Summary

I have run the full spectrum of Comodo products on diverse systems. My experience is that it installs, runs, and performs great on all Intel processor based systems, but beware of systems based on AMD processors. This is not to fault AMD, but likely inattention on Comodo's part. I have made them aware of this on two distinct occasions and the response I recieved seemed one of interest initially, then they seemed to want to sweep it under the rug as though the engineer eschelon was already aware of the issue. Hmmm ... In any case no satisfaction was forth coming, and I therefore had to make sure that no AMD systems had Comodo installed. That ended the issues. Hope this helps someone else avoid headaches.

Have this for a long time now 3 years
I find this one of the best i have found on the internet.
Better than avg and many other.
Even better than paid progs like norton or avg.
