firefox being one prevalent example.
Which reminds me—if you’re using Internet Explorer, the first step is to grab Firefox, get rid of IE, and come back to this page in your new browser.
Security isn’t about blocking malicious actions, it’s about keeping your data safe. While much of that is about keeping virii or hackers out, it’s also about keeping backups so hardware failure, natural disasters or malicious attacks don’t destroy your primary copy for good.
