There are generally 3 types of things you should protect your computer from at all times. Those are viruses, spyware and adware. There are various software programs that will help you protect your computer from them, some are free and some you will pay for. Some of them will help you protect against 1 or 2 of them combined, so those are worth looking out for as well. There is also a free spyware blaster program that will protect against spyware from even entering your computer.

By preventing spyware from entering, you are essentially putting up a barrier that they cannot get through. It is always better to prevent than to cure, so the free spyware blaster does a very good job and well worth the time to install it. Once it is installed, you don't need to do anything else. It doesn't take up any resources but will just continue to protect.

It will stop things like Active-X spyware, most types of adware and all other malicious programs from gaining access to your computer. Unlike other programs, you can even set it to prevent tracking cookies from being placed on your machine too.

If you can combine the free spyware blaster with another adware scanning software tool, such as Adaware, then you have a combination that should see you 100% protected against any form of spyware and adware. Both are free to download and use too, so won't cost you a penny.
