Your web browser is your gateway to the internet and is often times the entry point for computer viruses. It is therefore important that you frequently check for updates to your browser.
Internet Explorer - Updates are includes as part of your Windows updates

Safari - Safari updates are included with Mac OS X updates. To update you Mac, go here.
Apple periodically releases updates and patches that will protect Mac OS X from being attacked by viruses and other malicious programs. Configuring OS X to automatically install these patches will ensure your computer is always protected.
1. Click on the Apple menu, and choose System Preferences.
2. In the window that appears, select Software Updates from the System section.
3. Check the box by Check for Updates and select Weekly from the pull–down menu.
4. Check the box by Download important updates in the background.
Microsoft periodically releases security patches for Windows operating systems. Downloading and installing these updates will help protect your computer from viruses and threats. All you need to install updates on your computer is an active internet connection, and the instructions below:
Click the Start circle at the bottom left of your desktop.
Click the All Programs option at the bottom of the menu.
Click the Windows Update option in this list.
Note: If a link for Windows Updates does not appear in this list, you can always access it by opening up the Control Panel.
A separate window should open. When it does, select the Check for Updates option on the left-hand menu. Windows will then go online and check for available updates.
When the check for updates is finished, Windows will display a screen similar to this one, letting you know how many updates were found.
Note: if no updates are found at this point, you already have all the latest updates installed.
If you notice that the number of updates available and the number of updates selected is different (as it is on the screenshot to the right), or there are optional updates available, you should click on the link to view the list of updates and select any that are missing.
Note: Sometimes Windows will leave certain updates un-selected if they are large and will take longer to install. These are still important updates, and should be installed if you have the time to let your computer sit and install them.
If it already says you have all the updates selected, you can skip to step 6.
This screen should display a list of available updates. Check the box at the very top (the one above the list). This will select all the updates in the list for installation.
If you have optional updates available, you can click the Optional tab on the left to view them. If you see things like language packs or toolbars (like the Bing desktop toolbar), you can leave them un-checked because they are optional software. If you see any general updates in this list, it is a good idea to check the box next to them for installation.
Click the OK button when you are finished selecting updates
You should now be looking at the same screen as Step 4. Click the Install Updates button, and Windows will begin downloading and installing your updates.
You will see a progress bar similar to the one on the screenshot to the right. This will show you the current progress. Once the progress bar is full, Windows will be finished installing your updates!
Note: Windows may ask you to restart your computer when updates are done. If it does, it is a good itea to restart right away. Also, if you had a lot of updates to install, you should run through the steps on this page again after your computer restarts, as additinal updates may become available after installation.
