Who doesn’t like free stuff? While there’s no shortage or free software available there’s plenty to be wary of. If it’s from a major software company then it’s probably trustworthy. And when in doubt, there’s always Google. Do a search and see what people say. Undoubtedly there will be crapware that comes along with “free” software, but that’s just the price you pay for “free” software. Be prepared to spammed on a regular basis about the benefits of upgrading to the paid version.
By all accounts DO NOT click on those popup ads which claim to have detected a virus on your computer. Those type of tactics will most certainly install some sort of malicious program on to your computer. *tsk *tsk those pesky cyber criminals just keep getting more clever every day.
It you do have to test out some questionable software, don’t install it on your main computer. Set up a stand alone box, disconnected from the network and Internet and go nuts. Don’t forget to scan easy install file before running it. When you’re done with it, uninstall it. It may not be malicious now, but there’s no telling what it will do next week.
