There are many reasons why your computer may be running slower than normal. One of the main causes is your systems registry. The registry in your computer is the systems main brain and stores everything you do. So, every action you take on your computer from turning up the volume to downloading a program makes an entry in the registry.
Over time your registry becomes bloated or even corrupt. If you uninstall programs without using the uninstall feature you will end up with left over fragments of the program in your registry and this can create a problem with speed as well as how your system functions. Malicious software is another cause of a corrupt registry. If you surf the internet chances are you have been infected with some sort of malicious software. Adware and spyware are very common and sometimes missed by your antivirus software, but viruses and Trojans are fairly common as well for those who download files from the internet. You can run your antivirus software to try to remove the malware from your system but in many cases it will still have fragments left behind in the registry.
The best way to deal with your registry problems is to download a registry cleaner. Trying to mess with your systems registry on your own can be not only tedious, but risky as well. You do not want to chance making a mistake that will alter how your system works, so let the program do it for you. Always be sure that you use the backup option in the program before you make any changes to your registry, just in case the program removes something you might have needed. If after cleaning the registry of all errors you still notice your system being slow, you might want to consider storage space, memory issues or even malfunctioning hardware as the cause.
