You may have seen our article here listing the Top Five Anti-Spyware programs. However, there is something interesting to mention about SpywareGuard.
SpywareGuard actually hasn't been updated in several years. You may think of this as a bad thing, but it really doesn't make a difference.
See, SpywareGuard does not rely on definition updates like most anti-spyware programs. Instead, SpywareGuard relies on looking for suspicious activity on your computer as signs of a possible spyware infection such as added Browser Objects, Homepage being changed, etc.
Because of this, SpywareGuard is just as effective as it was the day it was released. EasyTechReviews.com definitely recommends it.
