Allowing Spyware is telling anyone that wants to know, what you are doing. 

Spyware and other malicious software report your personal information and online activity to hackers, web sites, advertisers and other predators leading to identity theft. Anti-virus software and firewalls don't guard against them. Once a hacker has the information you gave them through the Malware (spyware) - you have given them your computer and your Internet passwords. Your online exchange of information over a secure network may be safe, but if a hacker has access to your computer, your key presses are his - that is, what you type is recorded and transmitted to the hacker - they become you.

SpyCatcher's comprehensive database detects tens of thousands of these threats, from the most common to the most obscure, and SpyCatcher updates itself automatically to provide immediate protection from the latest danger. SpyCatcher is the only anti-spyware title with a Reinstall Shield that defends against advanced, aggressive spyware programs which silently reinstall after deletion.

SpyCatcher even disguises disabled adware as "active" to trick some ad-dependent software into running though its threat has been eliminated. SpyCatcher is the most easy and powerful way to protect yourself from the many malicious programs that bypass anti-virus software and firewalls——don't go online without it!
