Updates & Patches
Patches are small applications supplied by the software developers that are intended to fix a bug in their products. Usually patches do fix the problem, but there have been occasions when a patch fixes one problem but causes another.
Vendors typically provide patches at no cost to their customer on their web site or you can be notified of new patches via email if you subscribe to a mailing list. Most software applications automatically check for updates on the internet and then notify you so you can download and install them.
Making sure your software is patched is important because hackers have been known to exploit the vulnerabilities and risks that unpatched applications pose. Please take care when downloading patches to make sure that they are from a legitimate source.
