Spyware Protection searches needn't be hard; instead of normal results, check the latest and newest ones. Using an engine with advanced search by date while doing a spyware protection search will get you the freshest results. Some of the best search engines give you in addition a 'pages like this' option to give you yet more pages of all kinds.
In a search engine, when trying to look for spyware protection see more relevant results by using a string which includes the phrase, and also having the phrase within quote marks. Sites in the search engine listings will be better because you have enforced more precision.
You will find occasionally that the spyware protection site you want will not be seen by anyone using a search engine (despite it being still up): probably because there were technical problems at the web site's host or the server needed a reboot when the search engine's spider visited. When this happens you could try to guess the url and start typing it in the address field and your browser may remember the rest.
If you are looking for the most worthwhile spyware protection sites many more listings can be seen in compilations featuring 'best of the web' collections in which quality sites only are included. Long ago when people didn't search these human-selected guides were popular but not any more because of success of the big search engines.
If a spyware protection related listing is offered by a search engine and you can't get to the site: don't worry, this is not uncommon. When it happens, hit the Back button, and use the cache feature to access the page as it looked at the last crawl.
