I had gotten a virus and after using the online scan purchased the panda software because it only installs anti-virus(trend and norton install full protection suites that I don't want).

I have been using Titanium for 6 mos now.. I am IT manager, I say that from a credibility standpoint. The Titanium has performed in a steller manner. In fact I prefer it over the platinum. This is robust AV which uses relativley little resources. The auto update and permanent protection features are invaluable plus they really work. I ran repeated EICAR tests and Panda performed 10 of 10. Great app. Will never go back to that Norton rubbish
