Just like investing money, the safest ways pay the least, but you don't get viruses. The videos give 1-5 points each (sometimes more) - and they update and get new ones fairly regularly so just keep tabs on that. I just start up RadioLoyalty first thing in the morning, set it to the 70's station (I'm old) and let it run in the background all day, sometimes turning it up for an old favorite. Every ten minutes or so I do the captcha and there's 5 points. Surveys are hit or miss, but most of the ones I've done have payed, but they're more time consuming. For anything that requires an installation, I have an old crappy laptop at work that I use so that my main computer doesn't get any viruses or spyware or other malware.
