Difficulty: Moderately Easy
Eliminate Viruses and Spyware
Step1
Run your antivirus program. There may be something slowing your computer that you can remove. It is a good idea to run your antivirus program every week.
Step2
Remove spyware. Run a good spyware tool at least twice a month.
Step3
Use a pop-up blocker, if you have one. Check your antivirus program.
Dispose of the Extras
Step1
Delete your document files for anything you no longer need. Saved pictures, audio and video files in particular can slow your computer.
Step2
Remove unwanted programs from the Control Panel area. Old toolbars or games the kids downloaded off the Internet are a good place to start. Look for software you no longer use, such as the old printer you threw out last year.
Step3
Clean out your email. Old messages are a constant drain on your computer's resources. Go through every folder, deleting everything you do not need. Leave no mail! Finish by emptying the Deleted Items folder.
Step4
Turn off unnecessary programs. Check your taskbar for icons that show running programs. Disable anything you are not currently using.
Run Maintenance
Step1
Run the Disk Cleanup tool located in your Control Panel. (Windows only. For other operating systems, please check the Resources section below.) This will remove temporary files, cookies and unnecessary components to speed up your computer.
Step2
Defragment your computer. Defragging takes some time, but will speed your computer significantly. You can find the tool in your Control Panel. Run it monthly.
Step3
Check for disk errors. Sometimes corrupted files slow down your computer. To find and fix these files, Go to My Computer and right-click on C drive. Choose Properties, then Tools.
