A Clean Computer

A clean computer is vital, and is even worth spending a bit of money in-order for you not to spend a lot of money when something goes wrong.
(please be advised that although these programs help, they do not insure that nothing will go wrong with your machine)

1. First on the list is an antivirus anti-spam / phishing, firewall, real-time system protection, anti-theft and parental control, (and more) all in one.  This software is required as a backbone for a healthy PC/Laptop. There are many similar software/companies but this one stands well above the other competitions....

2. This software basically fine tunes your computer into a smooth operating machine. It optimizes your system by disabling software (permanently, or when not in use), disables start-up programs which can slow your start time, and general smoothness of your computer. Cleans registry, fragments registry, removes broken shortcuts, and de-fragments hard drive, and plenty more. It cleans disk space - freeing up space and making the computer more responsive.  Then as a really nice bonus it also has a section that solves common problems, such as icons not showing properly or icons disappearing. And can check your drive for errors, and restore deleted files.

3. One of the worst things about browsing on the internet is the pop ups, whether you just want to see what you clicked, without 100 different windows opens up containing Russian brides just for you, or you don't want you or any family member seeing some of the rubbish that is peddled on the internet. However alot of these pop up blockers, block things that you actually want to pop up. For that reason you want a reliable software that blocks what its meant to, and leaves what it should, and in a situation that it doesnt do that is easy to change and fix.

4. Sometimes you actually don't have anything wrong with your computer but things a crashing or stopping - normally after updating drivers on your computer. For that reason you need a driver updater.
