Despite millions of website offering free anti spyware download, the task of finding best free anti spyware is a non-trivial one. It is comparable to finding a needle in a haystack. In other words, it is easier said than done.

The difficulty, of course, lies not in finding a website claiming to offer best free anti spyware – there's an unlimited number of them in all domain zones. The problem is that "best free anti spyware" search query is a misleading term because attempts to find something "best" for free are to fail.

If you never imagined what is hidden behind the simple notion of anti spyware, then think of it for a second. Anti spyware is not a text processor that can be updated once a year – it needs daily updates to provide the users with top-notch protection against new threats. A special security lab monitors the Web to gather the reports, analyzes feedback from customers, and collects the data to identify threats with high potential (that is, those threats that can potentially cause damage to lots of PC's worldwide). Then, the results of analysis and combined recommendations are delivered to highly skilled programmers who code the definitions that reflect the new spyware threats. Later these definitions are uploaded to central servers and delivered to users of desktop anti spyware software, either via automatic updates, or are downloaded manually by users. Note that designers and maintenance team of the manufacturer's website have to keep the pages up-to-date.

This load of work never can be done by enthusiasts of "best free anti spyware", therefore usually the words "free" and "best" should not go together.

Really best anti spyware also features real-time scan of incoming connections, running system processes, open applications, launched programs, etc. Moreover, a special heuristics module powered with intelligent algorithms should be able to predict the impact on the system of any single executed file, therefore it analyzes the chains of bytes in the system memory. This helps to prevent the possible damage from the spyware. Very few software manufacturers can afford to develop and support of this highly sophisticated anti spyware.

Best free anti spyware is incapable of such advanced monitoring because the development of technology enhancements requires dedicated work from a team of software coders.

Usually free anti spyware is offered as a marketing tool to let potential customers use the software for a prolonged period of time. But free anti spyware lacks advanced features as those described above.

Nowadays the gap between "best" and "free anti spyware" is getting wider and wider, because the spyware protection is in high demand both by home users and businesses.
