content: I'm using Panda Free on a few laptops and have no problems. It has removed a few infections from one system with ease and the scans work like a dream (there is options for what type of scan you wish to do, like optimised, single/multiple drives or a full system scan). You can order Panda to scan individual files, e.g. if you download a .zip from somewhere and it looks a little risky, simply tell Panda to scan it and it'll deem the contents safe or unsafe before you open it, this has saved my ass a few times! The free version will occasionally throw a pop-up PandaPro advert in the corner, once you click (x) it won't appear in the session again.
