It's not going to outpace the paid anti-malware tools for effectiveness, but the easy-to-use Panda is more than capable of keeping up with the freebies. It will even automatically check USB drives you insert and launch a "vaccination" against launched processes on the USB drive. Just watch out during Panda installation as it tries to reset some of your defaults—the price you pay for "free."
If you try to do the work on your own, or simply use the lead management system you have to generate new leads, you will save yourself from potential wasting money buying leads. Especially if you can find success on your own converting leads, there is really no need for you to spend money by purchasing leads that might not be guaranteed to make a sale. If you can do it alone, you might as well put in the extra effort and use your resources to go it your own way.
Freeflys: Another strong contender in the freebies space, Freeflys has appeared on NBC’s Today Show, The Doctors, Fox News and a handful of other media outlets. Similar to most of these sites, Freeflys utilizes email alerts to tell users about free-sample offers as they happen. The site also allows you to search for a specific product with the handy search bar.
