What many people may not realize is that computer viruses, malware and spyware rely on your computer's operating system, anti-virus software and your installed computer programs being out of date in order to infect your system. If you're not sure how, or don't allow regular automatic updates, your computer and it's software may be out of date. It is important to keep your computer software and operating system updated.
The first thing you can do to keep your operating system and virus software up to date is to pay attention to system notifications. When you see a little pop-up from your system tray asking you if you want to update, make sure you follow through and use Windows Update to update your operating system.
The most important thing you can do is enable windows automatic update which will let your Windows operating system scan, download and automatically install important updates which will help keep your system more secure. In addition, virus definitions are often released daily, and while you may not need to update your anti-virus software daily, enabling automatic updates in your anti-virus software will ensure that the next time you scan for infections will be more effective as your software definitions are updated.
