If you're looking for software to ensure that your computer is in the best running condition possible, then you'll want to check out Advanced SystemCare. This particular program comes in a free and paid version, although I recommend the paid version, which costs around $20 or so per year. You'll get malware protection, virus protection, and optimization software to ensure your computer is running as smoothly as possible. Other add-ons include an automatic driver booster, a file shredding program, and more. It's well-worth the price, and I've been using this software for about three years now.
