Cleaning your system's registry, temporary files and hard disks not only makes your computer's performance better, it can increase your system's security. Because home users surf the internet on a daily basis and average more than 15 hours each week online; temporary files from websites are downloaded to their hard drives. Temporary files are downloaded to assist computers when reloading websites. These files are loaded from the hard drive when a website is revisited to assist in speeding up the webpage loading. Often malware and spyware are loaded from malicious websites into these temporary files causing the system to be infected when they are downloaded or when the system comes across these files.
Keeping your system clean is an important fundamental step in protecting your computer. Your privacy on a computer can lead a malicious user to not only where you surf on the internet but to secure sites that may still contain some of your critical information.
