As you browse the Internet, your computer collects bits and pieces of information that can eventually build up to the point that they cause performance issues, especially on older and slower machines. The most basic way to do this is by using the tools that come with your Internet browser of choice. Microsoft Internet Explorer users on Windows can clear all temporary data by visiting the Internet Options control panel item and clicking the Delete button on the General tab under the Browsing History subheading.  If you're using IE on a non-Windows computer, simply open the Tools menu, choose Options, and select the data you want to clear.     To erase temporary files, cookies, and cache data from Firefox, open the Firefox menu and open the Options window (this may require selecting Options from the drop down menu and then selecting Options again from the menu that appears). Once there click the tab or button that says Advanced, and then choose the Network tab underneath that. Find the box that has Offline Web Content in its header, and click the Clear button to clear your data.     To clear data from Chrome, simply hold down Control and Shift, and type Delete (as opposed to the Backspace button). A new tab will open up with a simple menu. Select the data you want to erase, set the time frame using the box in the upper right, and click Clear Browsing Data when you're satisfied.     To reach this menu the old-fashioned way, click the button with three horizontal lines on it in the upper right corner of the browser, and choose Settings from the menu that appears. Scroll partway down the screen to find the Privacy heading, then click the “Clear browsing data” button right underneath it.     To clear Safari's browsing cache, go to the Edit menu and select Empty Cache. Confirm your decision when asked.     If you have not sufficient time to perform these tasks you can use some browser cleanup tool. Adware and malware are types of programs that can compromise your computer's performance and create security weaknesses. There are specialized free programs designed to find and erase adware and spyware.  Install and run the program (it's pretty straightforward) to find and delete offending files.  Mac users don't have many comprehensive options. The best-regarded overall is  MacScan, which is powerful but costs money to use for more than 30 days. Fortunately, the cost for a home license is fairly low at just $39.99. Download the free trial first to be sure it'll work for you.     The best way to avoid adware and malware is to never download anything you're not sure of, and never agree to install anything extra that comes packaged with software you choose to install.    The best way to defend your computer against truly malicious threats is with a powerful antivirus program. Both Mac and Windows users have access to good free options that work at least as well as paid brands. Install them and allow them to run in the background at all times. When you first install them, or if you suspect a virus may have been missed, you can run them manually as well. Since new viruses are always being designed and released, it's very important that you allow your antivirus program to update as often as it needs to. Normally, this should take place in the background, without you having to do anything.    Most computers made within the last several years take care of these tasks automatically, but you're always free to take care of them yourself if you want. The key tools are (1) disk defragmentation, which organizes the jumbled bits of data on your drive so that they can be found more quickly, and (2) disk cleanup, which deletes duplicate files and unused temporary ones to free up space.  Since the location of these tools varies from version to version of Windows, it's best to use a Start Menu search to find them quickly. Simply open and run them from the search results to speed up your computer, if the tasks haven't already been scheduled to run automatically.     Mac and Linux users don't typically need to defragment their hard disks, as the process is ongoing and automatic in the background. Mac users can clean up their hard disks with the Disk utility, located in the Utilities folder (normally inside the Applications folder on OS X systems).    If you have extra programs, you remove them easily on Windows by using the Programs and Features (newer) or Add/Remove Programs (older) control panel. Highlight a program to see available options, and click to completely uninstall it. This is preferable to simply deleting the application yourself, as it removes files the program may have installed elsewhere as well. Mac users can generally get away with just dragging unwanted programs into the Trash, but the process to fully remove things like Preference files and other scattered pieces is considerably more complicated – too complicated to cover in this guide.    Once you've cleaned up your computer, it's time to preserve it in time so you can go back to a clean version if anything catastrophic happens in the future. This works quite differently depending on whether you're using a Mac or Windows, but the process is simple in either case.  Windows users should do a Start Menu search for “system restore,” and choose to create a restore point, which the computer can be rolled back to in the event of a disaster.     Mac users should set up Time Machine, a system preservation program, to run in the background. Time Machine allows you to roll back specific recent changes to rectify compatibility and other problems.     In either case, backing up to an external hard drive is recommended. Both methods require a lot of free space, and the external hard drive may be spared if the main hard drive has a mechanical malfunction.
