The following are Plugins that are needed for your PC to watch videos online and are highly trusted ,but you should always install programs using the custom option as opposed to the easy instal otherwise you might install additional software you do not require or change your usual search engine or home page in addition I would like to recommend that you use a site adviser when selecting a site to download a particular piece of software although I have taken the time to make sure these are safe downloads I can't guarantee that the software wasn't updated at some later point with malicious features however unlikely that may be .
