There is nothing wrong with taking less than adequate measures to prevent a bigger damage to anything you treasure if you have financial or other constraints, as long as this is done temporarily over a short time. Similar reasoning applies when it comes to computer security threats.
Unfortunately some (if not most) computer users tend to forget this. They search on the internet for free computer security software which they dump into their computers and hope for the best. Most of the free software developers consistently forget to inform the downloaders of the inadequacies of their software – and they are many and significant!
A simple search for free anti-spyware programs on any search engine yields significant results. If we exclude genuine beta-software from these results, almost all of these anti-spyware programs operate on the principle – “Get infected first, then call us”. In other words these programs are reactive. They scan and destroy spyware as it’s found in the user’s computer. The real downside of these programs is that they offer no real-time protection. Are you surprised? Maybe you’ve forgotten that “there’s no such thing a free lunch”!
