Install the Personal Software Inspector to keep on top of security flaws with programs on your computer. This application, free for personal use, can analyze your system with a quick scan and see if there are any ‘insecure,’ ‘end of life,’ or ‘patched’ programs. With an easy interface, you can find out which applications on your machine are considered up to date and which are easy targets. For some programs listed as having problems, there are even quick links to download updates or investigate the issue further. All in all, a great tool for the security conscious who would enjoy a little more convenience.
