Rated 1 out of 5 stars
This add on is essentially a come-on. Like those myriad of 'speed up your computer,' and 'remove virus', etc. from your computer' commercials, this 'add-on' tells you (if you have malware,etc), your computer COULD be healthy - if you just PAY for the FULL version.
The simplest way to not have to worry about virus, etc., is to have good protection software ALREADY on your computer (and keeping it current). Another simple thing to do - buy a Mac. 99% of all these computer bugaboos are on PC's.
Last word: This add-on is a waste of time, and might cause you more problems if you use it.
