The first action that spyware software typically makes is to make an outbound request. This is usually the spyware contacting a website. More often than not, inspection firewalls are very effective here as they will warn users when any software makes an outbound request.
This is very effective spyware blocker protection that can save anyone lots of grief. In actual fact spyware blocking software can be extremely effective, although one needs to be very careful not to purchase or download free fake spyware blocker which in many cases will install spyware programs into your computer rather than protect you from it.
I want to recommend genuine and effective spyware blockers that are available for free online. There is the Google one, and also the Windows XP Service Pack 2 that both blocks and destroys spyware from any computer. Both can easily be obtained for free by downloading them. All you need to do is to go to the Google tools menu and simply activate the pop-up blocking feature.
Other effective anti-spyware software includes Mac Scan for mac users and the popular McAfee which is however not free. It can be purchased onlibe for around $ 50 at the most.
So what determines the effectiveness of a spyware blocker? The answer is the database. The more extensive the database the more effective it will tend to be as protection against the many types and strains of spyware.
It is important to be aware of the fact that some spyware blockers do not eliminate spyware and only warn the user about an invasion. Sometimes this warning may come when other files have already been infected. This means that even as the files the software has pointed to are dealt with manually, the spyware will already be embedded in others that the use has not been warned about.
