Trend Micro Titanium security system is so smooth you hardly know its working until if finds something that could damage your PC. I had a different security software on my PC and though it was a really popular brand it was using way to much RAM and way to much virtual memory , my computer was slow and responded sluggishly. This was a problem because I have to move quickly through my computer work often having up many tabs and running programs. It was frustrating to be held hostage by my security often making me miss out on something good while it slowly performed the necessary tasks . NOT so with Trend Micro Titanium security system. This is an awesome system, fast yet secure, complete yet not invasive. It provides you with the very best in security yet allowing you to do what you have to do online without slowing things down. I will be using the security system from now on and of the many I have tried this is by far the greatest value . I was given a free download of this product through bzzagent as I am a bzzagent and get to try wonderful products like this . thanks for looking at my review.
